"The conventional wisdom about Ukraine's nuclear weapons is wrong. In fact, as soon as it declared independence, Ukraine should have been quietly encouraged to fashion its own nuclear deterrent. Even now, pressing Ukraine to become a nonnuclear state is a mistake. A nuclear Ukraine makes sense for two reasons. First, it is imperative to maintain peace between Russia and Ukraine. That means ensuring that the Russians, who have a history of bad relations with Ukraine, do not move to reconquer it. ... Ukrainian nuclear weapons are the only reliable deterrent to Russian aggression. ... A conventional war between Russia and Ukraine would entail vast military casualties and the possible murder of many thousands of civilians. Russians and Ukrainians have a history of mutual enmity; this hostility, combined with the intermixing of their populations, raises the possibility that war between them could entail Bosnian style ethnic cleansing and mass murder. This war could produce millions of refugees clamoring at the borders of Western Europe. ... There is also the threat of escalation beyond the borders of Russia and Ukraine. For example, the Russians might decide to reconquer other parts of the former Soviet Union in the midst of a war, or might try to take back some of Eastern Europe. Poland and Belarus might join forces with Russia against Ukraine or gang up with Ukraine to prevent a Russian resurgence. The Germans, Americans or Chinese could get pulled in by their fear of a Russian victory. (Doubters should remember that the United States had no intention of fighting in Europe when war broke out in 1914 and again in 1939.) ...
"Russia has dominated an unwilling and angry Ukraine for more than two centuries, and has attempted to crush Ukraine's sense of self-identity. Recent history witnessed the greatest horrors in this relationship: Stalins government murdered an astounding 12 million Ukrainians during the 1930s. ... A Ukrainian conventional deterrent is not a viable option because Ukraine cannot build an army powerful enough to stop a Russian attack. Ukraine's army might put up dogged resistance, but it would eventually be defeated. Russia is simply too powerful. ... Conventional military power is significantly more expensive than nuclear military power and requires a larger military; hence it requires far more popular mobilization. ... A security guarantee from the West is theoretically possible but not a practical strategy for maintaining Ukrainian sovereignty. Extending deterrence to Germany during the Cold War was a demanding and expensive job; extending deterrence further east to Ukraine would be even more difficult. ... Vilifying nuclear weapons is a fashionable sport in the West. ... This view of nuclear weapons is simplistic and flies in the face of the inherent logic of nuclear deterrence, as well as the history of the Cold War. In fact, nuclear weapons often diminish international violence, and Ukrainian nuclear weapons would be an effective deterrent against a Russian conventional attack or nuclear blackmail. In the pre-nuclear world of industrialized great powers, there were two world wars between 1900 and 1945 in which some 50 million Europeans died. In the nuclear age, the story is very different. Only some 15,000 Europeans were killed in minor wars between 1945 and 1990, and there was a stable peace between the superpowers that became increasingly robust over time. ... Moreover, there is always the possibility that nuclear weapons might be used inadvertently or accidentally in the course of a conventional war, which provides further incentives for caution."
Below: 13 July 2024 Russian State TV Channel 1 (Putin's Kremlin controlled Russian language propaganda channel for the Russian people): "Any confrontation with the NATO bloc is possible only with the use of nuclear weapons. There is simply no other option. If NATO's military organization surpasses us, it is absolutely futile for us to enter into such an armed confrontation with conventional means of destruction only."
NO: this is not "just a bluff". Putin has over 2000 tactical neutron bombs; we have damn all now. OK? We DID have dedicated tactical nuclear weapons until 1992, and they deterred Russian invasions, but since then we have cut back our deterrence to a bare minimum which excludes the deterrence of conventional wars which risk escalating (like the invasions of Belgium in 1914 and Poland in 1939) into a World War, despite Herman Kahn's warnings of the dangers from minimum deterrence in his 1960 book On Thermonuclear War.

"If we are able to use these weapons, and the enemy does not have them, their military effect can only be matched by his use of larger-yield dirty weapons - with the political and propaganda penalties their use implies. Of course the converse will also be true." - Samuel T. Cohen, Low-yield fusion weapons for limited wars, RAND report R-347, 1 June 1959, Secret - Restricted Data classified, p.2 (note this report is based on Livermore laboratory's very clean low yield Dove and Starling devices, developed after the successful testing of 95% clean 4.5 megaton Navajo and 85% clean 3.53 megaton Zuni at Bikini Atoll in 1956 which had lead pushers; Cohen's declassified paper is now in Eisenhower's Presidential Library with annotation on the front cover proving President Eisenhower was briefed on it in 1959!).
"There is another way in which we can have too narrow a focus. We can refuse to entertain or consider seriously ideas which seem to be 'crackpot' or unrealistic, but which are really just unfamiliar. In more casual days one could dismiss a bizarre-sounding notion with a snort or comment about it being impractical or implausible. Things moved slowly, and no real harm was done if a new idea took several years to prove itself. Indeed, allowing a notion to stay around for several years before giving it serious intellectual attention meant that most of the 'half-baked' ones got scuttled and never had to be considered seriously at all." - H. Kahn, On Thermonuclear War, p125.
ABOVE: Secret "For Official Use" and individually numbered Russian nuclear defense manual (169 pages long) entitled "КРАТКИЙ СПРАВОЧНИК ПО БОЕВЫМ СВОЙСТВАН ЯДЕРНОГО ОРУЖИЯ" [= "A Brief Guide to the Combat Properties of Nuclear Weapons"] states: "Ядерное оружие обладает значительно большей разрушительной силой по сравнению с обычными видами оружия, но существуют простые и надежные методы защиты от него." [= Nuclear weapons have significantly greater destructive power than conventional weapons, but there are simple and reliable methods of protecting against them.] It adds: "В этом руководстве представлен краткий обзор ядерного оружия, средств и методов защиты от ядерной угрозы, а также инструкции о том, как действовать в случае применения ядерного оружия." [= "This guide provides a brief overview of nuclear weapons, the means and methods of defending against a nuclear threat, and instructions on what to do in the event of a nuclear weapon being used."] The manual contains data tables on damage to Russian military equipment based on Russian nuclear weapons tests, as shown above (this manual is the 2nd edition, dated 1969, but since Russian atmospheric nuclear tests ended in 1962, the data is still valid today). This proves Russian preparation for tactical nuclear war is true. Note particularly Table 41 at pages 92-93, where severe damage (destruction) radii are given for Russian tactical nuclear missiles, cruise missiles, jet fighters, jet bombers, nuclear artillery guns, anti-aircraft guns, mortars, light and heavy machine guns, light and heavy grenade launchers, for air and surface bursts and for 13 yield classes from 1 kiloton to 1 megaton (including the calculated damage pressures in kg/cm^2, separately shown for surface and air bursts). Also, note that it compiles Russian data on measured EMP from nuclear tests in Tables 23 and 24 on page 71 in Chapter 5, "Electromagnetic Pulse", showing the induced voltages as a function of weapon yield, type of conductor (aerial or underground buried power cable), and distance from ground zero. This proves Russian capabilities to use EMP effects from nuclear weapons. For example, Table 23 shows that 10 kV was induced in a 10m aerial at 3.3 km from a 1 megaton low altitude detonation. Note also that Russia found (Table 38) that forest area fires (not isolated fires) cannot occur after surface bursts in coniferous forests even at megaton yields, because of the low angle of elevation of the fireball and because the blast wave following the heat flash blows out most fires, although fire can occur in deciduous and mixed forests.
"The exercises offer a rare insight into how Russia views its nuclear arsenal as a cornerstone of its defence policy — and how it trains forces to be able to carry out a nuclear first strike in some battlefield conditions. ... The slides summarise the threshold as a combination of factors where losses suffered by Russian forces “would irrevocably lead to their failure to stop major enemy aggression”, a “critical situation for the state security of Russia”. ... Russia’s military is also expected to be able to use tactical nuclear weapons for a broad array of goals, including “containing states from using aggression ... or escalating military conflicts”, “stopping aggression”, preventing Russian forces from losing battles or territory, and making Russia’s navy “more effective”. Putin said last June that he felt “negatively” about using tactical nuclear strikes, but then boasted that Russia had a larger non-strategic arsenal than NATO countries. “Screw them, you know, as people say,” Putin said. ... The documents reflect patterns seen in exercises the Russian military held regularly before and since Putin’s full-scale invasion of Ukraine in 2022. ... While Russia’s president has the sole authority to launch a first nuclear strike, the low threshold for tactical nuclear use set out in the documents conforms with a doctrine some western observers refer to as “escalating to de-escalate”. Under this strategy a tactical weapon could be used to try to prevent Russia from becoming embroiled in a sprawling war, particularly one in which the US might intervene. Using what it calls “fear inducement”, Moscow would seek to end the conflict on its own terms by shocking the country’s adversary with the early use of a small nuclear weapon — or securing a settlement through the threat to do so." - Max Seddon and Chris Cook, "Leaked Russian military files reveal criteria for nuclear strike", Financial Times newspaper (UK), 28 Feb 2024.
ABOVE: the 11 October 1952 cover of Picture Post showed clearly the "separation of effects" in an air burst (31 kiloton air burst at 3,440 ft, the Charlie shot of 22 April 1952, Nevada test site), where the fireball cools and forms into toroidal shape (with the radioactivity in the ring) before the "stem" of popcorned dust from the desert is sucked through the middle, before cascading harmlessly around the periphery without mixing with the fission products in the toroidal ring. Despite the visual proof that intense radioactive fallout can be avoided by air bursts, anti-nuclear propaganda helped by Russian fronts continued to raise fallout fears to promote Western arms control and disarmament, leaving the field clear for undeterred Russian conventional invasions and wars.
ABOVE: as Herman Kahn predicted in his 1960 On Thermonuclear War, the paranoid anti-arms race groupthink mob insanity of "disarmament and arms control" public coercion after the first World War was not a fluke, but instead was a standard human reaction to the end of a war. It sowed the seeds of another war! Similarly, after Cold War 1.0 ended in 1991, opposition to disarmament and arms control virtually disappeared, so enhanced neutron tactical nuclear weapons (which deterred the kind of invasions and conventional warfare that led to both World Wars, including nuclear weapons use twice in the second one), were removed unilaterally by the West, allowing Russian aggression to trigger Cold War 2.0. This is basically a repetition of the way fake "pacifist" disarmament propaganda lying by Lord Noel-Baker (who in a BBC radio broadcast in February 1927 first claimed that there was no defense against gas WMD except disarmament) and Sir Norman Angell (who had been at it since 1908 with his "Great Illusion" anti-deterrence book, see his pre-WWI argument with Churchill reported by Professor Cyril Joad in the latter's 1939 book "Why War?"), engineered disaster via populist weapons effects lying, "knockout blow" deceptions, and lying denials of civil defense effectiveness to negate threats (all the lessons of these lies have NOT been learned, and people like Lord Noel-Baker, who lied about gas knockout blows on BBC radio in February 1927, were still doing exactly the same thing with nuclear weapons fallout lies in 1980 in response to "Protect and Survive"!).
You won't find any objective analysis of this in any "history book", all of which follow left wing Marxism propaganda or the anti-nuclear biased CND bigot AJP Taylor, in denying the facts using a data-dump of horseshit propaganda to bury the truth. In reality, as the cartoon published in the 17 May 1919 Daily Herald by Will Dyson shows, people did predict another war by 1940 as a result of the 1919 "peace deal" by Clemenceau, Lloyd George, Woodrow Wilson and Baron Sonnino. But most people prefer to believe lies, a fact shown clearly by an unbiased view of history, or even by an unbiased view of "superstring theory" in physics. But don't dare to stand up for truth, because you'll be subject to lying ad hominem attacks and denied a right to reply and debunk the liars. Power corrupts absolutely because the cowardly crowd backs "fashion", not fact.
This was explained back in 1532 by Machiavelli in The Prince: “It ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things. Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them.”
It was also later explained by John Stuart Mill, On Liberty, 1859: “A general State education is a mere contrivance for moulding people to be exactly like one another: and the mould in which it casts them is that which pleases the predominant power in the government, whether this be a monarch, a priesthood, an aristocracy, or the majority of the existing generation; in proportion as it is efficient and successful, it establishes a despotism over the mind ...”
And don't forget Professor F. A. Hayek, The Constitution of Liberty, Routledge and Kegan Paul, London, 1960, p. 379: “The very magnitude of the power over men’s minds that a highly centralised and government-dominated system of education places in the hands of the authorities ought to make one hesitant before accepting it too readily.”
This attitude encourages the mainstream media or "liberals" to censor anything that debunks their agenda. To recap, anti-deterrence propaganda from bigoted liars is the orthodoxy, and infects nuclear weapons discussions, deterrence discussions, and the entire "arms control and disarmament" movement with crap. Mainstream media would shut down the internet to "protect" people from potential "error". It's all Stalinist censorship, made plain by Orwell's book 1984, but ignored as "taboo" by thug censors masquerading as "liberals".
Kahn made the following point about disarmament and arms control: reducing nuclear stockpiles and unilaterally eliminating Type II Deterrence (i.e. deterrence of the provocations that cause war, e.g., disarming in 1992 the West's W79 neutron bombs to deter the invasions that set off both World Wars) doesn't make you safer, because it increases the risk of war as proved by history. Reducing the risk of an "accidental" nuclear war is best done using ABM, civil defense, plus safeguards inside nuclear weapons, than by disarmanent which increases the risk of war by reducing credible deterrence of war. The idea that unilateral disarmament protects you is like saying that nuclear-unarmed Hiroshima and Nagasaki were safe from nuclear attack in August 1945 because they were so-called "Nuclear Free Zones"! Similarly, the fact the world was non-nuclear in 1939 didn't stop nuclear weapons being manufactured and used to end that war! All of the CND arguments are fake news, just as all the arguments by Angell in 1908 against deterrence were fake news. Fakes news sells - as proved by the sale of fairy tales and "fiction". Even if you don't like particular uses or yields of nuclear weapons, there is a choice of tailored nuclear warhead yields and designs, and types of employment to produce different effects, with widely variable cleanliness, neutron output, EMP output, and the separation of heat, blast and fallout effects in air and subsurface bursts, to deter invasions without the collateral damage that accompanies conventional warfare.
ABOVE: the Russians have recently released a PDF of their detailed technical nuclear effects analysis of the survival of their cheap civil defense dual-use style (basement car park etc in peacetime) nuclear war shelters: "Civil defense shelters. Designs and calculations" by VA Kotlyarevsky, VI Ganushkin, AA Kostin, et al.; edited by VA Kotlyarevsky. - M.: Stroyizdat, 1989 (607 pages long, 144 references, full of equations and graphs). (Russian: "Убежища гражданской обороны. Проекты и расчеты" / В.А. Котляревский, В.И. Ганушкин, А.А. Костин и др.; под редакцией В. А. Котляревского. - М.: Стройиздат, 1989. https://tehne.com/library/ubezhishcha-grazhdanskoy-oborony-konstrukcii-i-raschet-moskva-1989 ) This tells you that these are not "just for show", but are blast and radiation hardened double-blast door, very high overpressure surviving, very intense fallout surviving protection that fundamentally alters the strategic balance and undermines our nuclear deterrent. This should nukegate the "Scientific American" and other pro-Russian, Western deterrent undermining thugs.
ABOVE: Kahn pointed out in On Thermonuclear War 1960 that the way to prevent invasions and wars in the Middle East is nuclear proliferation of CREDIBLE deterrents (not just nuclear weapons, but also ABM and civil defense shelters to mitigate the civilian collateral damage) that really DETER/HALT INVASIONS (the key is to focus on the 1914 invasion of Belgium by mobilization and concentrated force, triggering WWI and the same for Poland in 1939, triggering WWII): if both sides have a credible, stable nuclear deterrent against INVASIONS (i.e., stable = safe from destruction in an enemy 1st strike, so that nuclear retaliation is guaranteed), you get mutual deterrence and thus peace, not war. And even if one side DOES try an attack, a neutron bomb air burst can discriminately halt the aggression, without any collateral damage (of the sort caused by conventional warfare such as the invasions by the Russians in Ukraine and by Hamas in Israel). Conventional weapons are not a substitute because their mobilization along frontiers causes "crisis instability" as occurred in 1914, leading to war. This is why compact, long-range nuclear weapons to prevent this kind of 1914 mobilization "crisis instability" trigger problem, are required. Nuclear escalation can be deterred, just as gas war escalation was deterred against terrorist states successfully in WWII, by a combination of credible civil defense plus retaliation threats capability. The "all out" use of nuclear weapons is simply a form of nuclear disarmament, that leaves the aggressor open to retaliation by the other side's protected 2nd strike (retaliation) force. We have to get this message out past the fake news and "taboo" superstitions of anti-deterrent warmongering paranoid disarmament quacks and charlatans masquerading as "peace advocates". If you want a "two-state solution" and one of those two states is intent on the racist extermination of the other, it shouldn't require Einstein to declare that pressurised "peace talks" are going to be "double-talk"; the slavery issue of 1861 in America wasn't resolved by a "two-state solution" with the southern Confederacy one state and the northern Union the other, nor was the protestant-catholic conflict in Northern Ireland resolved by a "two-state solution", but by a single-state solution with power sharing. You don't resolve a conflict by pressurised "peace talks" or "declarations" between leading opponents in bad faith, but only by genuine accommodation of differences at grass roots or street level. This is why conflicts and wars come before peace settlements. If you really want a "two-state solution" between bitter rivals, you need a credible deterrent to keep the peace. Machiavelli or Marx? Truth or lying? That's the choice.
Glasstone and Dolan stated in The Effects of Nuclear Weapons (1977), Table 12.17 on page 546, that the median distance in Hiroshima for survival after 20 days was 0.12 miles for people in concrete buildings and 1.3 miles for people standing outdoors. Therefore the median distances for survival in modern city buildings and in the open differed by a factor of 11 for Hiroshima; the difference in areas was thus a factor of 112 or about 120. Hence, taking cover in modern city buildings reduces the casualty rates and the risks of being killed by a factor of 120 for Hiroshima conditions, contrary to popular media presented political propaganda that civil defence is hopeless. This would reduce 500,000 casualties for people unprotected in the open (assumed generally throughout Glasstone's book and about 100% of anti-nuclear propaganda) to 4,000 casualties, if people are on the lower floors of concrete buildings.
(NOTE: back in 1990, I completed the unpublished book Nuclear Weapons Effects Theory, debunking Glasstone's "free fields" blast and radiation calculations for modern cities. Basically, the oscillation of, and at higher pressures the plastic zone damage of, modern reinforced concrete city buildings by blast waves is easy to calculate, and irreversibly absorbs free-field blast energy, quickly lowering the overpressure and dynamic pressure to values way lower than measured over unobstructed desert and ocean at nuclear weapons tests and reported by Glasstone. Penney measured this blast energy absorption effect at both Hiroshima and Nagasaki, where the majority of buildings were single storey wood-frame, not concrete. Dr John von Neuman predicted this blast energy attenuation by causing destruction in Los Alamos blast wave secret reports LA-1020/LA-1021, from which it entered Glasstone's 1950 Effects of Atomic Weapons, but Dr Bethe deleted this information from the unclassified summary version, LA-2000, and it was deleted from the later Glasstone Effects of Nuclear Weapons 1957-77, and replaced with a denial of this fact, despite the fact it is a consequence from the principle of conservation of energy, and the exclusion of the effect makes the blast treatment wrong. Similarly, throughout the 1950s the UK Home Office Scientific Advisory Branch calculated thermal effects allowing for skyline shadowing, disproving firestorms and related nuclear winter using this mechanism, but secrecy was used to prevent the information getting wide coverage. Glasstone also mis-calculates all other nuclear effects, for example fallout and cratering are both based on debunked simplifications, exaggerating the effects by large factors. Glasstone entirely ignores all political and military effects of nuclear weapons, as well as the influence of clean secondary stages on the effects of nuclear weapons, e.g. the separation of effects for the air burst neutron bomb. Glasstone's book is really: "The fake effects of nuclear weapons on civilian targets, ignoring the blast and radiation skyline shielding"! Some declassified exaggerations in nuclear threats from Russian tactical nuclear weapons, debunking populist CND/Nukemap nuclear weapons effects propaganda, are presented in NUCLEAR WEAPONS COLLATERAL DAMAGE EXAGGERATIONS: IMPLICATIONS FOR CIVIL DEFENSE. This is treated as "heresy" by the deluded quacks and charlatans of war-making "disarmament" taboos.).
"The critical point is whether the Soviets and the Europeans believe that we can keep our casualties to a level we would find acceptable ... In such an eventuality, the Soviets would be deterred from such provocative acts as a ground attack on Europe ... But if they do not believe that we can keep casualties to a level we would find acceptable, the Soviets may feel safe in undertakng these extremely provocative adventures ... this in itself creates an extremely dangerous negotiating situation - one in which the possibility of extreme pressure and blackmail will always be in the background, if not the foreground. ... 'Will the survivors envy the dead?' Unless the President believes that the postwar world will be worth living in, he will in all likelihood be deterred from living up to our alliance obligations." - Herman Kahn, On Thermonuclear War, Princeton Uni. Press, 1960, page 35. This is Kahn's key argument, explaining the Ukraine war today; a fact always ignored by 100% of "nuclear critics". On page 34, Kahn gives a "notorious" table relating casualties to calculated recovery times for GDP; the GDP recovers in one year if 1% are killed, 100 years if 90% are killed. This difference is similar to the observed 120-fold difference in risk of being killed in Hiroshima if people are outdoors and totally unshielded, to the risk when shielded by the lower floors of modern city concrete buildings. So efficient civil defense warnings make nuclear deterrence over 100 times more credible, reducing casualties and the time taken for economic recovery from 100 years to under 1 year!
Kahn on page 48 of On Thermonuclear War easily debunks J. B. S. Haldane's genetic defects naive propaganda lie for nuclear war, because spreading out damage in time allows survival, whereas having all the damage kill 100% immediately doesn't permit survival. Kahn considers two nuclear attacks (Table 8): an initial 1,500 megatons on 150 targets, and a later wargasm of 20,000 megatons on 400 targets. He then goes into radiation effects lying propaganda by left-wing anti-nuclear disarmament fanatics, before giving the fallout gamma radiation effects much later on, in Tables 23 and 24. For the 1,500 megaton attack, only 1% of the area of the USA gets 6000-10,000R in the first 48 hours outdoors, requiring shelter protection factors of 40-65; for the 20,000 megaton attack, 50% of the area gets this radiation so you need 50 times more good shelter. As a result of these calculations, Kahn argues on p111: "we recommend that about $150 million be spent on identifying, counting, labelling and improving the best radiation protection in every neighbourhood so that people will know where to go...", adding that radiation meters are needed to enable people to go outdoors after 48 hours briefly to decontaminate or evacuate heavy fallout areas before getting a lethal radiation dose in structures offering poor protection. All this was, Kahn points out, published in a 1958 RAND Corp report ignored by President Eisenhower to save a few bucks (it was mostly implemented by Kennedy in 1961). In Tables 12, 13 and 14 Kahn shows how to deal with strontium-90 fallout contaminated food: on page 65 he points out that the linear no-threshold radiation effects theory is fake news for civil defense since the radium dial painters required 20,000 - 30,000 strontium units equivalent to get bone cancer, whereas the official safety limit is just 67 units! So simply by kicking out bad "science" (political "theory" standards) and keeping to actual radiation effects data, you resolve a problem by feeding food with over 25,000 strontium units to animals, and reserving less contaminated food for human consumption. Commenting generally on this kind of fashionable nuclear exaggeration mentality, Kahn explains on p160:
"... we are likely to suffer from the same movement towards 'responsible' budgets, pacifism, and unilateral and universal disarmament that swept through England in the 1920s and 1930s. The effect then was that England prematurely disarmed herself to such an extent that she first lost her voice in world affairs, and later her independence in a war that was caused as much by English weakness as by anything else."
Kahn adds to this on page 568:
"It is difficult and even impossible for most Americans to believe that they have an enemy. This is particularly true of intellectuals and 'men of good will'. ... that all sane men are reasonable and it ought to be easy to clear up misunderstandings by a few meetings and agreements (that is, they believe in what the psychiatrist calls a 'self-fulfilling prophecy' in the sense that 'good will generates good will' ..." Kahn testified to congress that Newman hadn't read his book!

Senator John F. Kennedy forecast in a speech to the Senate on 14 August 1958: "... the deterrent ratio might well shift to the Soviets so heavily, during the years of the gap, as to open to them a shortcut to world domination ... Their missile power will be the shield from behind which they will slowly, but surely, advance - through Sputnik diplomacy, limited 'brush fire' wars, indirect non-overt aggression, intimidation and subversion, increased prestige or influence, and the vicious blackmail of our allies. The periphery of the free world will shift against us." (If the Russians have 2,000 to 10,000 tactical neutron bombs and we have none, our "strategic balance" of ICBMs etc will be incredible retaliation, so our tactical deterrent "gap" in defenses puts us into the situation that Kennedy forecast.)
Kennedy's 1961 decision to back Kahn's crash civil defense program was apparently due to his attending the June 1959 nuclear war hearings (at which Herman Kahn first found fame); yet even earlier Kennedy had observed first-hand the appeasement of the Nazis while working for his father, the US Ambassador, for 6 months in 1939, writing his 150-pages thesis on "Appeasement at Munich: The inevitable result of the slowness of the British democracy to change from a disarmament policy"! This thesis was edited into the 1940 UK bestselling book "Why England Slept" by the New York Times journalist Arthur Krock (with a foreword by Henry Luce), in which Kennedy pointed out that the refusal of pro-disarmament northern left-wing councils to instigate civil defence (then called air raid precautions) supported fascist appeasement! However, Kennedy's interest in arms race, disarmament, and war issues goes back even further, to the year 1932, when he was 15 and in hospital, according to the author Kay Halle: "Joseph Kennedy Sr asked me if I would stop with him while we were in the hospital to see his young son who was in there quite ill. ... We went into his bedroom, his room at the hospital, and you could hardly see him, he was so buried in the bed under masses of books. ... I was awfully interested because the book he was reading was World Crisis by Winston Churchill [the book recommended as the best study of war and deterrence and its failure, by Herman Kahn in On Thermonuclear War]."
(Kay Halle quote source: Robin Cross, "JFK: A Hidden Life", Bloomsbury, London, 1992. Robin Cross's JFK book also points out that Kennedy "had always been a supporter of a vigorous defense policy. In 1948-9 he had attacked the Truman administration over the economies it had made in the defense establishment, advocating an air force of 70 groups, rather than the 55 groups proposed ... in the 1950s, he had urged the re-arming of Europe, if necessary with US help ... In the Senate in the summer of 1954 he had opposed the Eisenhower administration's reduction in the size of the army ... In May 1955 ... he claimed that the administration had 'guessed short' on the military strength of the Soviet Union ... It was by this consistent route that in 1958 Jack Kennedy arrived at the momentous discovery of the 'missile gap', which was to provide one of the principal themes of his 1960 presidential campaign." Kennedy was on the same page as Kahn. In 1957, America had no proof-tested ICBM, just the 3,000 mile range Jupiter IRBM, while the Russians had successfully tested ICBMs the rockets of which successfully launched the first satellite, Sputnik, on 4 October 1957. Although by putting Jupiter IRBMs into Turkey America could cancel out the small ICBM "missile gap", there was concern that just a few Russian ICBM nuclear blasts over American cities could wipe out Western Cold War resolve, as had happened at Hiroshima and Nagasaki. When elected, Kennedy reversed Eisenhower's civil defense policy, as well as increasing the Minuteman ICBM order by 75%, the Western Europe tactical nuclear weapon stockpile by 60%, and the total number of American nuclear weapons by 100%, in an early effort at bankrupting the Russians with an arms race; a policy abandoned for a time after the Vietnam disaster, but re-instigated in the 1980s by Reagan with the desired effects.)

"People May Not Care Simply Because They Do Not care. ... The following (paraphrased) quotations are typical of the bureaucrat or decision maker who simply cannot imagine that his safe, snug world can really be dangerous. (The quotations are not exclusive. The determined do-nothing advocate will go through each in turn.)
1. The problem is hypothetical. You cannot prove that it exists. There is no need to get hysterical.
2. The problem is there, but there are many other problems. In your parochialism [limited views] and naivety, you have gotten hysterical. We have known about this problem for some time and we are not excited. Why are you?
3. The problem is there. It is insoluble. (Or, it is too late to do anything.) For God's sake don't rock the (political or public relations) boat. [This is based on Kahn's dealings with people like his boss at RAND Corporation, just prior to his leaving to found the Hudson Institute.]
The key words in the above are hypothetical, parochial, naive, and hysterical. That is, any specialist who raises a problem in his specialty is accused of being hypothetical and parochial, of not taking a practical over-all view. ... I can remember an occasion when I was discussing with one of these critics what seemed to me like a problem approaching potentially crisis proportions. He insisted that I was comparing hypothetical Soviet programs with hard American programs. I pointed out with some asperity that the Soviets up to that time had refused to allow our staff access to their records; naturally we would have some trouble proving that these programs existed and would actually meet the hypothetical dates. On the other hand, our staff did have access to U.S. data, so it was easy to show that our counter programs were not as firm as advertised. ... A typical hypothetical possibility is illustrated by the ominous possibilities for Hitler-type blackmail tactics created by the waning of our Type II and Type III Deterrence capability" - H. Kahn, On Thermonuclear War, pp347-8.
"There is a great deal of worry today that the Russians may make impressive gains utilizing only 'ambiguous challenges', without presenting us with any direct challenges. ... Their success to date in using 'ambiguous challenges' should be nothing to what they could do if they could afford and desired to be unambiguous. ... I think we can expect much firmer, confident and imaginative behavor, if not audacious and reckless conduct, from Khrushchev and his successors that we had from Stalin [a prediction that was confirmed by the 1961 Berlin Wall, 50 megaton test and the 1962 Cuban missiles crisis, etc.]" - H. Kahn, On Thermonuclear War, 1960, p348
"As the picture of horror of a modern thermonuclear war grows, we tend to ... we emphasise the impact of our capabilities on the enemy's mind rather than on his body [italic emphasis is Kahn's own]. ... Type I Deterrence is the deterrence of a direct attack [Dulles' massive retaliation]. ... Type II Deterrence is defined as using strategic threats to deter an enemy from engaging in very provocative acts [e.g. invasion of Poland 1939, invasion of Belgium 1914, invasion of Ukraine 2022] ... Type III Deterrence might be called 'tit-for-tat' [e.g. Kennedy's decision to resume USA nuclear tests in 1962 in response to Russia's 50 megaton test in late 1961, etc.]." - Herman Kahn, On Thermonuclear War, 1960, p126. Regarding "knockout blow" propaganda scams in the media/politics, Kahn on p350 argues that the same delusional lie occurred before each major war, including WWI and WWII, both to sell the war to the public and to justify not planning for a long-duration war of attrition which seemed "defeatist". For example, mass media "pacifist" morons believed and hyped that, prior to WWI: "interdependence of nations was so great that the sheer interruption of normal commerce would cause a collapse after a few weeks or months in much the same way that people argue today that if the A country (big cities) is destroyed, the B country (small cities, rural areas) must also necessarily collapse [after a countervalue nuclear strike on cities]. Therefore, almost everybody expected the war of 1914 to be short ... the famous Schlieffen Plan ... called for them to destroy the French in about 6 weeks, then move their army to the Russian front and destroy the Russians in the next few weeks... [Hitler in 1939 simply aimed to repeat this, dismissing Schlieffen Plan's failure in WWI as sabotage from internal enemies of the state]." (Quote from Kahn, OTW, p350.)
"To understand this attitude ... in 1961 Herman Kahn’s 1960 radically innovative book on the nuclear deterrence of war in general (not merely “massive retaliation” to deter all-out “doomsday” attacks, as was the previous policy by Dulles) was “reviewed” by controversial lawyer James Roy Newman in Scientific American. Newman, a complete bastard to Britain - he drafted the notorious and paranoid McMahon 1946 US Atomic Energy Act, which illegally and unilaterally ended Britain’s wartime agreement to continue postwar collaboration on nuclear energy - hadn’t read Kahn’s book (any more than he had read the vital Churchill-Roosevelt Hyde Park agreement for post-war continuation of nuclear collaboration of September 19, 1944 or consulted the UK government on the topic, when drafting the quack Atomic Energy Act passed by Congress in 1946!), and just scanned the first part of Kahn’s On Thermonuclear War briefly and taken some quotes and tables out of context to criticise (despite the title, its purpose is the credible deterrence of major provocations, not just the fighting of WWIII if deterrence fails). Moreover, he denied the existence of the author, because the publisher hadn’t provided much biography! We don’t need that kind of abuse from such bigots, do we?" - https://nigecook.substack.com/p/coming-soon

The explanation of the neutron bomb's invasion deterrent history in the 1958 low yield relatively clean "peaceful" Livermore nuclear explosives Dove and Starling is given by Samuel Cohen in his 6 December 1984 interview, conducted by Robert Del Tredici in Beverley Hills, California (published on pages 157-9 of his 1987 book, At Work in the Fields of the Bomb,):
"I was in the Efficiency Group at Los Alamos. Our job was to figure out the yield of the bomb that was burst over Nagasaki. ... On the evening of Hiroshima, when Oppenheimer was describing in very crude terms the catastrophe that had taken place over that city, the scientists who were listening to him were a bunch of howling savages, embullient beyond imagination, as pleased as punch ... Oppenheimer is rightfully called the father of the atomic bomb, but equally rightfully he could be called the father of the tactical nuclear weapon because he did the first conceptual spadework for using nuclear weapons strictly in a battlefield way instead of just decimating cities in a holocaust [thus led to his legendary dispute with Teller who just wanted massive retaliation H-bombs as a deterrent and bargaining chip for peace with Russia] ... He professed to be sufficiently guilt-ridden and aghast and appalled over the bombings of Hiroshima and Nagasaki that he never wanted that to happen again. So he recommended we design lower-yield weapons that wouldn't wipe out cities ... The basic concept is to be able to have a battlefield nuclear weapon that won't have all these nasty side effects ... If it's going to be used to get what we call the 'separation of effects', in other words, to get rid of the blast and heat [collateral damage to civilians], it not only has to be air burst, but it has to be burst high ... between 2,000 and 3,000 feet. ... it's a kind of micro-mini hydrogen bomb. ...
"I'd had the idea for the neutron bomb about 8 years before I figured out how to put it together. I put together the actual concept in the summer of 1958. It came about purely by accident when I visited the Livermore Laboratory in the spring of 1958. I asked if anyone had any new ideas going around, and they said they really didn't, though they had begun work on some peaceful nuclear explosives. And the head of the division said, 'Before you go home, you ought to take a look at these', and he showed me designs for some of the peaceful devices. And there they were: the neutron bomb characteristics. One of those designs was called Dove. Dove, by the way, for 'Dove of Peace'. ... Well, there were two, Dove and Starling; both derived the major share of their energy from fusing deuterium and tritium. ... The question I asked was, 'How many neutrons come out of this thing?' They made a few back-of-the-envelope calculations and the answer was: a hell of a lot. Then I took these calculations home and made my own calculations about the military effects of such a weapon, and, voila, the neutron bomb! Then I put together the military concept of how to use this bomb and went off on a big sales campaign. ...
"Ever since Day 1 we've patterned our nuclear war-fighting strategies after Hiroshima and Nagasaki. ... So what we're basically proposing here [using conventional Teller or Dulles "massive retaliation" MAD mutual-assured-destruction H bombs-on-cities crap] to deter war is the threat of our own suicide. ... it's all based on the premise that if we cross that nuclear threshold one more time, we'll bring on the beginning of the end. So you get people like Jonathan Schell [author of "Fate of the Earth" which lies that the 15 megaton Bravo test blinded everyone at Rongelap and that radiation can't be stopped easily by simple earth covered shelters proved at nuclear tests] and Carl Sagan with the idea of nuclear winter and everything else. It's Armageddon. I don't find their ideas credible, and I'll tell you why: because in order to get these results from using nuclear weapons against cities, you have to have nations willing to use them that way. ... You know what the United States has to do if it wants to survive? It has to accept the fact that there will probably be a nuclear war, and it has to prepare to fight it and win it. ... It's been U.S. national policy for more than a quarter of a century that nuclear weapons are actually unusable weapons. That's horseshit, and you can quote me on that. ... Let the allies develop their own neutron bomb. As a matter of fact, let's sell it to them! They should have discriminate weapons for their own self-defense. The United States doesn't need to take on the burden of defending all the rest of the world. That [the UK policy of 1914 regarding Belgium's invasion and 1939 regarding Poland's invasion, not to mention 2022 regarding Ukraine's invasion] is in fact the best way of getting into a nuclear war ..."
The technical history of Livermore's development of enhanced-neutron tactical nuclear weapons goes back to a study of lightweight, thin H-bomb casings by Dr Herbert York, discussed in detail below with regard to recently declassified data on the designs of two American H-bombs of roughly similar physical size but different mass, composition and yield: the W47 and the B28. York showed that the pressure and duration of the x-ray energy coupling causing the fusion stage's compression force are both functions of the case thickness. So if you reduce the outer casing thickness to make the bomb lighter, you have less compression force and it lasts a shorter period of time. To ensure a successful fusion burn in this situation, you have to reduce the amount of dense material like uranium in the fusion stage and replace it with easier to compress fusion fuel. This occurred in progressive Livermore designs with smaller sizes and lighter casings during the 1950s, starting with a device called Linda, then Flute, then Piccolo. These had thin oralloy (highly enriched U235) pushers (3.8mm thick for Piccolo), but clean versions with lead pushers in place of U235 were designed, and the combination of the high percentage of fusion yield with the thin pusher and outer casing gave the enhanced neutron Dove design.

"Foreign politics demand scarcely any of those qualities which are peculiar to a democracy; they require, on the contrary, the perfect use of almost all those in which it is deficient. ... a democracy can only with great difficulty regulate the details of an important undertaking, persevere in a fixed design, and work out its execution in spite of serious obstacles. It cannot combine its measures with secrecy [spying problem plus whole notion of democracy requiring voters to be informed] or await their consequences with patience. These are qualities which more especially belong to an individual or an aristocracy; and they are precisely the qualities by which a nation, like an individual, attains a dominant position. ... The mass of the people may be led astray by ignorance or passion ..." - Alexis de Tocqueville's Democracy in America 1835 (Vintage NT 1954 ed, v1, pp243-5, as quoted by H. Kahn, OTW, p579; note that Kahn's full quotation backs the notion of elitism aristocracy as the solution, aka the clan dynasties in USA politics such as the Kennedy and Bush political families. On page 407 of OTW, Kahn also appears to back elitism in discussing how von Mannstein was able to bypass jobsworths in the General Staff and get a direct meeting with Hitler to modify the Schlieffen Plan's to outflank the new French Magoniot Line defenses by invading through the Ardennes Forest with the latest Panzer tanks; Hitler had many defects but at least he was prepared to listen seriously to "crackpot" sounding ideas from the lower ranks and implement them, unlike so many openly fascist "top dogs" today).
"There seems to be little point in discussing the view that finds a solution in a totally disarmed world. ... The violator would then have an incredible advantage if the agreement ever broke down ..." - Herman Kahn, On Thermonuclear War, Princeton Uni. Press, 1960, page 5. Kahn adds added that the world of 1914 and 1939 was non-nuclear, there was an international ban on chemical weapons (the Hague Convention of 1899) prior to WWI in which chemical weapons were used without restraint, and that there was agreement amongst experts that WWII would start with a gas knockout blow against cities, when in fact no gas was ever dropped on cities during WWII (pesticide Zyklon B, crystals which emits non-persistent hydrogen cyanide gas on exposure to the air, was used in gas chambers but the Nazis never dropped any of their 12,000 tons of tabun nerve agent on cities thanks to retaliation risks and the universal issue of gas masks). So disarmament propaganda was just that, lying blathering by politicians to earn "peace prizes".
"It would be disastrous to have a conspicious gap in the spectrum of deterrents and capabilities [strategic and tactical to cover all kinds of dangerous provocations]. For example, when President Eisenhower remarked at a press conference that it was unthinkable that he would call out federal troops to enforce federal law ... some Southerners immediately did something to make it thinkable [Eisenhower ordered the 101st Airborne Division of the U.S. Army to Little Rock's Central High School to reinforce Arkansas' National Guard in allowing 9 black students to enroll at the school in 1957]." - Herman Kahn, On Thermonuclear War, p286. The point is, saying something is "unthinkable so we don't need to prepare for it" is not cost-effective when it encourages and invites the enemy to invade and provoke you. Lying blathering peacenik enemy collaboration always backfires by inviting aggression. (Even Trump had this problem, when some of his supporters misinterpreted his peaceful speech - questioning why the postal ballots showed higher support for Biden than the polling station in-person votes - and invaded the Capitol on 6 January 2021.) If you want to deter evil, you have to avoid ambiguity and to be open and also clear that nothing is "unthinkable" and state in advance precisely what you will do in any eventuality, so as to make deterrence unequivocally effective. You want the enemy to be clear what they will have coming to them if they provoke you: "with the record of the 1930s plainly before us, we should all be able to realise that it is possible for all these kinds of deterrence to be strained." - Kahn, OTW, p286.
No wonder the Leninist lawyer James Roy Newman of the "elitist communist" Scientific American hated Kahn in his "review"! I first read Kahn's On Thermonuclear War in 1990, and have just finished re-reading it in September 2024 due to the Ukraine war. My view of the book is now very different to the notes I made in 1990 when reading Kahn during the writing of my own unpublished August 1990 dated manuscript Nuclear Weapons Effects Theory. The basic problem is that Kahn has two theses in one volume. The first 310 pages of On Thermonuclear War debunks populist nuclear weapons and war myths, such as fallout gamma rays and strontium-90 in food killing everyone; the second part, pages 311-651 is an analysis of the history of war and extrapolations of that history to various kinds of deterrence and nuclear war. As his preface says (page x): "This book is dedicated to the goal of anticipating, avoiding, and alleviating crises." (Italic emphasis is Kahn's own.) The problem with Kahn's On Thermonuclear War is precisely the same as that with Glasstone's Effects of Nuclear Weapons: jumbled up presentation (if you are discussing one type of nuclear explosion, you need to discuss the effects that type produces, not separate effects into different chapters, so readers are misled and think heavy fallout occurs from air bursts, etc.,) and you need to show how deterrence of certain kinds of nuclear attack even within a nuclear war is necessary to retain "bargaining chips", "cities as hostages", etc. Otherwise 100% of readers do what journalists do with "Nukemap" and simply assume the entire enemy stickpile is used in a single knockout blow on cities, in which 100% of people unprotected, by even "duck and cover"! This increased casualties by a factor of 120 in Hiroshima, and is where you get the 120 fold exaggerations of nuclear war casualty predictions from. By the omission of key (secret classified) data on neutron bombs to deter invasions in the first place, or survival of people and vehicles in simple, cheap trench shelters at nuclear tests, for example, you depart 180 degrees from reality.
"But how many murders are they [lying journalists, politicians, fellow-travelling Western nuke designers who won't disclose the truth to the media] responsible for? Basically, nuclear deterrence using tactical nuclear weapons to deter the invasions that set off both World Wars, i.e. the invasion of Belgium in 1914 by concentrated force and of Poland in 1939 by concentrated force (from the East by Russia and from the West by Germany), could have prevented many millions of deaths since 1945, but evil folk prevented this, wanting war to continue. ... Hiroshima was entirely vaporized by a nuclear explosion on 6 August 1945, says CND. In that case, this US Air Force film of the slight scorching on otherwise undamaged materials, proving the effectiveness of “duck and cover” for shielding, is fake news. But it’s not. What’s fake news is everything every published on nuclear weapons effects by Bulletin of Atomic scientists, Scientific American, all newspapers, and all TV shows on the subject ... In fact, Hiroshima casualty data published [in the massively-effects-exaggerating] Glasstone book “The Effects of Nuclear Weapons” (1962-77 editions) proves that being indoors in the lower floors of a concrete building reduces the LD50 radius from 1.3 miles in the open to 0.12 miles for lower floors of concrete buildings. Since area is proportional to radius squared, this means a protection factor of 120 for Hiroshima burst conditions (16 kt, 600m altitude). This shielding factor would for a densely populated modern city reduce 500,000 (half a million) killed for people outdoors totally unshielded to “just” 4,000 killed indoors on the lower floors of modern city concrete buildings! Er, this result of 4,000 killed just happens to be precisely the number mentioned by the Independent newspaper article (quote above!) of pensioners murdered by cold and starvation due to financial destitution due to Sir Keir Starmer’s “tough decision” to end winter fuel allowances, in order to pay massive salary rises to public sector employees." - https://nigecook.substack.com/p/another-assassination-attempt-on
Kahn makes a further essential point about "secrecy" (there ain't any secrecy when the other side has spies like Fuchs) covering up alleged gross delusional failings in Western nuclear weapons design, effects and capabilities on page 384 of On Thermonuclear War, where he quotes extensively from chapter 6 "Torpedoes" of Rowland and Boyd's US Navy Bureau of Ordnance in World War II (published by the US Navy), proving how the secrecy of US torpedo design, development, testing and stockpiling led to tragic groupthink delusions of supremacy and of having the best torpedoes in the world, that were only debunked in actual combat during the 1941-3 period of WWII: "As each defect was exposed, the morale of the submariners who risked their lives to take the war to the enemy suffered, the enemy was given further respite ... the problem was compounded by the Bureau's reluctance to accept the fleet evaluation of its weapon. This reluctance was born ... from misplaced confidence in its own past work. ... Security, a necessary concern of the armed forces, became such a fetish that measures designed to protect a device from enemy eyes actually hid its defects from those who made the regulations. Ironically, some of those defects were already known to the foreign powers who later became our allies or enemies. ... even when the torpedo exploded properly, it lacked the punch submariners desired. ... each defect concealed another ... The Bureau was reluctant to believe that the secret weapon long regarded as one of our greatest assets should turn out to be a liability." (Kahn gives many other similar examples of bureaucratic secretive nonsense backfiring even in WWI, in Chapter 8 of OTW. American Colonel Billy Mitchell of the American Air Force was the first to suggest paratroopers to get over enemy lines, and predicted a Japanese attack on Pearl harbor (he was demoted and then court martialled on the direct orders of President Calvin Coolidge). Tanks and gas are both treated in detail by Kahn: both were kept so secret that the military didn't have a clue about them when first used on the battlefield so their initial "factor of surprise" was lost and the enemy was given the chance to negate them after bungled first-use:
"The first use of tanks in September 1916 completely ignored the tactical and strategic ideas of the innovators and was carried out as a sort of field trial. ... The German poison gas story has some interesting analogies with the British tank story. This too had an uphill fight with the authorities. Again, even after the weapon had been developed the command did not wish to take the risk of using the untried weapon on a large scale, though the inventors urged it, until the military had developed some experience on the capabilities and limitations of gas warfare. It was first tried on April 22, 1915 and proved a tremendous tactical success. In fact, a five-mile gap was opened in the Allied lines, but the Germans were not prepared to exploit the opportinity. They were not really making an attack, they were just trying an experiment. The British reaction ... was very fast. ... Sir William Ramsay had guessed from the description of the battle reports that chlorine had been used and came to the War Office with a protective measure, some sample mouth-pads made of flannel or wool soaked in hyposulphite of soda. British women were asked to furnish 1,000,000 at once. Thanks to their help and Red Cross efforts, the necessary quantity came in several days. Within a fortnight, every man in the British army at the front was supplied with a rudimentary respirator. ... History is full of examples of impractical notions, or, equally important, notions that proved to be just fine but which were tested prematurely. ... The most spectacular military event of World War I, the development of two parallel lines of trenches ... while predicted by Bloch, came as a complete surprise. ... given the examples of such warfare in the American Civil War and the Sino-Japanese War - it is hard to see how military experts could have overlooked the possibility that the widespread availability of machine guns and barbed wire might result in static trench warfare, but the military planners on both sides completely overlooked the possibility [as they did for submarines blocking logistics supplies, depth charges, and particularly SAS type infiltration tactics to overcome trench warfare: French Captain Laffargue wrote a proposal for this which the Allies laughed at, but when a copy of the proposal fell into German hands, Ludendorff at once (quote from Captain G. C. Wynne on p357 of Kahn's OTW): "translated into German and issued as an official German training manual, eventually becoming the basis of General Ludendorff's textbook ... [leading to German implementation of the enemy's plan so] the Germans so effectively broke through the British position in March 1918, and the Chemin des Dames position in May ...". SO, UNLESS WE ARE TO REPEAT SUCH MISTAKES, WE MUST NOT ALLOW PETTY HUBRIS OF "JOBSWORTH BUREAUCRATS" TO BLOCK INNOVATIONS NEEDED TO WIN WARS!
ABOVE: Kahn was treated with the "shoot the messenger" reaction against Machiavelli, merely for speaking truth to power in 1960: "If the above deterrents are to work reliably, there must always be in the background the knowledge that if they did not, other kinds of deterrents or corrections would come in. It could be disastrous to have a conspicuous gap in the spectrum of deterrents and capabilities. For example, when President Eisenhower remarked at a press conference that it was unthinkable that he would call out federal troops to enforce federal law in the Southern states, some Southerners immediately did something to make it thinkable. Something similar may happen if he convinces the Soviets that he means what he says when he says that "war is preposterous." I suspect that many in the West are guilty of the worst kind of wishful thinking when, in discussing deterrence, they identify the unpleasant with the impossible. It is particularly hard to understand why this is so when almost all who write on this subject were adults during the later part of the Hitler era and presumably were educated in some of the ways in which all these types of deterrence can be strained." - Herman Kahn, On Thermonuclear War, page 286. Will the left ever learn facts from history?
ABOVE: Nazi supporting "peace" propaganda flooded the UK and USA in the 1930s, as it still does. Comintern's legacy is a repetition of the 1920s and 1930s anti-deterrent mindset, falsely portrayed by Russian "Fifth Column" propaganda fronts as "pacifism" or "peace" arguments. When communists were rejected as unpopular at the election polls, they adopted subversive methods, trying to undermine war readiness (deterrence) to help Russia get in a position to start WWIII, just as they had helped the Nazis in the 1930s do exactly the same thing (while being awarded "Nobel Peace Prizes" for their propaganda; look at the history of 1920s and 1930s gas war anninilation "Nobel peace Prize" liars Lord Noel-Baker, Sir Norman Angell et al.). The result wasn't an end to the arms race or militarism, but an escalation on the enemy side, and an erosion of technical competence and military preparedness on the side of the democracies. Banning the TV transmission of classic "Tom and Jerry" cartoons for "portraying violence as normal to kids" and banning "Action Man" style toy guns for "encouraging deterrence of dictators to kids" in the West, didn't stop Russia's Hitler Youth movement from preparing for war. All this just helped the enemy prepare for WWIII. The paranoid conspiracies aren't the supposed "war mongers" on the side of the democracies, but by the real war mongers on the side of the dictatorships and their fellow travelling "Sputniks", in infiltrating the Western political systems, mass media, and educational establishments with delusional fanatical anti-Western-nuclear bias. Numerous articles sent to "New Scientist" in the 1990s proving the errors in popular propaganda it published by anti-nuclear fanatics like "Rob Edwards" (co-author of the 1982 book "Fuelling the nuclear arms race: the links between nuclear power and nuclear weapons") were simply rejected because they contradicted populist lies "New Scientist" published weekly from such people! This made it appear that there was no opposition to such Russian Fifth Column propaganda lies! Result: no civil defence option and no tactical nuclear deterrent option against "Iraq's Weapons of Mass Destruction" in 2002, and instead WAR. Which is precisely what these lying thugs want. Once the press, the teachers, and the corrupt pseudo-liberal MPs or Lords use enforced "speech filtering" to completely corrupt free debate (it's not that much different to a dictatorship, except that "no platforming censorship" is used in the West, while bullets and poison is used in the dictatorships), you have crackpots and quacks in charge of "democracy", which is a travesty of the term!
If you ban civil defense and nuclear deterrence of dictatorships, then you are left only with the option of WAR against every invasion or WMD threat which your delusional censorship encourages and promotes!
That's not pacifism. On the contrary, it's needless fascist based genocidal war that could be stopped!
As regards "child soldiers": we're constantly reminded of the plight of kids in wars, so why should they be denied the right to defend democracy in countries with ageing populations, when a failure of deterrence and dictatorial occupation will ruin the lives of kids?
All these fanatically anti-civil defense, anti-deterrent so-called "pacifists" - when pressed for their solution to terrorism - claim we can use "non-violent opposition" to enemy attacks; but we saw what happens to kids in this situation in the Holocaust and wars! If we're not going to have a nuclear deterrent, and we're not going to allow kids to learn how to protect themselves, the results are evil and immoral. These facts are conveniently declared to be "taboo"!
KEY FAILURES OF TODAY'S "MINIMAL DETERRENCE" (KAHN'S "TYPE 1 DETERRENT"):
1. It doesn't deter world war situations, which both occurred because of invasions of 3rd parties (invasion of Belgium 1914, Poland 1939), akin to the 2014 and 2022 invasions of Ukraine by Russia. In other words, you need credible deterrence of major provocations.
2. It doesn't even deter a direct attack by fanatical opponents, such as the October 2023 Hamas surprise attack on Israel or the December 1941 Pearl Harbor surprise attack or the 9/11 attack by war-crazy thugs.
3. It assumes sanity on the enemy side, while mental pressures are brought to bear on the sanity of the opponent in response to major provocations, e.g. "sanctions" against the enemy hardens their resolve (aided by internal state propaganda of the enemy, blaming hardships on you), just as "pressure" such as napalming Vietnam failed to deter the Tet Offensive. If you ban your use of overwhelming force to credibly stop or deter an opponent, you don't end in a fairy tale land of mutual love and understanding, but with a battle-hardened opponent, with the fighting mentality of a wounded animal. In other words, you get the opposite result.
4. The only people who can be safely and credibly deterred with "minimal deterrence" are not terrorist states, but generally established democracies, who you don't have fights with anyway (see Dr Weart's "Never at War: Why Democracies will not Fight One Another"), so you've reduced deterrence down to a level where it's only credible in situations where NOT needed! Duh! Try explaining this with any hardened fanatical "pacifist" and you soon see they're fanatical ranting lunatics obsessed with moronic "taboos" or war-making eugenics pseudoscience genocide schemes, and not the least interested in what they claimed they're concerned with, PEACE!
"... in letters to me dated April 10, 1979, and June 18, 1979, representatives of the DOE stated that my open research, and a national contest that I conducted, would lead to the generation and transmission of classified data - this in spite of the fact that all of the information that I was seeking would come from unclassified published sources. It has also become obvious that at least one of the three concepts discussed in the disputed Morland article is currently unclassified in the Soviet Union, and that when it was discussed openly here in 1976 by a Soviet scientist, the U.S. government, acting through the Energy Research and Development Agency, classified his speeches (Morland might have stood a better chance of publishing his article in the USSR).
"The concepts discussed in the Morland article deal with basic applied physics, and they are certainly no longer 'secret' - if they were, four other nations would not now have operating thermonuclear weapons. Even though the DOE now admits that this type of information is in the public domain, it is still trying to suppress the circulation of this data, in order to maintain a false illusion of secrecy, and to maintain a real monopoly over the dissemination of weapons-related information, and over the public discussion of American nuclear policies, policies which affect nuclear reactors as well as nuclear weapons. ... What happened next will be discussed in the description of the accompanying diagram, when the concept of isentropic compression is explained. ... As can be seen from the enclosed diagram, the basic bomb consists of two boosted fission triggers at opposite ends of a mass of lithium-6 deuteride fusion fuel, all contained in an outer casing of uranium-238. ... This arrangement requires that the outer weapon casing play an essential role (as medium to absorb x-rays and re-emit them into the fuel mass) ... there are two triggers in the bomb. The purpose of this is to allow a symmetrical compression of the fusion fuel between them, as well as allowing an x-ray source at each end of the bomb. These two fission triggers must fire simultaneously, or no fusion will occur. ... This sudden elevation in temperature of the fusion fuel, following the isentropic compression, begins the larger main fusion reaction in the weapon. ... " [Emphasis added.]
It must be emphasised (see the latest blog post here for the physical and mathematical details) that adiabatic "non-shock isentropic compression" of low density fusion fuel was first suggested during the April 1946 Los Alamos Super Conference, but was ignored by Teller and the American mainstream until investigated and tested by Nuckolls during totally clean secondary tests (including a 99.9% clean Ripple II 10 megaton test on 30 October 1962). Isentropic compression is compression without heat transfer between the fusion fuel and its surroundings, involving a gradually increasing compression - more like the pressure variations in a sound wave than the pressure discontinuity at a shock front. Shock waves involve "isothermal compression" at the shock front, which radiates wasted energy as heat in all directions, reducing the kinetic energy used to compress the fusion fuel. The key thing to focus on is the fact that you want to compress fusion fuel to cause fusion, and the fusion then releases heat which opposes compression, dispersing the remaining fusion fuel, and ending fusion. What you are trying to do is to compress fusion fuel so it releases nuclear energy (including heat) as a result of nuclear fusion, not waste energy radiating heat into the surroundings before you compress the fuel (such heat waste opposes compression of the fusion fuel). To the extent that you heat the fuel and cause it to radiate energy during compression, you defeat your purpose and get an inefficient compression (akin to pre-initiation in primary stage fission weapons if they are pre-heated by neutron induced fissions).
Teller ignored all this, and indeed until March 1951 he claimed to have a "no go theorem" against compression, and then he used ablative recoil exploding pushers to give relatively ineffective shock compression of fusion stages in his "Sausage" design, the standard 1950s thermonuclear system. Nuckolls and the Russians, however, used gentler isentropic compression (by using a low-density pusher like beryllium on a clean LiD fusion fuel capsule; with any dense U238 placed in the outer casing of the bomb, rather than used as the pusher in contact with the fusion fuel), which enabled more of the primary stage x-ray energy to be used to compress the fusion stage to high density, with less energy being wasted on heat transfer during compression. If you do any sort of work, e.g. hammering nails into wood, charging a battery, or running an engine, some energy will be used in achieving the objective, and some will be wasted as heat. If you want maximum work efficiency, you need to minimise waste heat (i.e. you want to reduce the rise in entropy S, so that the change in entropy dS ~ 0, which is the definition of the ideal of "isentropic compression"), which means losing the shock wave-producing dense ablative shell on the fusion fuel in the "Sausage" designs tested in the 1950s by the USA, which resists isentropic compression. With a dense pusher, you get shock compression which radiates heat before the shock even reaches the core and compresses it, so you only get core compression factor of 20-30, whereas if you use a low-density ablator like beryllium, aluminium or plastic on the fusion fuel, you can achieve nearly isentropic compression factors of 1,000 or more! I.e.. the core density is increased by a factor of 1,000, so that the fusion rate is much faster and more efficient (more fusion is accomplished before the bomb blows itself apart). The latter compression is even sufficient to ignite deuterium fusion, according to Russian claims about their 1960s-1970s cleaner isentropic bomb tests for "peaceful uses" (and tactical nuclear weapons), giving a far cheaper and longer-life warhead than the deuterium-tritium fuel used in the low yield American "Dove" and "Starling" designs of neutron bombs! ("Isotropic compression" just means equal from all directions, and has nothing to do with "isentropic compression".) Similarly, the first implosion bombs used dense U238 neutron reflectors around the core, requiring inefficient shock compression, whereas lower density beryllium reflectors allowed greater efficiency quasi-isentropic compression in fission designs.
A great deal of the popular media's confusion over thermonuclear weapons designs is down to misunderstanding the nature of the x-ray pulse from the fission primary stage. Glasstone and Dolan's 1977 Effects of Nuclear Weapons usefully explains that most (over 80%) of the energy can be released x-rays generated by inelastic fission fragment collisions, on a time scale of the order 1 shake or 10 nanoseconds. However, that is only true for a bare fissile metal core, so in reality the considerable mass of chemical implosion debris (mainly carbon, oxygen and hydrogen ions) around that core diffuses the x-rays with a random-walk that slows the x-ray emission into typicaly a 100-times longer pulse than 10 nanoseconds, i.e. around 1 microsecond. It is for this reason that early thermonuclear weapons had heavy outer cases, to contain the diffusive x-ray emission pulse from the fission primary stage's ionized low-Z element fireball, enabling more of that energy to be coupled into fusion stage before the outer casing is destroyed and the coupling ends. Because of this, the fusion stage is not abruptly compressed over a 10 nanosecond time period as implied by Glasstone's unclassified statement that most of the fission energy is emitted in the last shake, but more gradually over a time of up to 1 microsecond. The design of the fission primary stage therefore determines the nature of the x-ray pulse waveform. This problem has been known since the beginning, which is why a gun-type fission weapon was selected in 1946 for the fusion "Super" primary stage, because it would eliminate the implosion debris fireball x-ray diffusion problem, and also why Gamow designed a cylindrical implosion "Greenhouse-George" primary, to enable x-rays from a bare side of a fissile core to initiate fusion without the complexity of x-ray shielding and transport through low-Z barriers, as occurs with spherical implosion primary stages.
Ironically, Chuck Hansen, the author of US Nuclear Weapons, re-invented the Russian "Project 49" double-primary H-bomb independently in a 27 August 1979 letter to Senator Charles Percy of Illinois, only to have this double-primary design dismissed as "wrong" by American nuclear weaponeers, some of whom didn't even know that: (a) Teller and Ulam had stated that one or more primary stages could be used to ignite a H-bomb in their 1951 breakthrought paper, and (b) you can get both primary stages to detonate simultaneously by simply wiring up the electronic neutron guns for each primary into a parallel circuit, and doing the same for their electrical detonators and x-unit capacitors and krytron switches. Hardened groupthink dogma orthodoxy is is hard to debunk! (The Russian double primary idea was even earlier suggested by journalist John McPhee to nuclear weaponeer Dr Ted Taylor with this dismissive result, as reported in McPhee's 1974 book, The Curve of Binding Energy. Note that Howard Morland's design relied on Edward Teller's single-primary H-bomb illustration in his article "Hydrogen Bomb", in the Encyclopedia Americana, v14.)
GEORGE GAMOW'S ASYMMETRIC-IMPLOSION FISSION BOMB DESIGN FOR USE AS AN EFFICIENT DIRECTED X-RAY SOURCE FOR RUSSIAN PROJECT 49 DOUBLE PRIMARY NEUTRON BOMBS
(a) the fissile mass is off-centre, so x-rays escape in a preferential direction with little shielding by chemical explosive debris, thus maximising the exposure of a fusion fuel capsule to x-rays from an implosion fission primary, and
(b) the fact
only one detonation point is required
(which can be shielded by a steel cover to protect that point from accidental impact etc), minimises the size of the x-unit capacitor, battery, etc, as compared to spherical implosions where a lot of points need simultaneous ignition for successful implosion (see French nuclear test flash x-ray photos below!). The West uses a "no-go theorem" to rule out this design called "one-point safety", whereby the implosion system must be safe from effective compression of the fissile core occurring from a detonation at any single point on the outside. However, for such very low yield (sub kiloton) fission weapons, safety concerns can be relaxed in a world war situation where mass production of nuclear shells is required, and the neutron gun must be fired at the optimum compression time to achieve a significant nuclear yield. The single point of detonation can be protected both (a) mechanically by a steel impact cap over it (so if dropped, any impact detonation will occur at the wrong point, and (b) electrically by a fuse in series with the detonator which will blow at a current rating below that required to fire the detonator. When the weapon's detonation is actually required, the fuse can be mechanically changed for a high-current conductor just before detonation.
A feature of this Gamow design is that although the off-centre fissile core is simultaneously compressed in time, the force is anisotropic (being naturally greater on the side with the most explosives), so the hollows in the fissile cores need to be displaced similarly to compensate (so that side of the fissile core with weaker implosion pressure is thinner). Although you would expect the ansiotropy of implosion to physically shift the core towards the fusion capsule and thus block the x-ray channel, this doesn't happen in reality because the time scale of the macroscopic acceleration of the core (taking many microseconds) is massive, compared to the relatively trivial timescale of the very fast nuclear reactions such as fission and x-ray ablation phenomena! It appears from Russian information that they use this kind of fission primary to massively reduce the mass and firing circuit complexity of their double-primary ignited neutron bombs. Dr Gamow illustrated technical reports himself, as he did for his wonderful kid's physics books on a big bang, etc.
ABOVE: note that a single Gamow asymmetric implosion fission stage can also be used to enhance the neutrons and prompt gamma rays in a preferential direction, for use in either ABM defensive neutron warheads (to take out incoming MIRV warheads), or to create a directed prompt gamma ray and prompt Compton current, for a non-lethal localized and directed EMP collateral-damage-averting nuclear weapon (as described using old tech, 3 decades ago in the November 1994 issue of Electronics World, by yours truly), and this Gamow off-centre implosion is depicted in an August 6, 2015-uploaded animated video and labelled "Swan" by Russian Wikipedia user "Guga50", which is currently displayed on the Russian Wikipedia article "Nuclear Weapons" (this Russian "Nuclear Weapons" Wikipedia article is not just a translation of the Western Wikipedia "Nuclear Weapons" article, which shows an entirely different "Swan"-labelled design; a symmetric prolate spheroid with 2-point detonation, not an asymmetric 1-point detonation implosive; my point here is just to point out a discrepancy rather than to say "one is right and one is wrong", since both types are certainly possible from the pure scientific standpoint and it is likely the American "Swan" design is the two-point implosion system, but the Russian Wikipedia design is backed by the design Western nuclear weaponeer Gamow explains in detail in his originally top secret 1946 report and the general Russian custom to take short cuts for cheapness that are "ruled out" by Western bureaucrats with bigger weapons budgets to blow at the taxpayers expense), which states: "... the 1st fission stage cannot provide a sufficient amount of X-ray radiation energy, which is necessary to ensure the explosion of "large" thermonuclear stages. In three-stage devices, the 1st fission stage (with an explosion power of up to tens of kilotons) is used for the radiation implosion of the 2nd ("small") thermonuclear stage (with an explosion power of several hundred kilotons), and the radiation of this 2nd thermonuclear stage (together with the radiation of the 1st stage) is used for the radiation implosion of the 3rd ("large") thermonuclear stage ... In "Tsar Bomba" (AN-602), the first two and the second two stages were placed symmetrically on 2 sides of the third ("large") thermonuclear stage, according to the so-called "bifilar" scheme." (Note: the Russian Wikipedia page on the neutron bomb points out that the casing is composed of "transparent" elements, i.e. those with small cross sections for 14.1 Mev neutron reactions, such as nickel, chromium and tungsten.)
Russian language Wikipedia https://ru.wikipedia.org "Nuclear Weapons" page, section on "Swan" (translated from Russian into English; 14 October 2024): "The described scheme of spherical implosion is archaic and has hardly been used since the mid-1950s. The principle of operation of the “Swan” type design (English: swan) is based on the use of a fissile assembly of a special shape, which, in the process of implosion initiated at one point by one fuse, is compressed in the longitudinal direction and turns into a supercritical sphere. The shell itself consists of several layers of explosive with different detonation rates, which is made on the basis of an alloy of octogen and plastic in the required proportion and filler - polystyrene foam, so that between it and the nuclear assembly located inside there remains a space filled with polystyrene foam. This space introduces the necessary delay due to the fact that the speed of detonation of the explosive exceeds the speed of the shock wave in the polystyrene foam. The shape of the charge strongly depends on the detonation speed of the shell layers and the speed of propagation of the shock wave in polystyrene, which is hypersonic under these conditions. The shock wave from the outer layer of explosive reaches the inner spherical layer simultaneously over the entire surface. A significantly lighter tamper is made not from 238U, but from beryllium, which reflects neutrons well. It can be assumed that the unusual name of this design - "Swan" (first tested by Inca in 1956) was suggested by the shape of the swan's neck. Thus, it was possible to abandon the spherical implosion and, thereby, solve the extremely difficult problem of sub-microsecond synchronization of fuses on a spherical assembly and thus simplify and reduce the diameter of the implosion nuclear weapon from 2 m in the “Fat Man” to 30 cm or less in modern nuclear weapons."
[Original Russian: "Описанная схема сферической имплозии архаична и с середины 1950-х годов почти не применяется. Принцип действия конструкции типа «Swan» ( англ. swan — лебедь), основан на использовании делящейся сборки особой формы, которая в процессе инициированной в одной точке одним взрывателем имплозии, сжимается в продольном направлении и превращается в надкритическую сферу. Сама оболочка состоит из нескольких слоёв взрывчатого вещества с разной скоростью детонации, которую изготавливают на основе сплава октогена и пластика в нужной пропорции и наполнителя — пенополистирола, так что между ним и находящейся внутри ядерной сборкой остаётся заполненное пенополистиролом пространство. Это пространство вносит нужную задержку за счёт того, что скорость детонации взрывчатки превышает скорость движения ударной волны в пенополистироле. Форма заряда сильно зависит от скоростей детонации слоёв оболочки и скоростью распространения ударной волны в полистироле, которая в данных условиях гиперзвуковая. Ударная волна от внешнего слоя взрывчатки достигает внутреннего сферического слоя одновременно по всей поверхности. Существенно более лёгкий тампер выполняется не из 238U, а из хорошо отражающего нейтроны бериллия. Можно предположить, что необычное название данной конструкции — «Лебедь» (первое испытание — Inca в 1956 г.) было подсказано формой шеи лебедя. Таким образом оказалось возможным отказаться от сферической имплозии и, тем самым, решить крайне сложную проблему субмикросекундной синхронизации взрывателей на сферической сборке и таким образом упростить и уменьшить диаметр имплозивного ядерного боеприпаса с 2 м у «Толстяка» до 30 см и менее в современных ядерных боеприпасах."]

Herman Kahn is clear, in On Thermonuclear War, about the mobilization problem for bulky conventional weapons (unlike compact nukes out of sight in subs, ICBMs or airfield igloos) triggering off wars such as WWI, quoting on page 359 the assistant chief of the French General Staff, General Boisdeffre's explanation to Russian Tsar Nicholas: "The mobilization is the declaration of war. To mobilize is to oblige one's neighbor to do the same. ... Otherwise, to leave a million men on one's frontier, without doing the same simultaneously, is to deprive oneself of all possibility of moving later; it is placing oneself in a situation of an individual who, with a pistol in his pocket, should should let his neighbor put a weapon to his forehead without drawing his own." Kahn also emphasises the ironic pacifism of the Liberal Party Cabinet of the UK Government which set off WWI by declaring war on Germany (which had not declared war on Britain and did not want war with Britain):
"The [August 1914 WWI-declaring British Liberal Party government] Cabinet was overwhelmingly pacific. At least three-quarters of its members were determined not to be drawn into a European quarrel, unless Great Britain were herself attacked, which was not likely. ... They did not believe that if Germany attacked France, she would attack her through Belgium [triggering WWI via the 1839 Treaty of London, an analogy to our guarantee to defend Ukraine in the 1994 Budapest Memorandum]..." - Churchill, The World Crisis, v1, Charles Scribner's Sons, 1923, p211 (quoted by Kahn, On Thermonuclear War, p387). Winston Churchill, himself a Liberal government minister when war was declared in 1914 (he had to rejoin the Conservatives after the Liberal Party was run-over by its role in declaring WWI) was anti-militarism expenditure in general, like his father Lord Randolph Churchill (who in 1886 resigned as Conservative Chancellor of the Exchequer, in an effort to reduce arms expenditure). On 13 May 1901, Winston Churchill, Boer War hero and newly elected Conservative MP, took up his late father's anti-militarism position in his speech to the House of Commons: "I regard it as a grave mistake in Imperial policy to spend thirty millions a year on the Army. I hold that the continued increase in Army expenditure cannot be viewed by supporters of the Government without the greatest alarm and apprehension, and by Members who represent working class constituencies without extreme dislike. I desire to urge considerations of economy on His Majesty’s Government, and as a practical step that the number of soldiers which they propose to keep ready for expeditionary purposes should be substantially reduced. ... Once you are so unfortunate as to be drawn into a war, no price is too great to pay for an early and victorious peace. All economy of soldiers or supplies is the worst extravagance in war. I am concerned only with the Estimates for the ordinary service of the year, which are increasing at such a rate that it is impossible to view them without alarm. Does the House realise what British expenditure on armaments amounts to? See how our Army Estimates have grown - seventeen millions in 1894, eighteen in 1897, nineteen in 1899, twenty-four in 1900, and finally in the present year no less than twenty-nine millions eight hundred thousand." However, by 1908 Churchillhad reversed this, in the light of Germany militarism, which required British expenditure on an arms race to maintain credible deterrence. Churchill was a realistic, deterrence-supporting pacifist, not a warmonger. Conventional weapons only failed as a credible deterrent in 1914 because of the instability caused by the need to mobilize them along frontiers, something not needed with long-range nuclear weapons now!
Herman Kahn on p371 states of Churchill's The World Crisis, volume 1: "I know of no better textbook on the subject of war, prewar preparations, and peacetime risks. ... Let me now quote Churchill on the possibility of a surprise attack. He is discussing the tension during the 1911 Agadir crisis. Lloyd George had just made a speech with the idea of forcing the German government to back down. The Germans did not like it ... 'It is too foolish, too fantastic to be thought of ... No one would do such things. Civilisation has climbed above such perils. The interdependence of nations in trade and traffic, the sense of public law, the Hague Convention, Liberal principles, the Labour Party, high finance, Christian charity, common sense have rendered such nightmares impossible. Are you quite sure? It would be a pity to be wrong.' (W. S. Churchill, The World Crisis, v1, Charles Scribner's Sons, NY, 1923, p45)." Kahn then explains the analogy of 1930s fears of gas annihilation to thermonuclear ignorance and propaganda:
"War, unrestricted war, seemed like an unbelievable nightmare and therefore somehow unreal. The very terror of war [annihilation by exaggerated gas or incendiary or high explosive bombing on cities] powerfully reinforced all those who wished to reject military solutions or palliatives in favor of much more attractive schemes for world government or universal disarmament or some major step in that direction.[Italics are Herman Kahn's own.] ... In fact it was not until April 1939, after the second invasion of Czechoslovakia, that the British went all out ... It was by that time far too late." - Herman Kahn, On Thermonuclear War, p377. When Kahn was writing, the USA had massive nuclear superiority in both tactical and strategic weapons. Today, however, the situation is reversed and Kahn's warning is pertinent again: Russia and its allies China, North Korea and Iran have superiority. (We also need to remember the 1939-40 phoney war; it was Churchill not Hitler who initiated city bombing in 1940, deliberately in order to divert enemy bombing from RAF airfields that were needed to retain air superiority and prevent an invasion succeeding. Churchill was only able to do this because Britain had civil defense to mitigate the effects of the retaliation when the RAF were unable to entirely stop enemy attacks. Without civil defense, either Churchill wouldn't have been able to do this, so the airfields might have been put out and an invasion done, or else casualty rates 60 times higher could have resulted in the Blitz (the ratio of WWI bombing casualties per ton of bombs on unprotected civilians, to WWII, when people had shelters).
On page 378 of On Thermonuclear War, Herman Kahn emphasises (italics are Kahn's own): "The whole history of the 1933-1939 period is a clear example of the failure of Type II [deterrence of major provocations like invasion of an ally] and Type III Deterrence [deterrence of minor provocations like rearmament, militarization, etc.]. These failures occurred because neither the British nor the French [don't forget the USA which passed its Neutrality Act in 1935!] had the resolve to use their superior military power or their superior resources to check German aggression until it was too late. ... The longer they put off using their superior power the less credible it became that it would ever be used. Finally their power itself became inferior so that even when its use was seriously threatened, the German government was no longer impressed." Kahn quotes Churchill: "We had been reduced in those five years [of anti-war disarmament and then anti-war appeasement propaganda about gas knockout blow escalations wiping out humanity, 1933-1938, cumulating in the worthless piece of paper signed by Adolf Hitler on 30 September 1938 promising peace for our time] from a position of security so overwhelming and so unchallengable that we never cared to think about it. We have been reduced from a position where the very word 'war' was considered one which would be used only by persons qualifying for a lunatic asylum." - Winston Churchill, Blood, Sweat, and Tears, G. P. Putnam's Sons, NY, 1941, p60 (quoted by Herman Kahn on page 379 of On Thermonuclear War, where Kahn comments: "Hitler and some of his staff were victims of overconfidence. By the time the war started, they felt that they had more than enough of a lead to win. ... the war would doubtless be short [precisely the delusion of Russia when invading Ukraine, in 2022] ..."
Herman Kahn on page 378 of On Thermonuclear War quotes Air Marshall Sir John Slessor's Central Blue Praeger, NY, 1957, which states the reality on page 161: by 1938 Britain was spending £300 million a year on arms, contrasted to well over £1000 million a year then being spent on arms by the Nazis. Thus, the Nazis were far outrunning Britain so that every day of peace that "Chamberlain bought with his peace agreements" actually gave the Nazis a bigger lead; Britain was not "buying time for rearmament to fight" contrary to financially illiterate historians, journalists and other Chamberlain "pacifism" fans to this day, rather, Chamberlain was helping the Nazis prepare better than the UK by delaying war! If the enemy is getting way bigger than you by the day, you don't do yourself any favours by delaying the fight. The fact that this is still "disputed" by left wing historians to back disarmament in the face of Russia today just demonstrates how Comintern's legacy of infiltration of the Western universities and mass media continues to this day.
One final thought from Kahn's On Thermonuclear War is his Figure 8 on page 469, showing the relationship between missile accuracy, warhead yield, and the 50% probable target peak overpressure at the intended ground zero (the intended ground zero never debunked with 100% probability in reality, due to inaccuracies in the missile guidance system, never mind the risk of warhead malfunction/ABM interception): in 1960 American 10 megaton warheads were placed on missiles with good accuracy gyroscopes, CEP = 1 mile, which gave 50% probability of delivering 100 psi peak overpressure to the intended ground zero, destroying typical 1960 era primitive (not shock protected) missile silos. So the USA could take out hard Russian ICBMs at that time. But the corresponding 10 megaton Russian warheads were (supposedly) on less accurate missiles, CEP = 5 miles, which would only deliver about average 4 psi peak overpressure at the intended "ground zero" (because they would on average miss targets by miles), so Russia couldn't in 1960 usefully target American ICBM's in their silos! If they did so, they would fail with high probability, because the hard targets would on average receive only 4 psi, not the 100 psi needed to wreck them. Thus, Russia had to target wood-frame American houses with ICBM's in 1960, the only yank assets that could be wrecked by 4 psi, not missile silos. In effect, missile accuracy forced America and Russia to have different nuclear war strategies: America could use "counterforce" targetting on hard Russian silos, but the less accurate Russian missiles of the same yield class would have to be targetted on "soft countervalue" targets, like residential areas. This asymmetry in USA and Russian targetting was often promoted by "arms control and disarmament" promoters like Hans Bethe as preventing a direct comparison; Bethe wrote articles in journals denying Russian superiority in megatonnage because they had less accurate missiles. But this is fake news, because Russia's a dictatorship, America isn't. Which is more dangerous, Russia wiping out American civilians or America wiping out Russian ICBMs? Duh. One strategy is evil, the other is just war.
Kahn also went into the problem with populist notions of "knockout blow" 1st strikes, versus 2nd strikes in nuclear war. In summary, Russia now has superiority in tactical neutron weapons, protected deep shelters and the secret Metro 2 underground railway to evacuate the dictators from the Kremlin to safe rural bunkers in the event of a nuclear strike on Moscow (as well as many dual-purpose cheap but hard underground car parks/shelters and tube stations/shelters and basement cafes/shelters, with double blast doors fitted for civilians), and it has placed a large number of ICBMs on mobile launchers which can move around (out of the 4 psi damage zone) while USA ICBMs are inflight. So, since America doesn't have such civil defense or mobile ICBM launchers or neutron bombs, it doesn't really have a credible deterrent against Russia, but Russia has a credible deterrent against American nuclear leverage. This was claimed to reduce nclear war risks by demonstrating to Russia that it has nothing to fear from America unless Russia launches a first strike on America, when what survived of American military assets (e.g. some Trident SLBMs) could disarm themselves by setting off a firework display over the Kremlin (while the Russians survive in hard double-blast doored shelters). This limited American "second strike capability" was supposed to be "safe deterrence". However, as we have seen, it hasn't stopped Russia invading Ukraine, using Novichok and Polonium-210 in the UK, etc. In other words, it's "minimal deterrence" that leaves open the key risk Kahn warned about, a repetition of the 1930s fiasco that was designed to minimise the risk of "accidental war" by peace treaties with dictators (who interpreted them as signs of virtual signalling weakness to be laughed at and ignored), but did the opposite, causing WWII. Mathematically, the error is that the Iwo Jima proved Lanchester Equations of war are being disregarded in preference to Morgenstern and von Neumann's "Minimax theorem" of game theory. The Lanchester Equations prove that the probability of victory in war (i.e. the rate of disarmament of the weaker side) is proportional to the square of the ratio of forces (surviving a 1st strike) and you need thus to risk using as much force as you can; the Minimax theorem by contrast says that to win a rule-abided game you should take minimal risks and not "escalate to win". The Minimax theorem is disproved by the US Strategic Bomb Survey WWII pre-nuclear attacks data, as well as the results in Vietnam and other wars of "gradual punishment" to try to coerce the enemy into defeat. The Lanchester equations model the history of victorious combats. All current Western nuclear policy is based on Minimax (the McNamara legacy), not Lanchester!
To recap for clarity in the reader's mind: Kahn's 1960 On Thermonuclear War was written while Eisenhower/Dulles "Massive retaliation" (aka "MAD" = Musual Assured Destruction, aka "Type 1 Deterrence") was in play, although General Maxwell D. Taylor (later Kennedy's limited nuclear war adviser), Henry Kissinger (in his 1957 "Nuclear Weapons and Foreign Policy"), and people like Kahn's childhood friend and RAND Corporation colleague, physicist Samuel Cohen, were already advocating cleaner enhanced neutron weapons to credibly deter the invasions that triggered terrible conventional wars like WWI, WWII, the 1950-53 Korean War, etc. (note that contrary to "arms control and disarmament" liars, the "neutron bomb" is not limited to low kiloton yields, but can be used as a 10 megaton Ripple II 99.9% clean device for the case of wide area fronts of tanks crossing borders, provided a precursor burst of similar yield is detonated 5-25 seconds in advance, in order to reduce air density in the target area behind the shock front of the first burst, and so provide hydrodynamic enhancement of neutrons from the second explosion). Kahn considered a wide range of deterrent postures and kinds of wars in his book, and countermeasures in excruciating detail and cold-bloodedness, which put off many idealists from even bothering to read it carefully, let alone implement all of its recommendations! The key problem Kahn found for today's "minimal deterrence policy" was that arms control plus Russian tactical nuclear weapons and shelters superiority, kills off any hope deterring the kinds of "Type II deterrence" needed to prevent enemies from invading 3rd parties, i.e. the invasion of Ukraine 2022 couldn't be credibly deterred by saying "if you do that, Putin, I'll kill myself by disarming my country by firing all my weapons at you for an imaginary knockout blow" (most of which will be negated by Russian ABM, or negated by Russian shelters, or negated by Russian mobile ICBM's simply starting their engines and driving outside the 4psi blast overturning radius while the pre-programmed ICBM's are in flight from USA to their previous locations in Russia identified on satellite photos prior to pressing the button)!" This simply isn't a credible deterrent to kind of situations which have initiated 100% of the world wars in history! WTF has gone wrong with these people? Comintern propaganda has infected top dogs for decades with "Jaw, jaw, not war, war" appeasement crap (Winston Churchill was the only person in human history in the Cabinet of the country triggering BOTH World Wars, tried to deter BOTH, and FAILED both times, but is somehow remembered in propaganda history as a "great orator" despite failing to sway public opinion pre-WWI and pre-WWII to deter the wars; he may have been the most sensible person on both occasions but the result was still a World War each time!). Maybe it's partly down to luddite opposition to progress (the sin of nuclear technology stagnation caused by decades of bans of tests for improved, more credible nuclear deterrent warhead options), and partly down to nostalgic "last war" style military inertia, of the kind that sent Polish horse mounted (cavalry) divisions into battle with Panzer tanks in 1939. The key problem is that the current "protected second strike capability" ("we will never strike first!") is that the enemy leadership may develop the mentality of Hamas in October 2023. If so, that very limited "minimum deterrence" will fail, and there will be a nuclear war. Also, Russia has threatened to nuke non-nuclear Sweden and non-nuclear Ukraine, just as America nuked non-nuclear Japan in 1945 twice, so the CND fantasy of securing a "nuclear free zone" by unilateral disarmament is just a pipe dream. If we continue as we have done until now, Russia and other enemy states will become an ever more war-minded alliance intent on our nuclear annihilation.

Democrats in 2021 accelerated the pull out from Afghanistan to the extent that people flooded runways and later fell off undercarriages of the escaping aircraft (worse than the organized rooftop queue for the last Helicopters leaving Saigon, in 1975!), to pacify disarmers, peace protestors, liberals etc., like Putin and Hamas, then Putin and Hamas realise they can invade Ukraine (2022) and Israel (2023) with impunity. INNOCENT PEOPLE ARE KILLED WHEN YOU GIVE A GREEN LIGHT TO DICTATORS. We need credible deterrence. Like, NOW, to stop these invasions. Duh. The entire problem is down to the lying left wing Lenin lawyer "virtual signalling" political tactic lampooned years ago by Bob Monkhouse's advice to succeed by "faking sincerity" ("Nukemap" lying crap is an excellent example of how the old 1930s "guaranteed gas knockout blow annihilation within hours of war being declared" propaganda horsecrap is resurrected for mainstream media lying fake "pacicism" today). That deliberate abusive lying propaganda by the herd mentality "autistic groupthink" thugs of left wing bigots backfires, just as with right wing thugs, and costs lives.

It's impossible to tell precisely why this 1930s "gas war will escalate within hours and wipe out everybody" pro-Nazi appeasement escalation-doomsday lying and Vietnam era "don't escalate to win" anti-military lunacy is still prevailing in America and Germany, but nuclear heebie jeebies based on fake "Nukemap" style crap is certainly a big factor, plus the fact that both countries lost major wars with costly financial and psychosis implications (Germany lost WWI and WWII; America lost Vietnam, Iraq, Afghanistan). Someday victory may become fashionable again, probably only after "virtue signalling faked pacifist sincerity" is debunked by Putin.

The basic fact is that nuclear weapons can deter/stop invasions unlike the conventional weapons that cause mass destruction, and nuclear collateral damage is eliminated easily for nuclear weapons by using them on military targets, since for high yields at collateral damage distances all the effects are sufficiently delayed in arrival to allow duck and cover to avoid radiation and blast wind/flying debris injuries (unlike the case for the smaller areas affected by smaller yield conventional weapons, where there is little time on seeing the flash to duck and cover to avoid injury), and as the original 1951 SECRET American Government "Handbook on Capabilities of Atomic Weapons" (limited report AD511880L, forerunner to today's still secret EM-1) stated in Section 10.32:
"PERHAPS THE MOST IMPORTANT ITEM TO BE REMEMBERED WHEN ESTIMATING EFFECTS ON PERSONNEL IS THE AMOUNT OF COVER ACTUALLY INVOLVED. ... IT IS OBVIOUS THAT ONLY A FEW SECONDS WARNING IS NECESSARY UNDER MOST CONDITIONS TO TAKE FAIRLY EFFECTIVE COVER. THE LARGE NUMBER OF CASUALTIES IN JAPAN RESULTED FOR THE MOST PART FROM THE LACK OF WARNING."
As for Hitler's stockpile of 12,000 tons of tabun nerve gas, whose strategic and also tactical use was deterred by proper defences (gas masks for all civilians and soldiers, as well as UK stockpiles of fully trial-tested deliverable biological agent anthrax and mustard gas retaliation capacity), it is possible to deter strategic nuclear escalation to city bombing, even within a world war with a crazy terrorist, if all the people are protected by both defence and deterrence.
This means that they can invade territory with relative impunity, since the West won't deter such provocations by flexible response - the aim of Russia is to push the West into a policy of massive retaliation of direct attacks only, and then use smaller provocations instead - and Russia can then use its tactical nuclear weapons to "defend" its newly invaded territories by declaring them to now be part of Mother Russia and under Moscow's nuclear umbrella. Russia has repeatedly made it clear - for decades - that it expects a direct war with NATO to rapidly escalate into nuclear WWIII and it has prepared civil defense shelters and evacuation tactics to enable it. Herman Kahn's public warnings of this date back to his testimony to the June 1959 Congressional Hearings on the Biological and Environmental Effects of Nuclear War, but for decades were deliberately misrepresented by most media outlets. President Kennedy's book "Why England Slept" makes it crystal clear how exactly the same "pacifist" propaganda tactics in the 1930s (that time it was the "gas bomb knockout blow has no defense so disarm, disarm, disarm" lie) caused war, by using fear to slow credible rearmament in the face of state terrorism. By the time democracies finally decided to issue an ultimatum, Hitler had been converted - by pacifist appeasement - from a cautious tester of Western indecision, into an overconfident aggressor who simply ignored last-minute ultimatums.
Glasstone and Dolan's 1977 Effects of Nuclear Weapons (US Government) is written in a highly ambiguous fashion (negating nearly every definite statement with a deliberately obfuscating contrary statement to leave a smokescreen legacy of needless confusion, obscurity and obfuscation), omits nearly all key nuclear test data and provides instead misleading generalizations of data from generally unspecified weapon designs tested over 60 years ago which apply to freefield measurements on unobstructed radial lines in deserts and oceans. It makes ZERO analysis of the overall shielding of radiation and blast by their energy attenuation in modern steel and concrete cities, and even falsely denies such factors in its discussion of blast in cities and in its naive chart for predicting the percentage of burns types as a function of freefield outdoor thermal radiation, totally ignoring skyline shielding geometry (similar effects apply to freefield nuclear radiation exposure, despite vague attempts to dismiss this by non-quantitative talk about some scattered radiation arriving from all angles). It omits the huge variations in effects due to weapon design e.g. cleaner warhead designs and the tactical neutron bomb. It omits quantitative data on EMP as a function of burst yield, height and weapon design.
It omits most of the detailed data collected from Hiroshima and Nagasaki on the casualty rates as a function of type of building or shelter and blast pressure. It fails to analyse overall standardized casualty rates for different kinds of burst (e.g. shallow underground earth penetrators convert radiation and blast energy into ground shock and cratering against hard targets like silos or enemy bunkers). It omits a detailed analysis of blast precursor effects. It omits a detailed analysis of fallout beta and gamma spectra, fractionation, specific activity (determining the visibility of the fallout as a function of radiation hazard, and the mass of material to be removed for effective decontamination), and data which does exist on the effect of crater soil size distribution upon the fused fallout particle size distribution (e.g. tests like Small Boy in 1962 on the very fine particles at Frenchman Flats gave mean fallout particle sizes far bigger than the pre-shot soil, proving that - as for Trinitite - melted small soil particles fuse together in the fireball to produce larger fallout particles, so the pre-shot soil size distribution is irrelevant for fallout analysis).
By generally (with few exceptions) lumping "effects" of all types of bursts together into chapters dedicated to specific effects, it falsely gives the impression that all types of nuclear explosions produce similar effects with merely "quantitative differences". This is untrue because air bursts eliminate fallout casualties entirely, while slight burial (e.g. earth penetrating warheads) eliminates thermal (including fires and dust "climatic nuclear winter" BS), the initial radiation and severe blast effects, while massively increasing ground shock, and the same applies to shallow underwater bursts. So a more objective treatment to credibly deter all aggression MUST emphasise the totally different collateral damage effects, by dedicating chapters to different kinds of burst (high altitude/space bursts, free air bursts, surface bursts, underground bursts, underwater bursts), and would include bomb design implications on these effects in detail. A great deal of previously secret and limited distributed nuclear effects data has been declassified since 1977, and new research has been done. Our objectives in this review are: (a) to ensure that an objective independent analysis of the relevant nuclear weapons effects facts is placed on the record in case the currently, increasingly vicious Cold War 2.0 escalates into some kind of limited "nuclear demonstration" by aggressors to try to end a conventional war by using coercive threats, (b) to ensure the lessons of tactical nuclear weapon design for deterring large scale provocations (like the invasions of Belgium in 1914 and Poland in 1939 which triggered world wars) are re-learned in contrast to Dulles "massive retaliation" (incredible deterrent) nonsense, and finally (c) to provide some push to Western governments to "get real" with our civil defense, to try to make credible our ageing "strategic nuclear deterrent". We have also provided a detailed analysis of recently declassified Russian nuclear warhead design data, shelter data, effects data, tactical nuclear weapons employment manuals, and some suggestions for improving Western thermonuclear warheads to improve deterrence.
‘The evidence from Hiroshima indicates that blast survivors, both injured and uninjured, in buildings later consumed by fire [caused by the blast overturning charcoal braziers used for breakfast in inflammable wooden houses filled with easily ignitable bamboo furnishings and paper screens] were generally able to move to safe areas following the explosion. Of 130 major buildings studied by the U.S. Strategic Bombing Survey ... 107 were ultimately burned out ... Of those suffering fire, about 20 percent were burning after the first half hour. The remainder were consumed by fire spread, some as late as 15 hours after the blast. This situation is not unlike the one our computer-based fire spread model described for Detroit.’

The Effects of the Atomic Bomb on Hiroshima, Japan, US Strategic Bombing Survey, Pacific Theatre, report 92, volume 2 (May 1947, secret):
Volume one, page 14:
“... the city lacked buildings with fire-protective features such as automatic fire doors and automatic sprinkler systems”, and pages 26-28 state the heat flash in Hiroshima was only:
“... capable of starting primary fires in exposed, easily combustible materials such as dark cloth, thin paper, or dry rotted wood exposed to direct radiation at distances usually within 4,000 feet of the point of detonation (AZ).”
Volume two examines the firestorm and the ignition of clothing by the thermal radiation flash in Hiroshima:
Page 24:
“Scores of persons throughout all sections of the city were questioned concerning the ignition of clothing by the flash from the bomb. ... Ten school boys were located during the study who had been in school yards about 6,200 feet east and 7,000 feet west, respectively, from AZ [air zero]. These boys had flash burns on the portions of their faces which had been directly exposed to rays of the bomb. The boys’ stories were consistent to the effect that their clothing, apparently of cotton materials, ‘smoked,’ but did not burst into flame. ... a boy’s coat ... started to smoulder from heat rays at 3,800 feet from AZ.” [Contrast this to the obfuscation and vagueness in Glasstone, The Effects of Nuclear Weapons!]
Page 88:
“Ignition of the City. ... Only directly exposed surfaces were flash burned. Measured from GZ, flash burns on wood poles were observed at 13,000 feet, granite was roughened or spalled by heat at 1,300 feet, and vitreous tiles on roofs were blistered at 4,000 feet. ... six persons who had been in reinforced-concrete buildings within 3,200 feet of air zero stated that black cotton blackout curtains were ignited by radiant heat ... dark clothing was scorched and, in some cases, reported to have burst into flame from flash heat [although as the 1946 unclassified USSBS report admits, most immediately beat the flames out with their hands without sustaining injury, because the clothing was not drenched in gasoline, unlike peacetime gasoline tanker road accident victims]
“... but a large proportion of over 1,000 persons questioned was in agreement that a great majority of the original fires was started by debris falling on kitchen charcoal fires, by industrial process fires, or by electric short circuits. Hundreds of fires were reported to have started in the centre of the city within 10 minutes after the explosion. Of the total number of buildings investigated [135 buildings are listed] 107 caught fire, and in 69 instances, the probable cause of initial ignition of the buildings or their contents was as follows: (1) 8 by direct radiated heat from the bomb (primary fire), (2) 8 by secondary sources, and (3) 53 by fire spread from exposed [wooden] buildings.”
There is now a relatively long introduction at the top of this blog, due to the present nuclear threat caused by disarmament and arms control propaganda, and the dire need to get the facts out past pro-Russian media influencers or loony mass media which has never cared about nuclear and radiation effects facts, so please scroll down to see blog posts. The text below in blue is hyperlinked (direct to reference source materials, rather than numbered and linked to reference at the end of the page) so you can right-click on it and open in a new tab to see the source. This page is not about opinions, it provides censored out facts that debunk propaganda, but for those who require background "authority" nonsense on censored physics facts, see stuff here or here. Regarding calling war-mongering, world war causing, terrorism-regime-supporting UK disarmers of the 20th century "thugs" instead of "kind language": I was put through the Christianity grinder as a kid so will quote Jesus (whom I'm instructed to follow), Matthew 23:33: "Ye serpents, ye generation of vipers, how can ye escape the damnation of Hell?" The fake "pacifist" thugs will respond with some kindly suggestion that this is "paranoid" and that "Jesus was rightfully no-platformed for his inappropriate language"! Yeah, you guys would say that, wouldn't ya. Genuine pacifism requires credible deterrence! Decent people seem to be very confused about the facts of this. Jesus did not say "disarm to invite your annihilation by terrorists". You can't "forgive and forget" when the enemy is still on the warpath. They have to be stopped, either by deterrence, force, defense, or a combination of all these.
ABOVE: The June 1957 edition of Glasstone's Effects of Nuclear Weapons was the first to include the effects of blast duration (which increases with the cube-root of weapon yield) on blast damage from nuclear weapons. This is very important for wind drag loading to drag-sensitive targets, but has less effect for diffraction-sensitive targets which respond to peak pressures, especially where the blast pressure rapidly equalizes around the structure (e.g. utility poles or buildings with large expanses of glass which shatters, allowing rapid pressure equalization). For example, Glasstone 1957, Fig. 6.41b (p253, using Fig. 3.94a on p109 to convert scaled distances to overpressures from a surface burst on open deserted terrain) shows that for yields of 1 kt, 20 kt (approximately the 16 kt Hiroshima and 21 kt Nagasaki yields), and 1 megaton, peak overpressures of 55, 23 and 15 psi, respectively, are required for collapse (severe damage) to modern multistory reinforced concrete buildings with light walls (Fig. 6.41a shows that about 5 psi will demolish a wood frame house - no longer in modern city centres - regardless of yield). Notice that this means that modern cities are extremely resistant to blast from ~1 kt neutron bombs, requiring more than twice the peak overpressure for collapse than was needed in Hiroshima and Nagasaki. Also notice that very large amounts of energy are absorbed from the blast in causing severe damage to modern reinforced concrete city buildings, causing rapid attenuation of free-field pressure so that ocean and desert test validated cube-root damage scaling laws break down for high yield bursts in modern cities (see latest blog post here for examples of calculations of this energy absorption in both oscillating a building in the elastic deflection engineering graph zone, and the much larger energy absorption in causing plastic zone distortion to reinforced concrete - basically the former typically absorbs about 1% of blast energy, whereas the latter takes up something like 10 times more energy, or 10%, a factor entirely dismissed by Glasstone and Dolan but analyzed by Penney). Above a megaton or so, the increasing blast duration has less and less effect on the peak overpressure required for severe damage, because for destruction a threshold blast loading exists, regardless of the blast duration. (A 1 mile/hour wind will not blow a wall down, regardless of how long it lasts. In other words, large impulses cease to be damage criteria if the blast pressure drops below a threshold needed for damage.) Glasstone 1957 Fig 6.41c on p255 shows that automobiles suffer severe damage 36 psi peak overpressure for 1 kt, 18 psi for 20 kt, and 12 psi for 1 megaton. These pressures for destruction of automobiles are similar to the severe damage data given for multistorey steel frame office buildings with light walls. The key point here is that low-yield (around 1 kt) tactical nuclear weapons produce far less collateral damage to civilian infrastructure than high yield bursts, and even the effects of the latter are exaggerated severely for modern cities when using wooden house data in unobstructed terrain at ocean or desert terrain nuclear tests. Collateral damage is eliminated by exploiting the fact that higher pressures are needed for air blast damage at lower yields, and using earth penetrator warheads or air bursts to constrain air blast pressures to civilian infrastructure, ensuring that they are not collapsed (causing casualties in modern steel or concrete buildings).
Note that the later (1962/4 and 1977) editions of The Effects of Nuclear Weapons replace the correct (curved line conversion) blast duration nomographs in the 1957 edition with simplistic Wn yield scaling (where n = 0.4 for drag sensitive targets), which is a simplification which fails to correctly model the fact that blast duration effects on overpressures are eliminated at very high yields because a minimum threshold blast pressure is needed to cause damage.
J. R. Oppenheimer (opposing Teller), February 1951: "It is clear that they can be used only as adjuncts in a military campaign which has some other components, and whose purpose is a military victory. They are not primarily weapons of totality or terror, but weapons used to give combat forces help they would otherwise lack. They are an integral part of military operations. Only when the atomic bomb is recognized as useful insofar as it is an integral part of military operations, will it really be of much help in the fighting of a war, rather than in warning all mankind to avert it." (Quotation: Samuel Cohen, Shame, 2nd ed., 2005, page 99.)
‘The Hungarian revolution of October and November 1956 demonstrated the difficulty faced even by a vastly superior army in attempting to dominate hostile territory. The [Soviet Union] Red Army finally had to concentrate twenty-two divisions in order to crush a practically unarmed population. ... With proper tactics, nuclear war need not be as destructive as it appears when we think of [World War II nuclear city bombing like Hiroshima]. The high casualty estimates for nuclear war are based on the assumption that the most suitable targets are those of conventional warfare: cities to interdict communications ... With cities no longer serving as key elements in the communications system of the military forces, the risks of initiating city bombing may outweigh the gains which can be achieved. ...
‘The elimination of area targets will place an upper limit on the size of weapons it will be profitable to use. Since fall-out becomes a serious problem [i.e. fallout contaminated areas which are so large that thousands of people would need to evacuate or shelter indoors for up to two weeks] only in the range of explosive power of 500 kilotons and above, it could be proposed that no weapon larger than 500 kilotons will be employed unless the enemy uses it first. Concurrently, the United States could take advantage of a new development which significantly reduces fall-out by eliminating the last stage of the fission-fusion-fission process.’
- Dr Henry Kissinger, Nuclear Weapons and Foreign Policy, Harper, New York, 1957, pp. 180-3, 228-9.
Note that sometimes the "nuclear taboo" issue is raised against this analysis by Kissenger: if anti-nuclear lying propaganda on weapons effects makes it apparently taboo in the Western pro-Russian disarmament lobbies to escalate from conventional to tactical nuclear weapons to end war as on 6 and 9 August 1945, then this "nuclear taboo" can be relied upon to guarantee peace for our time. However, this was not only disproved by Hiroshima and Nagasaki, but by the Russian tactical nuclear weapons reliance today, the Russian civil defense shelter system detailed on this blog which showed they believed a nuclear war survivable based on the results of their own nuclear tests, and the use of Russian nuclear weapons years after Kissinger's analysis was published and criticised, for example their 50 megaton test in 1961 and their supply of IRBM's capable of reaching East Coast mainland USA targets to the fanatical Cuban dictatorship in 1962. So much for the "nuclear taboo" as being any more reliable than Chamberlain's "peace for our time" document, co-signed by Hitler on 30 September 1938! We furthermore saw how Russia respected President Obama's "red line" for the "chemical weapons taboo": Russia didn't give a toss about Western disarmament thugs prattle about what they think is a "taboo", Russia used chlorine and sarin in Syria to keep Assad the dictator and they used Novichok to attack and kill in the UK in 2018, with only diplomatic expulsions in response. "Taboos" are no more valid to restrain madmen than peace treaties, disarmament agreements, Western CND books attacking civil defense or claiming that nuclear war is the new 1930s gas war bogyman, or "secret" stamps on scientific facts. In a word, they're crazy superstitions.)
All of this data should have been published to inform public debate on the basis for credible nuclear deterrence of war and civil defense, PREVENTING MILLIONS OF DEATHS SINCE WWII, instead of DELIBERATELY allowing enemy anti-nuclear and anti-civil defence lying propaganda from Russian supporting evil fascists to fill the public data vacuum, killing millions by allowing civil defence and war deterrence to be dismissed by ignorant "politicians" in the West, so that wars triggered by invasions with mass civilian casualties continue today for no purpose other than to promote terrorist agendas of hate and evil arrogance and lying for war, falsely labelled "arms control and disarmament for peace":
"Controlling escalation is really an exercise in deterrence, which means providing effective disincentives to unwanted enemy actions. Contrary to widely endorsed opinion, the use or threat of nuclear weapons in tactical operations seems at least as likely to check [as Hiroshima and Nagasaki] as to promote the expansion of hostilities [providing we're not in a situation of Russian biased arms control and disarmament whereby we've no tactical weapons while the enemy has over 2000 neutron bombs thanks to "peace" propaganda from Russian thugs]." - Bernard Brodie, pvi of Escalation and the nuclear option, RAND Corp memo RM-5444-PR, June 1965.
ABOVE: Why didn't Britain declare war on Russia when it jointly invaded Poland with the Nazis, or even later when Russia invaded Finland single-handed? Answer: Comintern had stuffed the British mass media, British universities, and even the Labour Party with Russian stooges! Barrister Denis Pritt, Labour MP, simply blamed the British government for not cosying up to Communist dictatorial Russia (in the same way Chamberlain had cosied up to Adolf Hitler's Nazis)! Pritt in 1936 went to watch the "Trial of the Sixteen" in Moscow, a show trial purge of Stalin's criticis that made a mockery of the law, but be defended Stalinism in his tract, "The Zinoviev Trial". He was only finally kicked out of the Labour Party after he defended Russia's invasion of Finland in popular Penguin Book Specials. But he wasn't alone. The communists of the British media used the same tactics as the Nazis to undermine or destroy critics, so they managed to churn out one-sided propaganda nearly as bad as the media saturation with anti-nuclear, anti-CO2 crap today.
Russian project 49 dual-primary thermonuclear weaponeer Dr Yuri Trutnev has an officially "proatom.ru"-published technical history of the design of the Russian nuclear weapons (which differ from UK-USA designs fundamentally) here (extracted from Russian "Atomic Strategy" No. 18, August 2005): "the problem of ensuring spherically symmetric compression of the secondary module was radically solved, since the time of “symmetrization” of the energy around the secondary module was much less than the time of compression of this module. ... The first two-stage thermonuclear charge, designated RDS-37, was developed in 1955 and successfully tested on November 22, 1955. The energy release of the charge in the experiment was 1.6 Mt, and since for safety reasons at the Semipalatinsk test site the charge was tested at partial power, the predicted full-scale energy release of the charge was ~ 3 Mt. The energy release amplification factor in RDS-37 was about two orders of magnitude, the charge did not use tritium, the thermonuclear fuel was lithium deuteride, and the main fissile material was U-238. ... Particular attention should be paid to the works of 1958. This year, a new type of thermonuclear charge, “product 49,” was tested [the double-primary H-bomb], which was the next step in the formation of a standard for thermonuclear charges (its development was completed in 1957, but testing on the SIP did not take place). The ideologists of this project and the developers of the physical charge circuit were Yu. N. Babaev and I. The peculiarity of the new charge was that, using the basic principles of the RDS-37, it was possible to: • significantly reduce overall parameters due to a new bold solution to the problem of transfer of X-ray radiation, which determines implosion; • simplify the layered structure of the secondary module, which turned out to be an extremely important practical decision. According to the conditions of adaptation to specific carriers, “product 49” was developed in a smaller overall weight category compared to the RDS-37 charge, but its specific volumetric energy release turned out to be 2.4 times greater.
"The physical design of the charge turned out to be extremely successful; the charge was transferred to service and subsequently underwent modernization associated with the replacement of primary energy sources. In 1958, together with Yu. N. Babaev, we managed to develop 4 thermonuclear charges, which were tested on the field in 7 full-scale tests, and all of them were successful. This work was practically implemented within 8 months of 1958. All of these charges used a new circuit, first introduced in Product 49. Their energy release ranged from 0.3 to 2.8 Mt. In addition, in 1958, under my leadership M. V. Fedulov also developed the lightest thermonuclear charge at that time according to the “product 49” design, which was also successfully tested. Work on the miniaturization of thermonuclear weapons was new at that time, and it was met with a certain misunderstanding and resistance. ... One of the well-known pages in the history of work on thermonuclear weapons of the USSR is the creation of a superbomb - the most powerful thermonuclear charge. I will dwell on some points of this development. ... Among the features of this charge, it should be noted that the large volume of the charge (due to its high energy release) required significant amounts of X-ray energy to carry out implosion. The developed nuclear charges did not satisfy this condition, and therefore, a previously developed two-stage thermonuclear charge with a relatively low energy release was used as the primary source of the “super-powerful charge”. This charge was developed by me and Yu. N. Babaev. ... In the next project (a return to the untested 1958 system) that I supervised, every effort was made to ensure near-perfect implosion symmetry. This brilliant work led to success, and in 1962, the problem of implementing thermonuclear ignition was solved in a special device. In other full-scale tests that followed, this success was consolidated, and as a result, thermonuclear ignition provided the calculated combustion of the secondary module with an energy release of 1 Mt. My co-authors in this development were V.B. Adamsky, Yu.N. Babaev, V.G. Zagrafov and V.N. Mokhov. ... This principle has found a variety of applications in the creation of fundamentally new types of thermonuclear charges, from special devices for the use of nuclear explosions for peaceful purposes to significant military applications." (Note there is a 2017 filmed interview of Trutnev - in Russian - linked here.)
"... it is an important defect of 'arms control' agreements that the punishment or correction of even outright violation is not done automatically ... [in 1934 Ramsay] MacDonald and his supporters urged one of the least aggressive nations in Europe to disarm itself to a level equal with their potential attackers ... Probably as much as any other single group I think that these men of good will can be charged with causing World War II. [Italics are Kahn's own.] ... In March 1934, Stanley Baldwin, in answer to a statement by Winston Churchill to the effect that Germany was rearming and growing stronger than Great Britain, made his famous statement: 'If all our efforts at agreement fail [why 'all' and how do you define 'failure' until after the enemy secretly breaks the agreement and enemy starts a war, when it is too late?] ... in air strength and air power this country shall no longer be inferior to any country within striking distance of its shores'. In spite of this pledge, by 1935 the Germans had achieved parity or even air superiority and their rate of expansion was much larger than that of the British; thus the disparity grew with the years. ... On March 16, 1935, Hitler decreed conscription ... In April, the League [of Nations, the old version of the UN] ... unanimously voted that treaties should not be broken by unilateral action. ... At no time did Hitler threaten to initiate war against France and England. He simply threatened to 'retaliate' if they attacked him. ... The technique he used is such an obvious prototype for a future aggressor armed with H-bombs that it is of extreme value to all who are concerned with the problem of maintaining a peaceful and secure world to go over the story in some detail." - Kahn, On Thermonuclear War, pp. 390-392, 403. (Kahn then gives a long discussion of the "you have the choice"-way Hitler blackmailed President Hacha into signing over his country to the Nazis in March 1939, despite the worthless Munich agreement of 1938, using first-hand testimony from Hitler's translator at the 14 March 1939 Hitler-Hacha meeting, Paul Schmidt: "There were, said Hitler, 'two possibilities. The first was that the invasion of the German troops might develop into a battle. The resistance would then be broken down by force of arms with all available means. The other was that the entry of the German troops should take place in a peaceable manner ...'." Now the issue is this: Hitler used "peace" as an option to get what he wanted without violence. But populist propaganda claims Hitler was "violent". Nope: Hitler preferred to "peacefully" invade, "peacefully" gas opponents in gas chambers with musicians playing classical music at the deportation camp railway stations to prevent violence starting, etc. Reagan made the point in his March 1983 "evil empire" speech that the most evil thugs of all that instigate genocide hide behind the cloak of spurious pacifism!)
https://hbr.org/1995/05/why-the-news-is-not-the-truth/ (Peter Vanderwicken in the Harvard Business Review Magazine, May-June 1995): "The news media and the government are entwined in a vicious circle of mutual manipulation, mythmaking, and self-interest. Journalists need crises to dramatize news, and government officials need to appear to be responding to crises. Too often, the crises are not really crises but joint fabrications. The two institutions have become so ensnared in a symbiotic web of lies that the news media are unable to tell the public what is true and the government is unable to govern effectively. That is the thesis advanced by Paul H. Weaver, a former political scientist (at Harvard University), journalist (at Fortune magazine), and corporate communications executive (at Ford Motor Company), in his provocative analysis entitled News and the Culture of Lying: How Journalism Really Works ... The news media and the government have created a charade that serves their own interests but misleads the public. Officials oblige the media’s need for drama by fabricating crises and stage-managing their responses, thereby enhancing their own prestige and power. Journalists dutifully report those fabrications. Both parties know the articles are self-aggrandizing manipulations and fail to inform the public about the more complex but boring issues of government policy and activity. What has emerged, Weaver argues, is a culture of lying. ... The architect of the transformation was not a political leader or a constitutional convention but Joseph Pulitzer, who in 1883 bought the sleepy New York World and in 20 years made it the country’s largest newspaper. Pulitzer accomplished that by bringing drama to news—by turning news articles into stories ... His journalism took events out of their dry, institutional contexts and made them emotional rather than rational, immediate rather than considered, and sensational rather than informative. The press became a stage on which the actions of government were a series of dramas. ... The press swarmed on the story, which had all the necessary dramatic elements: a foot-dragging bureaucracy, a study finding that the country’s favorite fruit was poisoning its children, and movie stars opposing the pesticide. Sales of apples collapsed. Within months, Alar’s manufacturer withdrew it from the market, although both the EPA and the Food and Drug Administration stated that they believed Alar levels on apples were safe. The outcry simply overwhelmed scientific evidence. That happens all too often, Cynthia Crossen argues in her book Tainted Truth: The Manipulation of Fact in America. ... Crossen writes, “more and more of the information we use to buy, elect, advise, acquit and heal has been created not to expand our knowledge but to sell a product or advance a cause.” “Most members of the media are ill-equipped to judge a technical study,” Crossen correctly points out. “Even if the science hasn’t been explained or published in a U.S. journal, the media may jump on a study if it promises entertainment for readers or viewers. And if the media jump, that is good enough for many Americans.” ... A press driven by drama and crises creates a government driven by response to crises. Such an “emergency government can’t govern,” Weaver concludes. “Not only does public support for emergency policies evaporate the minute they’re in place and the crisis passes, but officials acting in the emergency mode can’t make meaningful public policies. According to the classic textbook definition, government is the authoritative allocation of values, and emergency government doesn’t authoritatively allocate values.” (Note that Richard Rhodes' Pulitzer prize winning books such as The making of the atomic bomb which uncritically quote Hiroshima firestorm lies and survivors nonsense about people running around without feet, play to this kind of emotional fantasy mythology of nuclear deterrence obfuscation so loved by the mass media.)
“... Freedom is the right to question, and change the established way of doing things. It is the continuing revolution ... It is the understanding that allows us to recognize shortcomings and seek solutions. It is the right to put forth an idea ....” – Ronald Reagan, Moscow State University, May 31, 1988 (quoted at our physics site, www.quantumfieldtheory.org).

ABOVE: "missile gap" propaganda debunked by secret 1970s data; Kennedy relied on US nuclear superiority. Using a flawed analysis of nuclear weapons effects on Hiroshima - based on lying unclassified propaganda reports and ignorant dismissals of civil defense shelters in Russia (again based on Hiroshima propaganda by groves in 1945) - America allowed Russian nuclear superiority in the 1970s. Increasingly, the nuclear deterrent was used by Russia to stop the West from "interfering" with its aggressive invasions and wars, precisely Hitler's 1930s strategy with gas bombing knockout-blow threats used to engineer appeasement. BELOW: H-bomb effects and design secrecy led to tragic mass media delusions, such as the 18 February 1950 Picture Post claim that the H-bomb can devastate Australia (inspiring the Shute novel and movie "On the Beach" and also other radiation scams like "Dr Strangelove" to be used by Russia to stir up anti Western disarmament movement to help Russia win WWIII). Dad was a Civil Defense Corps Instructor in the UK when this was done (the civil defense effectiveness and weapon effects facts on shelters at UK and USA nuclear tests were kept secret and not used to debunk lying political appeasement propaganda tricks in the mass media by sensationalist "journalists" and Russian "sputniks"):
Message to mass-media journalists: please don't indulge in lying "no defence" propaganda as was done by most of the media in previous pre-war crises!
Again, to recap: the biggest threat is nuclear coercion as occurred when Russia broke a ceasefire and resumed nuclear testing in 1961, and built the Berlin Wall, then in 1962 put nuclear weapons into Cuba's fanatical dictatorship. This is not the mainstream media portrayal of the "nuclear threat" (immediate knockout blow, total disarmament in a few seconds by exploding everything in the stockpile, which is loved by TV, newspapers, magazines, and films and which - like the gas bomb knockout blow hype of the 1930s - makes war appear "unthinkable" to support appeasement, disarmament and arms control delusions which are bits of paper that simply can't stop the real threats from dictatorships). At some point there may be a serious deliberate escalation to end the war, and we need to be prepared and ready to step up deterrence against this, or to respond rationally in some other way. The supply of F16s by NATO members to Ukraine to bomb targets in Russia will allow Putin the excuse he feels he needs to escalate nuclear threats further, so we must prepare. This is not "defeatism", but preparing for freedom to prevail, to win the war, to deter escalation, and to survive.
ABOVE: Example of a possible Russian 1985 1st Cold War SLBM first strike plan. The initial use of Russian SLBM launched nuclear missiles from off-coast against command and control centres (i.e. nuclear explosions to destroy warning satellite communications centres by radiation on satellites as well as EMP against ground targets, rather than missiles launched from Russia against cities, as assumed by 100% of the Cold War left-wing propaganda) is allegedly a Russian "fog of war" strategy. Such a "demonstration strike" is aimed essentially at causing confusion about what is going on, who is responsible - it is not quick or easy to finger-print high altitude bursts fired by SLBM's from submerged submarines to a particular country because you don't get fallout samples to identify isotopic plutonium composition. Russia could immediately deny the attack (implying, probably to the applause of the left-wingers that this was some kind of American training exercise or computer based nuclear weapons "accident", similar to those depicted in numerous anti-nuclear Cold War propaganda films). Thinly-veiled ultimatums and blackmail follow. America would not lose its population or even key cities in such a first strike (contrary to left-wing propaganda fiction), as with Pearl Harbor in 1941; it would lose its complacency and its sense of security through isolationism, and would either be forced into a humiliating defeat or a major war.
Before 1941, many warned of the risks but were dismissed on the basis that Japan was a smaller country with a smaller economy than the USA and war was therefore absurd (similar to the way Churchill's warnings about European dictators were dismissed by "arms-race opposing pacifists" not only in the 1930s, but even before WWI; for example Professor Cyril Joad documents in the 1939 book "Why War?" his first hand witnessing of Winston Churchill's pre-WWI warning and call for an arms-race to deter that war, as dismissed by the sneering Norman Angell who claimed an arms race would cause a war rather than avert one by bankrupting the terrorist state). It is vital to note that there is an immense pressure against warnings of Russian nuclear superiority even today, most of it contradictory. E.g. the left wing and Russian-biased "experts" whose voices are the only ones reported in the Western media (traditionally led by "Scientific American" and "Bulletin of the Atomic Scientists"), simultaneously claim Russia imposes such a terrible SLBM and ICBM nuclear threat that we must desperately disarm now, while also claiming that Russian tactical nuclear weapons probably won't work so aren't a threat that needs to be credibly deterred! This only makes sense as Russian siding propaganda. In similar vein, Teller-critic Hans Bethe also used to falsely "dismiss" Russian nuclear superiority by claiming (with quotes from Brezhnev about the peaceful intentions of Russia) that Russian delivery systems are "less accurate" than Western missiles (as if accuracy has anything to do with high altitude EMP strikes, where the effects cover huge areas, or large city targets. Such claims would then by repeatedly endlessly in the Western media by Russian biased "journalists" or agents of influence, and any attempt to point out the propaganda (i.e. he real world asymmetry: Russia uses cheap countervalue targetting on folk that don't have civil defense, whereas we need costly, accurate counterforce targetting because Russia has civil defense shelters that we don't have) became a "Reds under beds" argument, implying that the truth is dangerous to "peaceful coexistence"!
“Free peoples ... will make war only when driven to it by tyrants. ... there have been no wars between well-established democracies. ... the probability ... that the absence of wars between well-established democracies is a mere accident [is] less than one chance in a thousand. ... there have been more than enough to provide robust statistics ... When toleration of dissent has persisted for three years, but not until then, we can call a new republic ‘well established.’ ... Time and again we observe authoritarian leaders ... using coercion rather than seeking mutual accommodation ... Republican behaviour ... in quite a few cases ... created an ‘appeasement trap.’ The republic tried to accommodate a tyrant as if he were a fellow republican; the tyrant concluded that he could safely make an aggressive response; eventually the republic replied furiously with war. The frequency of such errors on both sides is evidence that negotiating styles are not based strictly on sound reasoning.” - Spencer Weart, Never at War: Why Democracies Will Not Fight One Another (Yale University Press)
The Top Secret American intelligency report NIE 11-3/8-74 "Soviet Forces for Intercontinental Conflict" warned on page 6: "the USSR has largely eliminated previous US quantitative advantages in strategic offensive forces." page 9 of the report estimated that the Russian's ICBM and SLBM launchers exceed the USAs 1,700 during 1970, while Russia's on-line missile throw weight had exceeded the USA's one thousand tons back in 1967! Because the USA had more long-range bombers which can carry high-yield bombs than Russia (bombers are more vulnerable to air defences so were not Russia's priority), it took a little longer for Russia to exceed the USA in equivalent megatons, but the 1976 Top Secret American report NIE 11-3/8-76 at page 17 shows that in 1974 Russia exceeded the 4,000 equivalent-megatons payload of USA missiles and aircraft (with less vulnerability for Russia, since most of Russia's nuclear weapons were on missiles not in SAM-vulnerable aircraft), amd by 1976 Russia could deliver 7,000 tons of payload by missiles compared to just 4,000 tons on the USA side. These reports were kept secret for decades to protect the intelligence sources, but they were based on hard evidence. For example, in August 1974 the Hughes Aircraft Company used a specially designed ship (Glomar Explorer, 618 feet long, developed under a secret CIA contract) to recover nuclear weapons and their secret manuals from a Russian submarine which sank in 16,000 feet of water, while in 1976 America was able to take apart the electronics systems in a state-of-the-art Russian MIG-25 fighter which was flown to Japan by defector Viktor Belenko, discovering that it used exclusively EMP-hard miniature vacuum tubes with no EMP-vulnerable solid state components.
There are four ways of dealing with aggressors: conquest (fight them), intimidation (deter them), fortification (shelter against their attacks; historically used as castles, walled cities and even walled countries in the case of China's 1,100 mile long Great Wall and Hadrian's Wall, while the USA has used the Pacific and Atlantic as successful moats against invasion, at least since Britain invaded Washington D.C. back in 1812), and friendship (which if you are too weak to fight, means appeasing them, as Chamberlain shook hands with Hitler for worthless peace promises). These are not mutually exclusive: you can use combinations. If you are very strong in offensive capability and also have walls to protect you while your back is turned, you can - as Teddy Roosevelt put it (quoting a West African proverb): "Speak softly and carry a big stick." But if you are weak, speaking softly makes you a target, vulnerable to coercion. This is why we don't send troops directly to Ukraine. When elected in 1960, Kennedy introduced "flexible response" to replace Dulles' "massive retaliation", by addressing the need to deter large provocations without being forced to decide between the unwelcome options of "surrender or all-out nuclear war" (Herman Kahn called this flexible response "Type 2 Deterrence"). This was eroded by both Russian civil defense and their emerging superiority in the 1970s: a real missiles and bombers gap emerged in 1972 when the USSR reached and then exceeded the 2,200 of the USA, while in 1974 the USSR achieve parity at 3,500 equivalent megatons (then exceeded the USA), and finally today Russia has over 2,000 dedicated clean enhanced neutron tactical nuclear weapons and we have none (except low-neutron output B61 multipurpose bombs). (Robert Jastrow's 1985 book How to make nuclear Weapons obsolete was the first to have graphs showing the downward trend in nuclear weapon yields created by the development of miniaturized MIRV warheads for missiles and tactical weapons: he shows that the average size of US warheads fell from 3 megatons in 1960 to 200 kilotons in 1980, and from a total of 12,000 megatons in 1960 to 3,000 megatons in 1980.)
The term "equivalent megatons" roughly takes account of the fact that the areas of cratering, blast and radiation damage scale not linearly with energy but as something like the 2/3 power of energy release; but note that close-in cratering scales as a significantly smaller power of energy than 2/3, while blast wind drag displacement of jeeps in open desert scales as a larger power of energy than 2/3. Comparisons of equivalent megatonnage shows, for example, that WWII's 2 megatons of TNT in the form of about 20,000,000 separate conventional 100 kg (0.1 ton) explosives is equivalent to 20,000,000 x (10-7)2/3 = 431 separate 1 megaton explosions! The point is, nuclear weapons are not of a different order of magnitude to conventional warfare, because: (1) devastated areas don't scale in proportion to energy release, (2) the number of nuclear weapons is very much smaller than the number of conventional bombs dropped in conventional war, (3) because of radiation effects like neutrons and intense EMP, it is possible to eliminate physical destruction by nuclear weapons by a combination of weapon design (e.g. very clean bombs like 99.9% fusion Dominic-Housatonic, or 95% fusion Redwing-Navajo) and burst altitude or depth for hard targets, and create a weapon that deters invasions credibly (without lying local fallout radiation hazards), something none of the biased "pacifist disarmament" lobbies (which attract Russian support) tell you, and (4) people at collateral damage distances have time to take cover from radiation and flying glass, blast winds, etc from nuclear explosions (which they don't in Ukraine and Gaza where similar blast pressures arrive more rapidly from smaller conventional explosions). There's a big problem with propaganda here.
(These calculations, showing that even if strategic bombing had worked in WWII - and the US Strategic Bombing Survey concluded it failed, thus the early Cold War effort to develop and test tactical nuclear weapons and train for tactical nuclear war in Nevada field exercises - you need over 400 megaton weapons to give the equivalent of WWII city destruction in Europe and Japan, are often inverted by anti-nuclear bigots to try to obfuscate the truth. What we're driving at is that nuclear weapons give you the ability to DETER the invasions that set off such wars, regardless of whether they escalate from poison gas - as feared in the 20s and 30s thus appeasement and WWII - or nuclear. Escalation was debunked in WWII where the only use of poison gases were in "peaceful" gas chambers, not dropped on cities. Rather than justifying appeasement, the "peaceful" massacre of millions in gas chambers justified war. But evil could and should have been deterred. The "anti-war" propagandarists like Lord Noel-Baker and pals who guaranteed immediate gas knockout blows in the 30s if we didn't appease evil dictators were never held to account and properly debunked by historians after the war, so they converted from gas liars to nuclear liars in the Cold War and went on winning "peace" prices for their lies, which multiplied up over the years, to keep getting news media headlines and Nobel Peace Prizes for starting and sustaining unnecessary wars and massacres by dictators. There's also a military side to this, with Field Marshall's Lord Mountbatten, Lord Carver and War Office scientific adviser Lord Zuckerman in the Cold War arguing for UK nuclear disarmament and a re-introduction of conscription instead. These guys were not pacifist CND thugs who wanted Moscow to rule the world, but they were quoted by them attacking the deterrent, but not of course quoting them calling for conscription instead. The abolishment of UK conscription for national service announced in 1960 was due to the H-bomb, and was a political money-saving plot by Macmillan. If we disarmed our nuclear deterrent and spend the money on conscription plus underground shelters, we might well be able to resist Russia as Ukraine does, until we run out of ammunition etc. However, the cheapest and most credible deterrent is tactical nuclear weapons to prevent the concentration of aggressive force by terrorist states..)
Duncan Campbell's War Plan UK relies on the contradiction of claiming that the deliberately exaggerated UK Government worst-case civil defense "exercises" for training purposes are "realistic scenarios" (e.g. 1975 Inside Right, 1978 Scrum Half, 1980 Square Leg, 1982 Hard Rock planning), while simultaneously claiming the very opposite about reliable UK Government nuclear effects and sheltering effectiveness data, and hoping nobody would spot his contradictory tactics. He quotes extensively from these lurid worst-case scenario UK civil defense exercises ,as if they are factually defensible rather than imaginary fiction to put planners under the maximum possible stress (standard UK military policy of “Train hard to fight easy”), while ignoring the far more likely limited nuclear uses scenario of Sir John Hackett's Third World War. His real worry is the 1977 UK Government Training Manual for Scientific Advisers which War Plan UK quotes on p14: "a potential threat to the security of the United Kingdom arising from acts of sabotage by enemy agents, possibly assisted by dissident groups. ... Their aim would be to weaken the national will and ability to fight. ... Their significance should not be underestimated." On the next page, War Plan UK quotes J. B. S. Haldane's 1938 book Air Raid Precautions (ARP) on the terrible destruction Haldane witnessed on unprotected people in the Spanish civil war, without even mentioning that Haldane's point is pro-civil defense, pro-shelters, and anti-appeasement of dictatorship, the exact opposite of War Plan UK which wants Russia to run the world. On page 124 War Plan UK the false assertion is made that USA nuclear casualty data is "widely accepted" and true (declassified Hiroshima casaulty data for people in modern concrete buildings proves it to be lies) while the correct UK nuclear casualty data is "inaccurate", and on page 126, Duncan Campbell simply lies that the UK Government's Domestic Nuclear Shelters- Technical Guidance"ended up offering the public a selection of shelters half of which were invented in the Blitz ... None of the designs was ever tested." In fact, Frank Pavry (who studied similar shelters surviving near ground zero at Hiroshima and Nagasaki in 1945 with the British Mission to Japan_ and George R. Stanbury tested 15 Anderson shelters at the first UK nuclear explosion, Operation Hurricane in 1952, together with concrete structures, and many other improvised trench and earth-covered shelters were nuclear tested by USA and UK at trials in 1955, 1956, 1957, and 1958, and later at simulated nuclear explosions by Cresson Kearny of Oak Ridge National Laboratory in the USA, having also earlier been exposed to early Russian nuclear tests (scroll down to see the evidence of this). Improved versions of war tested and nuclear weapons tested shelters! So war Plan UK makes no effort whatsoever to dig up the facts, and instead falsely claims the exact opposite of the plain unvarnished truth! War Plan UK shows its hypocrisy on page 383 in enthusiastically praising Russian civil defense:
"Training in elementary civil defence is given to everyone, at school, in industry or collective farms. A basic handbook of precautionary measures, Everybody must know this!, is the Russian Protect and Survive. The national civil defence corps is extensive, and is organized along military lines. Over 200,000 civil defence troops would be mobilized for rescue work in war. There are said to be extensive, dispersed and 'untouchable' food stockpiles; industrial workers are issued with kits of personal protection apparatus, said to include nerve gas counteragents such as atropine. Fallout and blast shelters are provided in the cities and in industrial complexes, and new buildings have been required to have shelters since the 1950s. ... They suggest that less than 10% - even as little as 5% - of the Soviet population would die in a major attack. [Less than Russia's loss of 12% of its population in WWII.]"
'LLNL achieved fusion ignition for the first time on Dec. 5, 2022. The second time came on July 30, 2023, when in a controlled fusion experiment, the NIF laser delivered 2.05 MJ of energy to the target, resulting in 3.88 MJ of fusion energy output, the highest yield achieved to date. On Oct. 8, 2023, the NIF laser achieved fusion ignition for the third time with 1.9 MJ of laser energy resulting in 2.4 MJ of fusion energy yield. “We’re on a steep performance curve,” said Jean-Michel Di Nicola, co-program director for the NIF and Photon Science’s Laser Science and Systems Engineering organization. “Increasing laser energy can give us more margin against issues like imperfections in the fuel capsule or asymmetry in the fuel hot spot. Higher laser energy can help achieve a more stable implosion, resulting in higher yields.” ... “The laser itself is capable of higher energy without fundamental changes to the laser,” said NIF operations manager Bruno Van Wonterghem. “It’s all about the control of the damage. Too much energy without proper protection, and your optics blow to pieces.” ' - https://lasers.llnl.gov/news/llnls-nif-delivers-record-laser-energy
NOTE: the "problem" very large lasers "required" to deliver ~2MJ (roughly 0.5 kg of TNT energy) to cause larger fusion explosions of 2mm diameter capsules of frozen D+T inside a 1 cm diameter energy reflecting hohlraum, and the "problem" of damage to the equipment caused by the explosions, is immaterial to clean nuclear deterrent development based on this technology, because in a clean nuclear weapon, whatever laser or other power ignition system is used only has to be fired once, so it needs to be less robust than the NIF lasers which are used repeatedly. Similarly, damage done to the system by the explosion is also immaterial for a clean nuclear weapon, in which the weapon is detonated once only! This is exactly the same point which finally occurred during a critical review of the first gun-type assembly nuclear weapon, in which the fact it would only ever be fired once (unlike a field artillery gun) enabled huge reductions in the size of the device, into a practical weapon, as described by General Leslie M. Groves on p163 of his 1962 book Now it can be told: the story of the Manhattan Project:
"Out of the Review Committee's work came one important technical contribution when Rose pointed out ... that the durability of the gun was quite immaterial to success, since it would be destroyed in the explosion anyway. Self-evident as this seemed once it was mentioned, it had not previously occurred to us. Now we could make drastic reductions in ... weight and size."
This principle also applies to weaponizing NIF clean fusion explosion technology. General Groves' book was reprinted in 1982 with a useful Introduction by Edward Teller on the nature of nuclear weapons history: "History in some ways resembles the relativity principle in science. What is observed depends on the observer. Only when the perspective of the observer is known, can proper corrections be made. ... The general ... very often managed to ignore complexity and arrive at a result which, if not ideal, at least worked. ... For Groves, the Manhattan project seemed a minor assignment, less significant than the construction of the Pentagon. He was deeply disappointed at being given the job of supervising the development of an atomic weapon, since it deprived him of combat duty. ... We must find ways to encourage mutual understanding and significant collaboration between those who defend their nation with their lives and those who can contribute the ideas to make that defense successful. Only by such cooperation can we hope that freedom will survive, that peace will be preserved."
General Groves similarly comments in Chapter 31, "A Final Word" of Now it can be told:
"No man can say what would have been the result if we had not taken the steps ... Yet, one thing seems certain - atomic energy would have been developed somewhere in the world ... I do not believe the United States ever would have undertaken it in time of peace. Most probably, the first developer would have been a power-hungry nation, which would then have dominated the world completely ... it is fortunate indeed for humanity that the initiative in this field was gained and kept by the United States. That we were successful was due entirely to the hard work and dedication of the more than 600,000 Americans who comprised and directly supported the Manhattan Project. ... we had the full backing of our government, combined with the nearly infinite potential of American science, engineering and industry, and an almost unlimited supply of people endowed with ingenuity and determination."
Additionally, the test was made in a hurry before an atmospheric teat ban treaty, and this rushed use of a standard air drop steel casing made the tested weapon much heavier than a properly weaponized Ripple II. The key point is that a 10 kt fission device set off a ~10 Mt fusion explosion, a very clean deterrent. Applying this Ripple II 1,000-factor multiplicative staging figure directly to this technology for clean nuclear warheads, a 0.5 kg TNT D+T fusion capsule would set off a 0.5 ton TNT 2nd stage of LiD, which would then set off a 0.5 kt 3rd stage "neutron bomb", which could then be used to set off a 500 kt 4th stage or "strategic nuclear weapon". In practice, this multiplication factor of 1,000 given by Ripple II in 1962 from 10 kt to 10 Mt may not be immediately achievable to get from ~1 kg TNT yield to 1 ton TNT, so a few more tiny stages may be needed for the lower yield. But there is every reason to forecast that with enough research, improvements will be possible and the device will become a reality. It is therefore now possible not just in "theory" or in principle, but with evidence obtained from practical experimentation, using suitable already-proved technical staging systems used in 1960s nuclear weapon tests successfully, to design 100% clean fusion nuclear warheads! Yes, the details have been worked out, yes the technology has been tested in piecemeal fashion. All that is now needed is a new, but quicker and cheaper, Star Wars program or Manhattan Project style effort to pull the components together. This will constitute a major leap forward in the credibility of the deterrence of aggressors.
ABOVE: as predicted, the higher the input laser pulse for the D+T initiator of a clean multiplicatively-staged nuclear deterrent, the lower the effect of plasma instabilities and asymmetries and the greater the fusion burn. To get ignition (where the x-ray energy injected into the fusion hohlraum by the laser is less than the energy released in the D+T fusion burn) they have had to use about 2 MJ delivered in 10 ns or so, equivalent to 0.5 kg of TNT equivalent. But for deterrent use, why use such expensive, delicate lasers? Why not just use one-shot miniaturised x-ray tubes with megavolt electron acceleration, powered a suitably ramped pulse from a chemical explosion for magnetic flux compression current generation? At 10% efficiency, you need 0.5 x 10 = 5 kg of TNT! Even at 1% efficiency, 50 kg of TNT will do. Once the D+T gas capsule's hohlraum is well over 1 cm in size, to minimise the risk of imperfections that cause asymmetries, you don't any longer need focussed laser beams to enter tiny apertures. You might even be able to integrate many miniature flash x-ray tubes (each designed to burn out when firing one pulse of a MJ or so) into a special hohlraum. Humanity urgently needs a technological arms race akin to Reagan's Star Wars project, to deter the dictators from invasions and WWIII. In the conference video above, a question was asked about the real efficiency of the enormous repeat-pulse capable laser system's efficiency (not required for a nuclear weapon whose components only require the capability to be used once, unlike lab equipment): the answer is that 300 MJ was required by the lab lasers to fire a 2 MJ pulse into the D+T capsule's x-ray hohlraum, i.e. their lasers are only 0.7% efficient! So why bother? We know - from the practical use of incoherent fission primary stage x-rays to compress and ignite fusion capsules in nuclear weapons - that you simply don't need coherent photons from a laser for this purpose. The sole reason they are approaching the problem with lasers is that they began their lab experiments decades ago with microscopic sized fusion capsules and for those you need a tightly focussed beam to insert energy through a tiny hohlraum aperture. But now they are finally achieving success with much larger fusion capsules (to minimise instabilities that caused the early failures), it may be time to change direction. A whole array of false "no-go theorems" can and will be raised by ignorant charlatan "authorities" against any innovation; this is the nature of the political world. There is some interesting discussion of why clean bombs aren't in existence today, basically the idealized theory (which works fine for big H-bombs but ignores small-scale asymmetry problems which are important only at low ignition energy) understimated the input energy required for fusion ignition by a factor of 2000:
In the final diagram above, we illustrate an example of what could very well occur in the near future, just to really poke a stick into the wheels of "orthodoxy" in nuclear weapons design: is it possible to just use a lot of (perhaps hardened for higher currents, perhaps no) pulsed current driven microwave tubes from kitchen microwave ovens, channelling their energy using waveguides (simply metal tubes, i.e. electrical Faraday cages, which reflect and thus contain microwaves) into the hohlraum, and make the pusher of dipole molecules (like common salt, NaCl) which is a good absorber of microwaves (as everybody knows from cooking in microwave ovens)? It would be extremely dangerous, not to mention embarrassing, if this worked, but nobody had done any detailed research into the possibility due to groupthink orthodoxy and conventional boxed in thinking! Remember, the D+T capsule just needs extreme compression and this can be done by any means that works. Microwave technology is now very well-established. It's no good trying to keep anything of this sort "secret" (either officially or unofficially) since as history shows, dictatorships are the places where "crackpot"-sounding ideas (such as douple-primary Project "49" Russian thermonuclear weapon designs, Russian Sputnik satellites, Russian Novichok nerve agent, Nazi V1 cruise missiles, Nazi V2 IRBM's, etc.) can be given priority by loony dictators. We have to avoid, as Edward Teller put it (in his secret commentary debunking Bethe's false history of the H-bomb, written AFTER the Teller-Ulam breakthrough), "too-narrow" thinking (which Teller said was still in force on H-bomb design even then). Fashionable hardened orthodoxy is the soft underbelly of "democracy" (a dictatorship by the majority, which is always too focussed on fashionable ideas and dismissive of alternative approaches in science and technology). Dictatorships (minorities against majorities) have repeatedly demonstrated a lack of concern for the fake "no-go theorems" used by Western anti-nuclear "authorities" to ban anything but fashionable groupthink science.
ABOVE: 1944-dated film of the Head of the British Mission to Los Alamos, neutron discoverer James Chadwick, explaining in detail to American how hard it was for him to discover the neutron, taking 10 years on a shoe-string budget, mostly due to having insufficiently strong sources of alpha particles to bombard nuclei in a cloud chamber! The idea of the neutron came from his colleague Rutherford. Chadwick reads his explanation while rapidly rotating a pencil in his right hand, perhaps indicating the stress he was under in 1944. In 1946, when British participation at Los Alamos ended, Chadwick wrote the first detailed secret British report on the design of a three-stage hydrogen bomb, another project that took over a decade. In the diagram below, it appears that the American Mk17 only had a single secondary stage like the similar yield 1952 Mike design. The point here is that popular misunderstanding of the simple mechanism of x-ray energy transfer for higher yield weapons may be creating a dogmatic attitude even in secret nuclear weaponeer design labs, where orthodoxy is followed too rigorously. The Russians (see quotes on the latest blog post here) state they used two entire two-stage thermonuclear weapons with a combined yield of 1 megaton to set off their 50 megaton test in 1961. If true, you can indeed use two-stage hydrogen bombs as an "effective primary" to set off another secondary stage, of much higher yield. Can this be reversed in the sense of scaling it down so you have several bombs-within-bombs, all triggered by a really tiny first stage? In other words, can it be applied to neutron bomb design?
The 1946 Report of the British Mission to Japan, The Effects of the Atomic Bombs at Hiroshima and Nagasaki, compiled by a team of 16 in Hiroshima and Nagasaki during November 1945, which included 10 UK Home Office civil defence experts (W. N. Thomas, J. Bronowski, D. C. Burn, J. B. Hawker, H. Elder, P. A. Badland, R. W. Bevan, F. H. Pavry, F. Walley, O. C. Young, S. Parthasarathy, A. D. Evans, O. M. Solandt, A. E. Dark, R. G. Whitehead and F. G. S. Mitchell) found: "Para. 26. Reinforced concrete buildings of very heavy construction in Hiroshima, even when within 200 yards of the centre of damage, remained structurally undamaged. ... Para 28. These observations make it plain that reinforced concrete framed buildings can resist a bomb of the same power detonated at these heights, without employing fantastic thicknesses of concrete. ... Para 40. The provision of air raid shelters throughout Japan was much below European standards. ... in Hiroshima ... they were semi-sunk, about 20 feet long, had wooden frames, and 1.5-2 feet of earth cover. ... Exploding so high above them, the bomb damaged none of these shelters. ... Para 42. These observations show that the standard British shelters would have performed well against a bomb of the same power exploded at such a height. Anderson shelters, properly erected and covered, would have given protection. Brick or concrete surfac shelters with adequate reinforcement would have remained safe from collapse. The Morrison shelter is designed only to protect its occupants from the refuge load of a house, and this it would have done. Deep shelters such as the refuge provided by the London Underground would have given complete protection. ... Para 60. Buildings and walls gave complete protection from flashburn."
Glasstone and Dolan's 1977 Effects of Nuclear Weapons in Table 12.21 on p547 flunks making this point by giving data without citing its source to make it credible to readers: it correlated 14% mortality (106 killed out of 775 people in Hiroshima's Telegraph Office) to "moderate damage" at 500m in Hiroshima (the uncited "secret" source was NP-3041, Table 12, applying to unwarned people inside modern concrete buildings).
"A weapon whose basic design would seem to provide the essence of what Western morality has long sought for waging classical battlefield warfare - to keep the war to a struggle between the warriors and exclude the non-combatants and their physical assets - has been violently denounced, precisely because it achieves this objective." - Samuel T. Cohen (quoted in Chapman Pincher, The secret offensive, Sidgwick and Jackson, London, 1985, Chapter 15: The Neutron Bomb Offensive, p210).
The reality is, dedicated enhanced neutron tactical nuclear weapons were used to credibly deter the concentrations of force required for triggering of WWIII during the 1st Cold War, and the thugs who support Russian propaganda for Western disarmament got rid of them on our side, but not on the Russian side. Air burst neutron bombs or even as subsurface earth penetrators of relatively low fission yield (where the soil converts energy that would otherwise escape as blast and radiation into ground shock for destroying buried tunnels - new research on cratering shows that a 20 kt subsurface burst creates similar effects on buried hard targets as a 1 Mt surface burst), they cause none of the vast collateral damage to civilians that we see now in Ukraine and Gaza, or that we saw in WWII and the wars in Korea and Vietnam. This is 100% contrary to CND propaganda which is a mixture of lying on nuclear explosion collateral damage, escalation/knockout blow propaganda (of the type used to start WWII by appeasers) and lying on the designs of nuclear weapons in order to ensure the Western side (but not the thugs) gets only incredible "strategic deterrence" that can't deter the invasions that start world wars (e.g. Belgium in 1914 and Poland in 1939.) "Our country entered into an agreement in Budapest, Hungary when the Soviet Union was breaking up that we would guarantee the independence of Ukraine." - Tom Ramos. There really is phoney nuclear groupthink left agenda politics at work here: credible relatively clean tactical nuclear weapons are banned in the West but stocked by Russia, which has civil defense shelters to make its threats far more credible than ours! We need low-collateral damage enhanced-neutron and earth-penetrator options for the new Western W93 warhead, or we remain vulnerable to aggressive coercion by thugs, and invite invasions. Ambiguity, the current policy ("justifying" secrecy on just what we would do in any scenario) actually encourages experimental provocations by enemies to test what we are prepared to do (if anything), just as it did in 1914 and the 1930s.
ABOVE: 0.2 kt (tactical yield range) Ruth nuclear test debris, with lower 200 feet of the 300 ft steel tower surviving in Nevada, 1953. Note that the yield of the tactical invasion-deterrent Mk54 Davy Crockett was only 0.02 kt, 10 times less than than 0.2 kt Ruth.
It should be noted that cheap and naive "alternatives" to credible deterrence of war were tried in the 1930s and during the Cold War and afterwards, with disastrous consequences. Heavy "peaceful" oil sanctions and other embargoes against Japan for its invasion of China between 1931-7 resulted in the plan for the Pearl Harbor surprise attack of 7 December 1941, with subsequent escalation to incendiary city bombing followed nuclear warfare against Hiroshima and Nagasaki. Attlee's pressure on Truman to guarantee no use of tactical nuclear weapons in the Korean War (leaked straight to Stalin by the Cambridge Spy Ring), led to an escalation of that war causing the total devastation of the cities of that country by conventional bombing (a sight witnessed by Sam Cohen, that motivated his neutron bomb deterrent of invasions), until Eisenhower was elected and reversed Truman's decision, leading not to the "escalatory Armageddon" assertions of Attlee, but to instead to a peaceful armistice! Similarly, as Tom Ramos argues in From Berkeley to Berlin: How the Rad Lab Helped Avert Nuclear War, Kennedy's advisers who convinced him to go ahead with the moonlit 17 April 1961 Bay of Pigs invasion of Cuba without any USAF air support, which led to precisely what they claimed they would avoid: an escalation of aggression from Russia in Berlin, with the Berlin Wall going up on 17 August 1961 because any showing weakness to an enemy, as in the bungled invasion of Cuba, is always a green light to dictators to go ahead with revolutions, invasions and provocations everywhere else. Rather than the widely hyped autistic claims from disarmers and appeasers about "weakness bringing peace by demonstrating to the enemy that they have nothing to fear from you", the opposite result always occurs. The paranoid dictator seizes the opportunity to strike first. Similarly, withdrawing from Afghanistan in 2021 was a clear green light to Russia to go ahead with a full scale invasion of Ukraine, reigniting the Cold War. von Neumann and Morgenstein's Minimax theorem for winning games - minimise the maximum possible loss - fails with offensive action in war because it sends a signal of weakness to the enemy, which does not treat war as a game with rules to be obeyed. Minimax is only valid for defense, such as civil defense shelters used by Russia to make their threats more credible than ours. The sad truth is that cheap fixes don't work, no matter how much propaganda is behind them. You either need to militarily defeat the enemy or at least economically defeat them using proven Cold War arms race techniques (not merely ineffective sanctions, which they can bypass by making alliances with Iran, North Korea, and China). Otherwise, you are negotiating peace from a position of weakness, which is called appeasement, or collaboration with terrorism.
"Following the war, the Navy Department was intent to see the effects of an atomic blast on naval warships ... the press was invited to witness this one [Crossroads-Able, 23.5 kt at 520 feet altitude, 1 July 1946, Bikini Atoll]. ... The buildup had been too extravagant. Goats that had been tethered on warship decks were still munching their feed, and the atoll's palm trees remained standing, unscathed. The Bikini test changed public attitudes. Before July 1, the world stood in awe of a weapon that had devastated two cities and forced the Japanese Empire to surrender. After that date, the bomb was still a terrible weapon, but a limited one." - Tom Ramos (LLNL nuclear weaponeer and nuclear pumped X-ray laser developer), From Berkeley to Berlin: How the Rad Lab Helped Prevent Nuclear War, Naval Institute Press, 2022, pp43-4.
ILLUSTRATION: the threat of WWII and the need to deter it was massively derided by popular pacifism which tended to make "jokes" of the Nazi threat until too late (example of 1938 UK fiction on this above; Charlie Chaplin's film "The Great Dictator" is another example), so three years after the Nuremberg Laws and five years after illegal rearmament was begun by the Nazis, in the UK crowds of "pacifists" in Downing Street, London, support friendship with the top racist, dictatorial Nazis in the name of "world peace". The Prime Minister used underhand techniques to try to undermine appeasement critics like Churchill and also later to get W. E. Johns fired from both editorships of Flying (weekly) and Popular Flying (monthly) to make it appear everybody "in the know" agreed with his actions, hence the contrived "popular support" for collaborating with terrorists depicted in these photos. The same thing persists today; the 1920s and 1930s "pacifist" was also driven by "escalation" and "annihilation" claims explosions, fire and WMD poison gas will kill everybody in a "knockout blow", immediately any war breaks out.
"Fuchs reasoned that [the very low energy, 1-10 kev, approximately 10-100 lower energy than medical] x-rays from the [physically separated] uranium explosion would reach the tamper of beryllium oxide, heat it, ionize the constituents and cause them to implode - the 'ionization implosion' concept of von Neumann but now applied to deuterium and tritium contained within beryllium oxide. To keep the radiation inside the tamper, Fuchs proposed to enclose the device inside a casing impervious to radiation. The implosion induced by the radiation would amplify the compression ... and increase the chance of the fusion bomb igniting. The key here is 'separation of the atomic charge and thermonuclear fuel, and compression of the latter by radiation travelling from the former', which constitutes 'radiation implosion'." (This distinction between von Neumann's "ionization implosion" INSIDE the tamper, of denser tamper expanding and thus compressing lower density fusion fuel inside, and Fuchs' OUTSIDE capsule "radiation implosion", is key even today for isentropic H-bomb design; it seems Teller's key breakthroughs were not separate stages or implosion but rather radiation mirrors and ablative recoil shock compression, where radiation is used to ablate a dense pusher of Sausage designs like Mike in 1952 etc., a distinction not to be confused for the 1944 von Neumann and 1946 Fuchs implosion mechanisms!
It appears Russian H-bombs used von Neumann's "ionization implosion" and Fuchs's "radiation implosion" for RDS-37 on 22 November 1955 and also in their double-primary 23 February 1958 test and subsequently, where their fusion capsules reportedly contained a BeO or other low-density outer coating, which would lead to quasi-isentropic compression, more effective for low density secondary stages than purely ablative recoil shock compression. This accounts for the continuing classification of the April 1946 Superbomb Conference (the extract of 32 pages linked here is so severely redacted that it is less helpful than the brief but very lucid summary of its technical content, in the declassified FBI compilation of reports concerning data Klaus Fuchs sent to Stalin, linked here!). Teller had all the knowledge he needed in 1946, but didn't go ahead because he made the stupid error of killing progress off by his own "no-go theorem" against compression of fusion fuel. Teller did a "theoretical" calculation in which he claimed that compression has no effect on the amount of fusion burn because the compressed system is simply scaled down in size so that the same efficiency of fusion burn occurs, albeit faster, and then stops as the fuel thermally expands. This was wrong. Teller discusses the reason for his great error in technical detail during his tape-recorded interview by Chuck Hansen at Los Alamos on 7 June 1993 (C. Hansen, Swords of Armageddon, 2nd ed., pp. II-176-7):
"Now every one of these [fusion] processes varied with the square of density. If you compress the thing, then in one unit's volume, each of the 3 important processes increased by the same factor ... Therefore, compression (seemed to be) useless. Now when ... it seemed clear that we were in trouble, then I wanted very badly to find a way out. And it occurred to be than an unprecedentedly strong compression will just not allow much energy to go into radiation. Therefore, something had to be wrong with my argument and then, you know, within minutes, I knew what must be wrong ... [energy] emission occurs when an electron and a nucleus collide. Absorption does not occur when a light quantum and a nucleus ... or ... electron collide; it occurs when a light quantum finds an electron and a nucleus together ... it does not go with the square of the density, it goes with the cube of the density." (This very costly theoretical error, wasting five years 1946-51, could have been resolved by experimental nuclear testing. There is always a risk of this in theoretical physics, which is why experiments are done to check calculations before prizes are handed out. The ban on nuclear testing is a luddite opposition to technological progress in improving deterrence.)
(This 1946-51 theoretical "no-go theorem" anti-compression error of Teller's, which was contrary to the suggestion of compression at the April 1946 superbomb conference as Teller himself refers to on 14 August 1952, and which was corrected only by comparison of the facts about compression validity in pure fission cores in Feb '51 after Ulam's argument that month for fission core compression by lens focussed primary stage shock waves, did not merely lead to Teller's dismissal of vital compression ideas. It also led to his false equations - exaggerating the cooling effect of radiation emission - causing underestimates of fusion efficiency in all theoretical calculations done of fusion until 1951! For this reason, Teller later repudiated the calculations that allegedly showed his Superbomb would fizzle; he argued that if it had been tested in 1946, the detailed data obtained - regardless of whatever happened - would have at least tested the theory which would have led to rapid progress, because the theory was wrong. The entire basis of the cooling of fusion fuel by radiation leaking out was massively exaggerated until Lawrence Livermore weaponeer John Nuckolls showed that there is a very simple solution: use baffle re-radiated, softened x-rays for isentropic compression of low-density fusion fuel, e.g. very cold 0.3 kev x-rays rather than the usual 1-10 kev cold-warm x-rays emitted directly from the fission primary. Since the radiation losses are proportional to the fourth-power of the x-ray energy or temperature, losses are virtually eliminated, allowing very efficient staging as for Nuckolls' 99.9% 10 Mt clean Ripple II, detonated on 30 October 1962 at Christmas Island. Teller's classical Superbomb was actually analyzed by John C. Solem in a 15 December 1978 report, A modern analysis of Classical Super, LA-07615, according to a Freedom of Information Act request filed by mainstream historian Alex Wellerstein, FOIA 17-00131-H, 12 June 2017; according to a list of FOIA requests at https://www.governmentattic.org/46docs/NNSAfoiaLogs_2016-2020.pdf. However, a google search for the documents Dr Wellerstein requested shows only a few at the US Gov DOE Opennet OSTI database or otherwise online yet e.g. LA-643 by Teller, On the development of Thermonuclear Bombs dated 16 Feb. 1950. The page linked here stating that report was "never classified" is mistaken! One oddity about Teller's anti-compression "no-go theorem" is that the even if fusion rates were independent of density, you would still want compression of fissile material in a secondary stage such as a radiation imploded Alarm Clock, because the whole basis of implosion fission bombs is the benefit of compression; another issue is that even if fusion rates are unaffected by density, inward compression would still help to delay the expansion of the fusion system which leads to cooling and quenching of the fusion burn.)
In fact (see Lawrence Livermore National Laboratory nuclear warhead designer Nuckolls' explanation in report UCRL-74345): "The rates of burn, energy deposition by charged reaction products, and electron-ion heating are proportional to the density, and the inertial confinement time is proportional to the radius. ... The burn efficiency is proportional to the product of the burn rate and the inertial confinement time ...", i.e. the fusion burn rate is directly proportional to the fuel density, which in turn is of course inversely proportional to the cube of its radius. But the inertial confinement time for fusion to occur is proportional to the radius, so the fusion stage efficiency in a nuclear weapon is the product of the burn rate (i.e., 1/radius^3) and time (i.e., radius), so efficiency ~ radius/(radius^3) ~ 1/radius^2. Therefore, for a given fuel temperature, the total fusion burn, or the efficiency of the fusion stage, is inversely proportional to the square of the compressed radius of the fuel! (Those condemning Teller's theoretical errors or "arrogance" should be aware that he pushed hard all the time for experimental nuclear tests of his ideas, to check if they were correct, exactly the right thing to do scientifically and others who read his papers had the opportunity to point out any theoretical errors, but was rebuffed by those in power, who used a series of contrived arguments to deny progress, based upon what Harry would call "subconscious bias", if not arrogant, damning, overt bigotry against the kind of credible, overwhelming deterrence which had proved lacking a decade earlier, leading to WWII. This callousness towards human suffering in war and under dictatorship existed in some UK physicists too: Joseph Rotblat's hatred of anything to deter Russia be it civil defense or tactical neutron bombs of the West - he had no problem smiling and patting Russia's neutron bomb when visiting their labs during cosy groupthink deluded Pugwash campaigns for Russian-style "peaceful collaboration" - came from deep family communist convictions, since his brother was serving in the Red Army in 1944 when he alleged he heard General Groves declare that the bomb must deter Russia! Rotblat stated he left Los Alamos as a result. The actions of these groups are analogous to the "Cambridge Scientists Anti-War Group" in the 1930s. After Truman ordered a H-bomb, Bradbury at Los Alamos had to start a "Family Committee" because Teller had a whole "family" of H-bomb designs, ranging from the biggest, "Daddy", through various "Alarm Clocks", all the way down to small internally-boosted fission tactical weapons. From Teller's perspective, he wasn't putting all eggs in one basket.)
There is more to Fuchs' influence on the UK H-bomb than I go into that paper; Chapman Pincher alleged that Fuchs was treated with special leniency at his trial and later he was given early release in 1959 because of his contributions and help with the UK H-bomb as author of the key Fuchs-von Neumann x-ray compression mechanism patent. For example, Penney visited Fuchs in June 1952 in Stafford Prison; see pp309-310 of Frank Close's 2019 book "Trinity". Close argues that Fuchs gave Penney a vital tutorial on the H-bomb mechanism during that prison visit. That wasn't the last help, either, since the UK Controller for Atomic Energy Sir Freddie Morgan wrote Penney on 9 February 1953 that Fuchs was continuing to help. Another gem: Close gives, on p396, the story of how the FBI became suspicious of Edward Teller, after finding a man of his name teaching at the NY Communist Workers School in 1941 - the wrong Edward Teller, of course - yet Teller's wife was indeed a member of the Communist-front "League of women shoppers" in Washington, DC.
Chapman Pincher, who attended the Fuchs trial, writes about Fuchs hydrogen bomb lectures to prisoners in chapter 19 of his 2014 autobiography, Dangerous to know (Biteback, London, pp217-8): "... Donald Hume ... in prison had become a close friend of Fuchs ... Hume had repaid Fuchs' friendship by organising the smuggling in of new scientific books ... Hume had a mass of notes ... I secured Fuchs's copious notes for a course of 17 lectures ... including how the H-bomb works, which he had given to his fellow prisoners ... My editor agreed to buy Hume's story so long as we could keep the papers as proof of its authenticity ... Fuchs was soon due for release ..."
Chapman Pincher wrote about this as the front page exclusive of the 11 June 1952 Daily Express, "Fuchs: New Sensation", the very month Penney visited Fuchs in prison to receive his H-bomb tutorial! UK media insisted this was evidence that UK security still wasn't really serious about deterring further nuclear spies, and the revelations finally culminated in the allegations that the MI5 chief 1956-65 Roger Hollis was a Russian fellow-traveller (Hollis was descended from Peter the Great, according to his elder brother Chris Hollis' 1958 book Along the Road to Frome) and GRU agent of influence, codenamed "Elli". Pincher's 2014 book, written aged 100, explains that former MI5 agent Peter Wright suspected Hollis was Elli after evidence collected by MI6 agent Stephen de Mowbray was reported to the Cabinet Secretary. Hollis is alleged to have deliberately fiddled his report of interviewing GRU defector Igor Gouzenko on 21 November 1945 in Canada. Gouzenko had exposed the spy and Groucho Marx lookalike Dr Alan Nunn May (photo below), and also a GRU spy in MI5 codenamed Elli, who used only duboks (dead letter boxes), but Gouzenko told Pincher that when Hollis interviewed him in 1945 he wrote up a lengthy false report claiming to discredit many statements by Gouzenko: "I could not understand how Hollis had written so much when he had asked me so little. The report was full of nonsense and lies. As [MI5 agent Patrick] Stewart read the report to me [during the 1972 investigation of Hollis], it became clear that it had been faked to destroy my credibility so that my information about the spy in MI5 called Elli could be ignored. I suspect that Hollis was Elli." (Source: Pincher, 2014, p320.) Christopher Andrew claimed Hollis couldn't have been GRU spy Elli because KGB defector Oleg Gordievsky suggested it was the KGB spy Leo Long (sub-agent of KGB spy Anthony Blunt). However, Gouzenko was GRU, not KGB like Long and Gordievsky! Gordievsky's claim that "Elli" was on the cover of Long's KGB file was debunked by KGB officer Oleg Tsarev, who found that Long's codename was actually Ralph! Another declassified Russian document, from General V. Merkulov to Stalin dated 24 Nov 1945, confirmed Elli was a GRU agent inside british intelligence, whose existence was betrayed by Gouzenko. In Chapter 30 of Dangerous to Know, Pincher related how he was given a Russian suitcase sized microfilm enlarger by 1959 Hollis spying eyewitness Michael J. Butt, doorman for secret communist meetings in London. According to Butt, Hollis delivered documents to Brigitte Kuczynski, younger sister of Klaus Fuchs' original handler, the notorious Sonia aka Ursula. Hollis allegedly provided Minox films to Brigitte discretely when walking through Hyde Park at 8pm after work. Brigitte gave her Russian made Minox film enlarger to Butt to dispose of, but he kept it in his loft as evidence. (Pincher later donated it to King's College.) Other more circumstantial evidence is that Hollis recruited the spy Philby, Hollis secured spy Blunt immunity from prosecution, Hollis cleared Fuchs in 1943, and MI5 allegedly destroyed Hollis' 1945 interrogation report on Gouzenko, to prevent the airing of the scandal that it was fake after checking it with Gouzenko in 1972.
It should be noted that the very small number of Russian GRU illegal agents in the UK and the very small communist party membership had a relatively large influence on nuclear policy via infiltration of unions which had block votes in the Labour Party, as well the indirect CND and "peace movement" lobbies saturating the popular press with anti-civil defence propaganda to make the nuclear deterrent totally incredible for any provocation short of a direct all-out countervalue attack. Under such pressure, UK Prime Minister Harold Wilson's government abolished the UK Civil Defence Corps, making the UK nuclear deterrent totally incredible against major provocations, in March 1968. While there was some opposition to Wilson, it was focussed on his profligate nationalisation policies which were undermining the economy and thus destabilizing military expenditure for national security. Peter Wright’s 1987 book Spycatcher and various other sources, including Daily Mirror editor Hugh Cudlipp's book Walking on Water, documented that on 8 May 1968, the Bank of England's director Cecil King, who was also Chairman of Daily Mirror newspapers, Mirror editor Cudlipp and the UK Ministry of Defence's anti-nuclear Chief Scientific Adviser Sir Solly Zuckerman, met at Lord Mountbatten's house in Kinnerton Street, London, to discuss a coup e'tat to overthrow Wilson and make Mountbatten the UK President, a new position. King's position, according to Cudlipp - quite correctly as revealed by the UK economic crises of the 1970s when the UK was effectively bankrupt - was that Wilson was setting the UK on the road to financial ruin and thus military decay. Zuckerman and Mountbatten refused to take part in a revolution, however Wilson's government was attacked by the Daily Mirror in a front page editorial by Cecil King two days later, on 10 May 1968, headlined "Enough is enough ... Mr Wilson and his Government have lost all credibility, all authority." According to Wilson's secretary Lady Falkender, Wilson was only told of the coup discussions in March 1976.
CND and the UK communist party alternatively tried to claim, in a contradictory way, that they were (a) too small in numbers to have any influence on politics, and (b) they were leading the country towards utopia via unilateral nuclear disarmament saturation propaganda about nuclear weapons annihilation (totally ignoring essential data on different nuclear weapon designs, yields, heights of burst, the "use" of a weapon as a deterrent to PREVENT an invasion of concentrated force, etc.) via the infiltrated BBC and most other media. Critics pointed out that Nazi Party membership in Germany was only 5% when Hitler became dictator in 1933, while in Russia there were only 200,000 Bolsheviks in September 1917, out of 125 million, i.e. 0.16%. Therefore, the whole threat of such dictatorships is a minority seizing power beyond it justifiable numbers, and controlling a majority which has different views. Traditional democracy itself is a dictatorship of the majority (via the ballot box, a popularity contest); minority-dictatorship by contrast is a dictatorship by the fanatically motivated minority by force and fear (coercion) to control the majority. The coercion tactics used by foreign dictators to control the press in free countries are well documented, but never publicised widely. Hitler put pressure on Nazi-critics in the UK "free press" via UK Government appeasers Halifax, Chamberlain and particularly the loathsome UK ambassador to Nazi Germany, Sir Neville Henderson, for example trying to censor or ridicule appeasement critics David Low, to fire Captain W. E. Johns (editor of both Flying and Popular Flying, which had huge circulations and attacked appeasement as a threat to national security in order to reduce rearmament expenditure), and to try to get Winston Churchill deselected. These were all sneaky "back door" pressure-on-publishers tactics, dressed up as efforts to "ease international tensions"! The same occurred during the Cold War, with personal attacks in Scientific American and Bulletin of the Atomic Scientists and by fellow travellers on Herman Kahn, Eugene Wigner, and others who warned we need civil defence to make a deterrent of large provocations credible in the eyes of an aggressor.
Chapman Pincher summarises the vast hypocritical Russian expenditure on anti-Western propaganda against the neutron bomb in Chapter 15, "The Neutron Bomb Offensive" of his 1985 book The Secret Offensive: "Such a device ... carries three major advantages over Hiroshima-type weapons, particularly for civilians caught up in a battle ... against the massed tanks which the Soviet Union would undoubtedly use ... by exploding these warheads some 100 feet or so above the massed tanks, the blast and fire ... would be greatly reduced ... the neutron weapon produces little radioactive fall-out so the long-term danger to civilians would be very much lower ... the weapon was of no value for attacking cities and the avoidance of damage to property can hardly be rated as of interest only to 'capitalists' ... As so often happens, the constant repetition of the lie had its effects on the gullible ... In August 1977, the [Russian] World Peace Council ... declared an international 'Week of action' against the neutron bomb. ... Under this propaganda Carter delayed his decision, in September ... a Sunday service being attended by Carter and his family on 16 October 1977 was disrupted by American demonstrators shouting slogans against the neutron bomb [see the 17 October 1977 Washington Post] ... Lawrence Eagleburger, when US Under Secretary of State for Political Affairs, remarked, 'We consider it probably that the Soviet campaign against the 'neutron bomb cost some $100 million'. ... Even the Politburo must have been surprised at the size of what it could regard as a Fifth Column in almost every country." [Unfortunately, Pincher himself had contributed to the anti-nuclear nonsense in his 1965 novel "Not with a bang" in which small amounts of radioactivity from nuclear fallout combine with medicine to exterminate humanity! The allure of anti-nuclear propaganda extends to all who which to sell "doomsday fiction", not just Russian dictators but mainstream media story tellers in the West. By contrast, Glasstone and Dolan's 1977 Effects of Nuclear Weapons doesn't even mention the neutron bomb, so there was no scientific and technical effort whatsoever by the West to make it a credible deterrent even in the minds of the public it had to protect from WWIII!]
So why on earth doesn't the West take the cheap efficient option of cutting expensive oralloy and maximising cheap natural (mostly lithium-7) LiD in the secondary? Even Glasstone's 1957 Effects of Nuclear Weapons on p17 (para 1.55) states that "Weight for weight ... fusion of deuterium nuclei would produce nearly 3 times as much energy as the fission of uranium or plutonium"! The sad answer is "density"! Natural LiD (containing 7.42% Li6 abundance) is a low density white/grey crystalline solid like salt that actually floats on water (lithium deuteroxide would be formed on exposure to water), since its density is just 820 kg/m^3. Since the ratio of mass of Li6D to Li7D is 8/9, it would be expected that the density of highly enriched 95% Li6D is 739 kg/m^3, while for 36% enriched Li6D it is 793 kg/m^3. Uranium metal has a density of 19,000 kg/m^3, i.e. 25.7 times greater than 95% enriched li6D or 24 times greater than 36% enriched Li6D. Compactness, i.e. volume is more important in a Western MIRV warhead than mass/weight! In the West, it's best to have a tiny-volume, very heavy, very expensive warhead. In Russia, cheapness outweights volume considerations. The Russians in some cases simply allowed their more bulky warheads to protrude from the missile bus (see photo below), or compensated for lower yields at the same volume using clean LiD by using the savings in costs to build more warheads. (The West doubles the fission yield/mass ratio of some warheads by using U235/oralloy pushers in place of U238, which suffers from the problem that about half the neutrons it interacts with result in non-fission capture, as explained below. Note that the 720 kiloton UK nuclear test Orange Herald device contained a hollow shell of 117 kg of U235 surrounded by a what Lorna Arnold's book quotes John Corner referring to a "very thin" layer of high explosive, and was compact, unboosted - the boosted failed to work - and gave 6.2 kt/kg of U235, whereas the first version of the 2-stage W47 Polaris warhead contained 60 kg of U235 which produced most of the secondary stage yield of about 400 kt, i.e. 6.7 kt/kg of U235. Little difference - but because perhaps 50% of the total yield of the W47 was fusion, its efficiency of use of U235 must have actually been less than the Orange Herald device, around 3 kt/kg of U235 which indicates design efficiency limits to "hydrogen bombs"! Yet anti-nuclear charlatans claimed that the Orange Herald bomb was a con!)

(In order to analyze the warhead pusher thicknesses and very basic schematics from this table it is necessary to supplement it with the 1950s warhead design data declassified in other documents, particularly some of the data from Tom Ramos and Chuck Hansen, as quoted in some detail below.) The data on the mass of special nuclear materials in each of the different weapons argues strongly that the entire load of Pu239 and U235 in the 1.1 megaton B28 was in the primary stage, so that weapon could not have had a fissile spark plug in the centre let alone a fissile ablator (unlike Teller's Sausage design of 1951), and so the B28 it appears had no need whatsoever of a beryllium neutron radiation shield to prevent pre-initiation of the secondary stage prior to its compression (on the contrary, such neutron exposure of the lithium deuteride in the secondary stage would be VITAL to produce some tritium in it prior to compression, to spark fusion when it was compressed). Arnold's book indeed explains that UK AWE physicists found the B28 to be an excellent, highly optimised, cheap design, unlike the later W47 which was extremely costly. The masses of U235 and Li6 in the W47 shows the difficulties of trying to maintain efficiency while scaling down the mass of a two-stage warhead for SLBM delivery: much larger quantities of Li6 and U235 must be used to achieve a LOWER yield! To achieve thermonuclear warheads of low mass at sub-megaton yields, both the outer bomb casing and the pusher around the the fusion fuel must be reduced:
"York ... studied the Los Alamos tests in Castle and noted most of the weight in thermonuclear devices was in their massive cases. Get rid of the case .... On June 12, 1953, York had presented a novel concept ... It radically altered the way radiative transport was used to ignite a secondary - and his concept did not require a weighty case ... they had taken the Teller-Ulam concept and turned it on its head ... the collapse time for the new device - that is, the amount of time it took for an atomic blast to compress the secondary - was favorable compared to older ones tested in Castle. Brown ... gave a female name to the new device, calling it the Linda." - Dr Tom Ramos (Lawrence Livermore National Laboratory nuclear weapon designer), From Berkeley to Berlin: How the Rad Lab Helped Avert Nuclear War, Naval Institute press, 2022, pp137-8. (So if you reduce the outer casing thickness to reduce warhead weight, you must complete the pusher ablation/compression faster, before the thinner outer casing is blown off, and stops reflecting/channelling x-rays on the secondary stage. Making the radiation channel smaller and ablative pusher thinner helps to speed up the process. Because the ablative pusher is thinner, there is relatively less blown-off debris to block the narrower radiation channel before the burn ends.)
"Brown's third warhead, the Flute, brought the Linda concept down to a smaller size. The Linda had done away with a lot of material in a standard thermonuclear warhead. Now the Flute tested how well designers could take the Linda's conceptual design to substantially reduce not only the weight but also the size of a thermonuclear warhead. ... The Flute's small size - it was the smallest thermonuclear device yet tested - became an incentive to improve codes. Characteristics marginally important in a larger device were now crucially important. For instance, the reduced size of the Flute's radiation channel could cause it to close early [with ablation blow-off debris], which would prematurely shut off the radiation flow. The code had to accurately predict if such a disaster would occur before the device was even tested ... the calculations showed changes had to be made from the Linda's design for the Flute to perform correctly." - Dr Tom Ramos (Lawrence Livermore National Laboratory nuclear weapon designer), From Berkeley to Berlin: How the Rad Lab Helped Avert Nuclear War, Naval Institute press, 2022, pp153-4. Note that the piccolo (the W47 secondary) is a half-sized flute, so it appears that the W47's secondary stage design miniaturization history was: Linda -> Flute -> Piccolo:
"A Division's third challenge was a small thermonuclear warhead for Polaris [the nuclear SLBM submarine that preceeded today's Trident system]. The starting point was the Flute, that revolutionary secondary that had performed so well the previous year. Its successor was called the Piccolo. For Plumbbob [Nevada, 1957], the design team tested three variations of the Piccolo as a parameter test. One of the variants outperformed the others ... which set the stage for the Hardtack [Nevada and Pacific, 1958] tests. Three additional variations for the Piccolo ... were tested then, and again an optimum candidate was selected. ... Human intuition as well as computer calculations played crucial roles ... Finally, a revolutionary device was completed and tested ... the Navy now had a viable warhead for its Polaris missile. From the time Brown gave Haussmann the assignment to develop this secondary until the time they tested the device in the Pacific, only 90 days had passed. As a parallel to the Robin atomic device, this secondary for Polaris laid the foundation for modern thermonuclear weapons in the United States." - Dr Tom Ramos (Lawrence Livermore National Laboratory nuclear weapon designer), From Berkeley to Berlin: How the Rad Lab Helped Avert Nuclear War, Naval Institute press, 2022, pp177-8. (Ramos is very useful in explaining that many of the 1950s weapons with complex non-spherical, non-cylindrical shaped primaries and secondaries were simply far too complex to fully simulate on the really pathetic computers they had - Livermore got a 4,000 vacuum tubes-based IBM 701 with 2 kB memory in 1956, AWRE Aldermaston in the Uk had to wait another year for theirs - so they instead did huge numbers of experimental explosive tests. For instance, on p173, Ramos discloses that the Swan primary which developed into the 155mm tactical shell, "went through over 100 hydrotests", non-nuclear tests in which fissile material is replaced with U238 or other substitutes, and the implosion is filmed with flash x-ray camera systems.)
"An integral feature of the W47, from the very start of the program, was the use of an enriched uranium-235 pusher around the cylindrical secondary." - Chuck Hansen, Swords 2.0, p. VI-375 (Hansen's source is his own notes taken during a 19-21 February 1992 nuclear weapons history conference he attended; if you remember the context, "Nuclear Glasnost" became fashionable after the Cold War ended, enabling Hansen to acquire almost unredacted historical materials for a few years until nuclear proliferation became a concern in Iraq, Afghanistan, Iran and North Korea). The key test of the original (Robin primary and Piccolo secondary) Livermore W47 was 412 kt Hardtack-Redwood on 28 June 1958. Since Li6D utilized at 100% efficiency would yield 66 kt/kg, the W47 fusion efficiency was only about 6%; since 100% fission of u235 yields 17 kt/kg, the W47's Piccolo fission (the u235 pusher) efficiency was about 20%; the comparable figures for secondary stage fission and fusion fuel burn efficiencies in the heavy B28 are about 7% and 15%, respectively:
ABOVE: the heavy B28 gave a very "big bang for the buck": it was cheap in terms of expensive Pu, U235 and Li6, and this was the sort of deterrent which was wanted by General LeMay for the USAF, which wanted as many weapons as possible, within the context of Eisenhower's budgetary concerns. But its weight (not its physical size) made it unsuitable for SLBM Polaris warheads. The first SLBM warhead, the W47, was almost the same size as the B28 weapon package, but much lighter due to having a much thinner "pusher" on the secondary, and casing. But this came at a large financial cost in terms of the quantities of special nuclear materials required to get such a lightweight design to work, and also a large loss of total yield. The fusion fuel burn efficiency ranges from 6% for the 400 kt W47 to 15% for the 1.1 megaton B28 (note that for very heavy cased 11-15 megaton yield tests at Castle, up to 40% fusion fuel burn efficiency was achieved), whereas the secondary stage ablative pusher fission efficiency ranged from 7% for a 1.1 inch thick natural uranium (99.3% U238) ablator to 20% for a 0.15 inch thick highly enriched oralloy (U235) ablator. From the brief description of the design evolution given by Dr Tom Ramos (Lawrence Livermore National Laboratory), it appears that when the x-ray channelling outer case thickness of the weapon is reduced to save weight, the duration of the x-ray coupling is reduced, so the dense metal pusher thickness must be reduced if the same compression factor (approximately 20) for the secondary stage is to be accomplished (lithium deuteride, being of low density, is far more compressable by a given pressure, than dense metal). In both examples, the secondary stage is physically a boosted fission stage. (If you are wondering why the hell the designers don't simply use a hollow core U235 bomb like Orange Herald instead of bothering with such inefficient x-ray coupled two-stage designs as these, the answer is straightforward: the risk of large fissile core meltdown by neutrons Moscow ABM defensive nuclear warheads, neutron bombs.)
The overall weight of the W47 was minimized by replacing the usual thick layer of U238 pusher with a very thin layer of fissile U235 (supposedly Teller's suggestion), which is more efficient for fission, but is limited by critical mass issues. The W47 used a 95% enriched Li6D cylinder with a 3.8mm thick U235 pusher; the B28 secondary was 36% enriched Li6D, with a very heavy 3cm thick U238 pusher. As shown below, it appears the B28 was related to the Los Alamos clean design of the TX21C tested as 95% clean 4.5 megatons Redwing-Navajo in 1956 and did not have a central fissile spark plug. From the declassified fallout composition, it is known the Los Alamos designers replaced the outer U238 pusher of Castle secondaries with lead in Navajo. Livermore did the same for their 85% clean 3.53 megatons Redwing-Zuni test, but Livermore left the central fission spark plug, which contributed 10% of its 15% fission yield, instead of removing the neutron shield, using foam channel filler for slowing down the x-ray compression, and thereby using primary stage neutrons to split lithium-6 giving tritium prior to compression. Our point is that Los Alamos got it wrong in sticking too conservatively to ideology: for clean weapons they should have got rid of the dense lead pusher and gone for John H. Nuckolls idea (also used by Fuchs in 1946 and the Russians in 1955 and 1958) of a low-density pusher for isentropic compression of low-density fusion fuel. This error is the reason why those early cleaner weapons were extremely heavy due to unnecessary 2" thick lead or tungsten pushers around the fusion fuel, which massively reduced their yield-to-weight ratios, so that LeMay rejected them!
This is justified by the data given for a total U238 capture-to-fission ratio of 1 in the 11 megaton Romeo test and also the cross-sections for U235 capture and fission on the AWE graph for relevant neutron energy range of about 1-14 Mev. If half the neutrons are captured in U238 without fission, then the maximum fission yield you can possibly get from "x" kg of U238 pusher is HALF the energy obtained from 100% fission of "x" kg of U238. Since with U238 only about half the atoms can undergo fission by thermonuclear neutrons (because the other half undergo non-fission capture), the energy density (i.e., the Joules/kg produced by the fission explosion of the pusher) reached by an exploding U238 pusher is only half that reached by U235 (in which there is less non-fission capture of neutrons, which doubles the pusher mass without doubling the fission energy release). So a U235 pusher will reach twice the temperature of a U238 pusher, doubling its material heating of fusion fuel within, prolonging the fusion burn and thus increasing fusion burn efficiency. 10 MeV neutron energy is important since it allows for likely average scattering of 14.1 MeV D+T fusion neutrons and it is also the energy at which the most important capture reaction, the (n,2n) cross-section peaks for both U235 (peak of 0.88 barn at 10 Mev) and U238 (peak of 1.4 barns at 10 Mev). For 10 Mev neutrons, U235 and U238 have fission cross-sections of 1.8 and 1 barn, respectively. For 14 Mev neutrons, U238 has a (n,2n) cross section of 0.97 barn for U237 production. So ignoring non-fission captures, you need 1.8/1 = 1.8 times greater thickness of pusher for U238 than for U235, to achieve the same amount of fission. But this simple consideration ignores the x-ray ablation requirement of the explosing pusher, so there are several factors requiring detailed computer calculations, and/or nuclear testing.
Note: there is an extensive collection of declassified documents released after Chuck Hansen's final edition, Swords 2.0, which are now available at https://web.archive.org/web/*/http://www.nnsa.energy.gov/sites/default/files/nnsa/foiareadingroom/*, being an internet-archive back-up of a now-removed US Government Freedom of Information Act Reading Room. Unfortunately they were only identified by number sequence, not by report title or content, in that reeding room, and so failed to achieve wide attention when originally released! (This includes extensive "Family Committee" H-bomb documentation and many long-delayed FOIA requests submitted originally by Hansen, but not released in time for inclusion in Swords 2.0.) As the extract below - from declassified document RR00132 - shows, some declassified documents contained very detailed information or typewriter spaces that could only be filled by a single specific secret word (in this example, details of the W48 linear implosion tactical nuclear warhead, including the fact that it used PBX9404 plastic bonded explosive glued to the brittle beryllium neutron reflector around the plutonium core using Adiprene L100 adhesive!).
ABOVE: Declassified data on the radiation flow analysis for the 10 megaton Mike sausage: http://nnsa.energy.gov/sites/default/files/nnsa/foiareadingroom/RR00198.pdf
Note that the simplistic "no-go theorem" given in this extract, against any effect from varying the temperature to help the radiation channelling, was later proved false by John H. Nuckolls (like Teller's anti-compression "no-go theorem" was later proved false), since lowered temperature delivers energy where it is needed while massively reducing radiation losses (which go as the fourth power of temperature/x-ray energy in kev).

ABOVE secret reports on Australian-British nuclear test operations at Maralinga in 1956 and 1957, Buffalo and Antler, proved that even at 10 psi peak overpressure for the 15 kt Buffalo-1 shot, the dummy lying prone facing the blast was hardly moved due to the low cross-sectional area exposed to the blast winds, relative to standing dummies which were severely displaced and damaged. The value of trenches in protecting personnel against blast winds and radiation was also proved in tests (gamma radiation shielding of trenches had been proved at an earlier nuclear test in Australia, Operation Hurricane in 1952). (Antler report linked here; Buffalo report linked here.) This debunks the US Department of Defense models claiming that people will automatically be blown out of the upper floors of modern city buildings at very low pressures, and killed by the gravitational impact with the pavement below! In reality, tall buildings mutually shield one another from the blast winds, not to mention the radiation (proven in the latest post on this blog), and on seeing the flash most people will have time to lie down on typical surfaces like carpet which give a frictional resistance to displacement, ignored in fiddled models which assume surfaces have less friction than a skating rink; all of this was omitted from the American 1977 Glasstone and Dolan book "The Effects of Nuclear Weapons". As Tuck's paper below on the gamma radiation dose rate measurements on ships at Operation Crossroads, July 1946 nuclear tests proved, contrary to Glasstone and Dolan, scattered radiation contributions are small, so buildings or ships gun turrets provided excellent radiation "shadows" to protect personnel. This effect was then calculated by UK civil defence weapons effects expert Edward Leader-Williams in his paper presented at the UK's secret London Royal Society Symposium on the Physical Effects of Atomic Weapons, but the nuclear test data as always was excluded from the American Glasstone book published the next year, The Effects of Atomic Weapons in deference to lies about the effects in Hiroshima, including an "average" casualty curve which deliberately obfuscated huge differences in survival rates in different types of buildings and shelters, or simply in shadows!
Note: the DELFIC, SIMFIC and other computer predicted fallout area comparisons for the 110 kt Bikini Atoll Castle-Koon land surface burst nuclear test are false since the distance scale of Bikini Atoll is massively exaggerated on many maps, e.g. in the Secret January 1955 AFSWP "Fall-out Symposium", the Castle fallout report WT-915, and the fallout patterns compendium DASA-1251! The Western side of the Bikini Atoll reef is at 165.2 degrees East, while the most eastern island in the Bikini Atoll, Enyu, is at 165.567 degrees East: since there are 60 nautical miles per degree by definition, the width of Bikini Atoll is therefore (165.567-165.2)(60) = 22 nautical miles, approximately half the distance shown in the Castle-Koon fallout patterns. Since area is proportional to the square of the distance scale, this constitutes a serious exaggeration in fallout casualty calculations, before you get into the issue of the low energy (0.1-0.2 MeV) gamma rays from neutron induced Np239 and U237 in the fallout enhancing the protection factor of shelters (usually calculated assuming hard 1.17 and 1.33 MeV gamma rads from Co60), during the sheltering period of approximately 1-14 days after detonation.
"Since the nuclear stalemate became apparent, the Governments of East and West have adopted the policy which Mr Dulles calls 'brinkmanship'. This is a policy adopted from a sport ... called 'Chicken!' ... If one side is unwilling to risk global war, while the other side is willing to risk it, the side which is willing to run the risk will be victorious in all negotiations and will ultimately reduce the other side to complete impotence. 'Perhaps' - so the practical politician will argue - 'it might be ideally wise for the sane party to yield to the insane party in view of the dreadful nature of the alternative, but, whether wise or not, no proud nation will long acquiesce in such an ignominious role. We are, therefore, faced, quite inevitably, with the choice between brinkmanship and surrender." - Bertrand Russell, Common Sense and Nuclear Warfare, George Allen and Unwin, London, 1959, pp30-31.
Emphasis added. Note that Russell accepts lying about nuclear weapons just as gas weapons had been lied about in the 1920s-30s by "arms controllers" to start WWII, then he simply falls into the 1930s Cambridge Scientists Antiwar Group delusional propaganda fraud of assuming that any attempt to credibly deter fascism is immoral because it will automatically result in escalatory retaliation with Herman Goering's Luftwaffe drenching London with "overkill" by poison gas WMDs etc. In particular, he forgets that general disarmament pursued in the West until 1935 - when Baldwin suddenly announced that the Nazis had secretly produced a massive, unstoppable warmachine in two years - encouraged aggressors to first secretly rearm, then coerce and invade their neighbours while signing peace promises purely to buy more time for rearmament, until a world war resulted. Not exactly a great result for disarmament propaganda. So after obliterating what Reagan used to call (to the horror of commie "historians") the "true facts of history" from his mind, he advocates some compromise with the aggressors of the 30 September 1938 Munich Agreement peace-in-our-time sort, the historically proved sure fire way to really escalate a crisis into a major war by showing the green lamp to a loon to popular media acclaim and applause for a fairy tale utopian fantasy; just as the "principled" weak, rushed, imbecile withdrawl from Afghanistan in 2021 encouraged Putin to invade Ukraine in 2022, and also the green lamp for Hamas to invade Israel in 2023.
"... deterrence ... consists of threatening the enemy with thermonuclear retaliation should he act provocatively. ... If war is 'impossible', how can one threaten a possible aggressor with war? ... The danger, evoked by numerous critics, that such research will result in a sort of resigned expectation of the holocaust, seems a weak argument ... The classic theory of Clausewitz defines absolute victory in terms of disarmament of the enemy ... Today ... it will suffice to take away his means of retaliation to hold him at your mercy." - Raymond Aron, Introduction to Herman Kahn's 1962 Thinking About the Unthinkable, Weidenfield and Nicholson, London, pp. 9-12. (This is the commie support for arms control and disarmament has achieved, precisely the weakening of the West to take away credible deterrence.)
"75 years ago, white slavery was rampant in England. ... it could not be talked about openly in Victorian England, moral standards as to the subjects of discussion made it difficult to arouse the community to necessary action. ... Victorian standards, besides perpetuating the white slave trade, intensified the damage ... Social inhibitions which reinforce natural tendencies to avoid thinking about unpleasant subjects are hardly uncommon. ... But when our reluctance to consider danger brings danger nearer, repression has gone too far. In 1960, I published a book that attempted to direct attention to the possibility of a thermonuclear war ... people are willing to argue that it is immoral to think and even more immoral to write in detail about having to fight ... like those ancient kings who punished messengers who brought them bad news. That did not change the news; it simply slowed up its delivery. On occasion it meant that the kings were ill informed and, lacking truth, made serious errors in judgement and strategy. ... We cannot wish them away. Nor should we overestimate and assume the worst is inevitable. This leads only to defeatism, inadequate preparations (because they seem useless), and pressures toward either preventative war or undue accommodation." - Herman Kahn's 1962 Thinking About the Unthinkable, Weidenfield and Nicholson, London, pp. 17-19. (In the footnote on page 35, Kahn notes that original nuclear bullshitter, the 1950 creator of fake cobalt-60 doomsday bomb propaganda, Leo Szilard, was in the usual physics groupthink nutters club: "Szilard is probably being too respectful of his scientific colleagues who also seem to indulge in ad hominem arguments - especially when they are out of their technical specialty.")
"Ever since the catastropic and disillusioning experience of 1914-18, war has been unthinkable to most people in the West ... In December 1938, only 3 months after Munich, Lloyd's of London gave odds of 32 to 1 that there would be no war in 1939. On August 7, 1939, the London Daily Express reported the result of a poll of its European reporters. 10 out of 12 said, 'No war this year'. Hitler invaded Poland 3 weeks later." - Herman Kahn's 1962 Thinking About the Unthinkable, Weidenfield and Nicholson, London, p. 39. (But as the invasion of Ukraine in 2022 proved, even the label "war" is now "controversial": the aggressor now simply declares they are on a special operation of unifying people under one flag to ensure peace! So the reason why there is war in Ukraine is that Ukraine is resisting. If it waved a white flag, as the entire arms control and disarmament lobby insists is the only sane response to a nuclear-armed aggressor, there would be "peace," albeit on Russia's terms: that's why they disarmed Ukraine in 1994. "Peace propaganda" of "disarmers"! Free decent people prefer to fight tyranny. But as Kahn states on pp. 7-9:
"Some, most notably [CND's pseudo-historian of arms race lying] A. J. P. Taylor, have even said that Hitler was not like Hitler, that further appeasement [not an all-out arms race as was needed but repeatedly rejected by Baldwin and Chamberlain until far too late; see discussion of this fact which is still deliberately ignored or onfuscated by "historians" of the A. J. P. Taylor biased anti-deterrence left wing type, in Slessor's The Central Blue, quoted on this blog] would have prevented World War II ... If someone says to you, 'One of us has to be reasonable and it is not going to be me, so it has to be you', he has a very effective bargaining advantage, particularly if he is armed with thermonuclear bombs [and you have damn all civil defense, ABM, or credible tactical deterrent]. If he can convince you he is stark, staring mad and if he has enough destructive power ... deterrence alone will not work. You must then give in or accept the possibility of being annihilated ... in the first instance if we fight and lose; in the second if we capitulate without fighting. ... We could still resist by other means ranging from passive resistance of the Gandhi type to the use of underground fighting and sabotage. All of these alternatives might be of doubtful effectiveness against [the Gulag system, KGB/FSB torture camps or Siberian salt mines of] a ruthless dictatorship."
Sometimes people complain that Hitler and the most destructive and costly war and only nuclear war of history, WWII, is given undue attention. But WWII is a good analogy to the danger precisely because of the lying WMD gas war propaganda-based disarmament of the West which allowed the war, because of the attacks by Hitler's fans on civil defense in the West to make even the token rearmament after 1935 ineffective as a credible deterrent, and because Hitler has mirrors in Alexander the Great, Attila the Hun, Ghengis Khan, Tamerlane, Napoleon and Stalin. Kahn explains on p. 173: "Because history has a way of being more imaginative and complex than even the most imaginative and intelligent analysts, historical examples often provide better scenarios than artificial ones, even though they may be no more directly applicable to current equipment, postures, and political situations than the fictional plot of the scenario. Recent history can be especially useful.")
"One type of war resulting at least partly from deliberate calculation could occur in the process of escalation. For example, suppose the Soviets attacked Europe, relying upon our fear of their reprisal to deter a strategic attack by us; we might be deterred enough to pause, but we might evacuate our cities during this pause in the hope we could thereby convince the Soviets we meant business. If the Soviets did not back down, but continued their attack upon Europe, we might decide that we would be less badly off if we proceeded ... The damage we would receive in return would then be considerably reduced, compared with what we would have suffered had we not evacuated. We might well decide at such a time that we would be better off to attack the Soviets and accept a retalitory blow at our dispersed population, rather than let Europe be occupied, and so be forced to accept the penalty of living in the hostile and dangerous world that would follow." - Herman Kahn's 1962 Thinking About the Unthinkable, Weidenfield and Nicholson, London, pp. 51-2.
"We must recognise that the stability we want in a system is more than just stability against accidental war or even against an attack by the enemy. We also want stability against extreme provocation [e.g. invasion of allies, which then escalates as per invasion of Belgium 1914, or Poland 1939]." - Herman Kahn's 1962 Thinking About the Unthinkable, Weidenfield and Nicholson, London, p. 53(footnote).
Note: this 1962 book should not be confused with Kahn's 1984 "updated" Thinking About the Unthinkable in the 1980s, which omits the best material in the 1962 edition (in the same way that the 1977 edition of The Effects of Nuclear Weapons omits the entire civil defense chapter which was the one decent thing in the 1957 and 1962/4 editions!) and thus shows a reversion to the less readable and less helpful style of his 1960 On Thermonuclear War, which severely fragmented and jumbled up all the key arguments making it easy for critics to misquote or quote out of context. For example, Kahn's 1984 "updated" book starts on the first page of the first chapter with the correct assertion that Johnathan Schell's Fate of the Earth is nonsense, but doesn't say why it's nonsense, and you have to read through to the final chapter - pages 207-8 of chapter 10 - to find Kahn writing in the most vague way possible, without a single specific example, that Schell is wrong because of "substantive inadequacies and inaccuracies", without listing a single example such as Schell's lying that the 1954 Bravo nuclear test blinded everyone well beyond the range of Rongelap, and that it was impossible to easily shield the radiation from the fallout or evacuate the area until it decays, which Schell falsely attributed to Glasstone and Dolan's nonsense in the 1977 Effects of Nuclear Weapons! Kahn eventually in the footnote on page 208 refers readers to an out-of-print article for facts: "These criticisms are elaborated in my review of The Fate of the Earth, see 'Refusing to Think About the Unthinkable', Fortune, June 28, 1982, pp. 113-6. Kahn does the same for civil defense in the 1984 book, referring in such general, imprecise and vague terms to Russian civil defence, with no specific data, that it is a waste of time, apart possibly one half-baked sentence on page 177: "Variations in the total megatonnage, somewhat surprisingly, do not seem to affect the toll nearly as much as variations in the targetting or the type of weapon bursts." Kahn on page 71 quotes an exchange between himself and Senator Proxmire during the US Congressional Hearings of the Joint Committee on Defense Production, Civil preparedness and limited nuclear war where on page 55 of the hearings, Senator Proxmire alleges America would escalate a limited conflict to an all-out war because: "The strategic value and military value of destroying cities in the Soviet Union would be very great." Kahn responded: "No American President is likely to do that, no matter what the provocation." Nuclear war will be limited, according to Herman Kahn's analysis, despite the bullshit fron nutters to the contrary.
Kahn on page 101 of Thinking About the Unthinkable in the 1980s correctly and accurately condemns President Carter's 1979 State of the Union Address, which claimed falsely that just a single American nuclear submarine is required by America and has an "overwhelming" deterrent against "every large and medium-sized city in the Soviet Union". Carter ignored Russian retaliation on cities if you bomb theirs: America has avoided the intense Russian protection efforts that make the Russian nuclear threat credible, namely civil defense shelters and evacuation plans, and also the realpolitik of deterrence of world wars, which so far have only been triggered due to invasions of third parties (Belgium '14, Poland '39). Did America strategically nuke every city in Russia when it invaded Ukraine in 2022? No, debunking Proxmire and the entire Western pro-Russian "automatic escalation" propaganda lobby, and it didn't even have tactical neutron bombs to help deter the Russians like Reagan in the 1980s, because in the 1990s America had ignored Kahn's argument, and went in for MINIMAL deterrence of the least credible sort (abolishing the invasion-deterring dedicated neutron tactical nuclear stockpile entirely; the following quotation is from p101 of Kahn's Thinking About the Unthinkable in the 1980s):
"Minimum deterrence, or any predicated on an escessive emphasis on the inevitably of mutual homocide, is both misleading and dangerous. ... MAD principles can promote provocation - e.g. Munich-type blackmail on an ally. Hitler, for example, did not threaten to attack France or England - only Austria, Czechoslovakia, and Poland. It was the French and the British who finally had to threaten all-out war [they could only do this after rearmament and building shelters and gas masks to reduce the risk of reprisals in city bombing, which gave more time for Germany to prepare since it was rearming faster than France and Britain which still desperately counted on appeasement and peace treaties and feared provoking a war by an arms-race due to endless lying propaganda from Lord Grey that his failure to deter war in 1914 had been due to an arms-race rather than the incompetence of the procrastination of his anti-war Liberal Party colleagues in the Cabinet] - a move they would not and could not have made if the notion of a balance of terror between themselves and Germany had been completely accepted. As it was, the British and French were most reluctant to go to war; from 1933 to 1939 Hitler exploited that reluctance. Both nations [France and Britain] were terrified by the so-called 'knockout blow', a German maneuver that would blanket their capitals with poison gas ... The paralyzing effect of this fear prevented them from going to war ... and gave the Germans the freedom to march into the Ruhr, to form the Anschluss with Austria, to force the humiliating Munich appeasement (with the justification of 'peace in our time'), and to take other aggressive actions [e.g. against the Jews in the Nuremberg Laws, Kristallnacht, etc.] ... If the USSR were sufficiently prepared in the event a war did occur, only the capitalists would be destroyed. The Soviets would survive ... that would more than justify whatever sacrifice and destruction had taken place.
"This view seems to prevail in the Soviet military and the Politburo even to the present day. It is almost certain, despite several public denials, that Soviet military preparations are based on war-fighting, rather than on deterrence-only concepts and doctrines..." - Herman Kahn, Thinking About the Unthinkable in the 1980s, 1984, pages 101-102.
Kahn adds, in his footnote on p111, that "Richard Betts has documented numerous historical cases in which attackers weakened their opponents defenses through the employment of unanticipated tactics. These include: rapid changes in tactics per se, false alarms and fluctuating preparations for war ... doctrinal innovations to gain surprise. ... This is exactly the kind of thing which is likely to surprise those who subscribe to MAD theories. Those who see a need for war-fighting capabilities expect the other side to try to be creative and use tactical innovations such as coercion and blackmail, technological surprises, or clever tactics on 'leverage' targets, such as command and control installations. If he is to adhere to a total reliance on MAD, the MADvocate has to ignore these possibilities." See Richard Betts, "Surprise Despite Warning: Why Sudden Attacks Succeed", Political Science Quarterly, Winter 1980-81, pp. 551-572.)
Compare two situations: (1) Putin explodes a 50 megaton nuclear "test" of the warhead for his new nuclear reactor powered torpedo, Poseidon, a revamped 1961 Tsar Bomba, or detonates a high-altitude nuclear EMP "test" over neutral waters but within the thousands of miles range of USA or UK territory; (2) Putin invades Poland using purely conventional weapons. Our point here is that both nuclear AND conventional weapons trigger nuclear threats and the risk of nuclear escalation, as indeed they have done (for Putin's nuclear threats scroll down to videos with translations below). So the fashionable CND style concept that only nuclear weapons can trigger nuclear escalation is bullshit, and is designed to help Russia start and win WWIII to produce a world government, by getting us to undertake further unilateral (not multilateral) disarmament, just as evolved in the 1930s, setting the scene for WWII. Japan for example did not have nuclear weapons in August 1945, yet triggered not just tactical nuclear war (both cities had some military bases and munitions factories, as well as enormous numbers of civilians), and the decision to attack cities rather than just "test" weapons obove Tokyo bay as Teller demanded but Oppenheimer rejected (for maximum impact with a very small supply of nuclear weapons) showed some strategic nuclear war thinking. Truman was escalating to try to shock Japan into rapid surrender emotionally (many cities in Japan had already been burned out in conventional incendiary air raids, and the two nuclear attacks while horrible for civilians in those cities contributed only a fraction of the millions killed in WWII, despite anti-nuclear propaganda lies to the contrary). Truman's approach escalating to win is the opposite of the "Minimax game theory" (von Neumann's maths and Thomas Schelling's propaganda) gradual escalation approach that's currently the basis of nuclear deterrence planning despite its failure wherever it has been tried (Vietnam, Afghanistan, etc). Gradual escalation is supposed to minimise the maximum possible risk (hence "minimax" name), but it guarantees failure in the real world (unlike rule abided games) by maximising the build up of resentment. E.g. Schelling/Minimax say that if you gradually napalm civilians day after day (because they are the unprotected human shields used by terrorists/insurgents; the Vietcong are hiding in underground tunnels, exactly like Hamas today, and the Putin regime's metro 2 shelter tunnels under Russia) you somehow "punish the enemy" (although they don't give a toss about the lives of kids which is why you're fighting them!) and force them to negotiate for peace in good faith, then you can pose for photos with them sharing a glass of champagne and there is "world peace". That's a popular fairy tale, like Marxist mythology.
Once you grasp this fact, that nuclear weapons have been and will again be "used" explosively without automatic escalation, for example provocative testing as per the 1961 Russian 50 megaton bomb test, or the 1962 high altitude EMP bursts, you should be able to grasp the fact that the "escalation" deception used to dismiss civil defense and tactical nuclear deterrence against limited nuclear war, is fake news from Russian fellow-travellers like Corbyn. Once you assign a non-unity probability to "escalation", you're into conventional war territory: if you fight a conventional war, it can "escalate" to nuclear war as on 6 August 1945. Japan did not avoid nuclear attack by not having nuclear weapons on 6 August 1945. If it had nuclear weapons ready to be delivered, a very persuasive argument could be made that unless Truman wanted to invite retaliation, World War II would have remained strategically non-nuclear: no net strategic advantage would have been achieved by nuclear city bombing so only war-ending tactical nuclear threats could have prevailed in practice. But try explaining this to the groupthink pseudosocialist bigoted mass murderers who permeate fake physics with crap; it's no easier to explain to them the origins of particle masses or even dark energy/gravitation; in both cases groupthink lying hogwash persists because statements of proved facts are hated and rejected if them debunk religious style fairy tales the mass media loves. There were plenty of people warning that mass media gas war fear mongering was disguised Nazi supporting propaganda in the 1930s, but the public listened to that crap then just as it accepted the "eugenics" (anti-diversity evolution crap of Sir Galton, cousin of Darwin) basis for Hitler's Mein Kampf without question, just as they accepted the lying propaganda from the UK "Cambridge Scientists Anti-War Group" which like CND and all other arms control and disarmament lobbies supporting terrorist states today, did more than even Hitler to deliberately lay the foundations for the Holocaust and World War II, while never being criticised in the UK media! Thus, it's surely time for people to oppose evil lying on civil defence to save lives in all disasters from storms to conventional war, to collateral damage risks in nuclear terrorism by mad enemies. At some point, the majority has to decide to either defend itself honestly and decently against barbarism, or be consumed by it as a price for believing bullshit. It's time for decent people to oppose lying evil regarding the necessity to have credible tactical (not incredible strategic) nuclear weapons, as Oppenheimer called for in his 1951 speech, to deter invasions.
Democracy can't function when secrecy is used to deliberately cover-up vital data from viewing by Joe Public. Secrecy doesn't protect you from enemies who independently develop weapons in secret, or who spy from inside your laboratories:
"The United States and Great Britain resumed testing in 1962, and we spared no effort trying to find out what they were up to. I attended several meetings on that subject. An episode related to those meetings comes to mind ... Once we were shown photographs of some documents ... the photographer had been rushed. Mixed in with the photocopies was a single, terribly crumpled original. I innocently asked why, and was told that it had been concealed in panties. Another time ... questions were asked along the following lines: What data about American weapons would be most useful for your work and for planning military technology in general?"
- Andrei Sakharov, Memoirs, Hutchinson, London, 1990, pp225-6.
Nuclear saber-rattling from Russian propagandists. They think tactical nuclear weapons aren't enough, and strategic ones should be used.

More news of Russian TV population preparation for nuclear escalations, which the Western media and politicians continue to ignore as propaganda, just as Novichok and the Ukraine invasion prep was ignored as propaganda bluff, until it took us by "surprise".

ABOVE: The British government has now declassified detailed summary reports giving secret original nuclear test data on the EMP (electromagnetic pulse) damage due to numerous nuclear weapons, data which is still being kept under wraps in America since it hasn't been superseded because Western atmospheric nuclear tests were stopped late in 1962 and never resumed - even though the Russians have even more extensive data - completely debunking Glasstone and Dolan's disarmament propaganda nonsense in the 1962, 1964 and 1977 Effects of Nuclear Weapons which ignores EMP piped far away from low altitude nuclear tests by power and communications cables and falsely claims instead that such detonations don't produce EMP damage outside the 2psi blast radius! For a discussion of the new data and also a link to the full 200+ pages version (in addition to useful data, inevitably like all official reports it also contains a lot of "fluff" padding), please see the other (physics) site: https://nige.wordpress.com/2023/09/12/secret-emp-effects-of-american-nuclear-tests-finally-declassified-by-the-uk-and-at-uk-national-archives/ (by contrast, this "blogspot" uses old non-smartphone proof coding, no longer properly indexed any long longer by "google's smartphone bot"). As long ago as 1984, Herman Kahn argued on page 112 of his book Thinking About the Unthinkable in the 1980s: "The effects of an EMP attack are simply not well understood [in the West, where long powerlines were never exposed on high altitude nuclear tests, unlike the Russian's 1962 Operation K, so MHD-EMP or E3 damage wasn't even mentioned in the 1977 Glasstone and Dolan Effects of Nuclear Weapons], but the Soviets seem to know - or think they know - more than we do."
ABOVE: Moscow Metro and Metro-2 (secret nuclear subway) horizonially swinging blast doors take only 70 seconds to shut, whereas their vertically rising blast doors take 160 seconds to shut; both times are however far shorter than the arrival time of Western ICBMs or even SLBMs which take 15-30 minutes by which time the Russian shelters are sealed from blast and radiation! In times of nuclear crisis, Russia planned to evacuate from cities those who could not be sheltered, and for the remainder to be based in shelters (similarly to the WWII British situation, when people slept in shelters of one kind or another when there was a large risk of being bombed without notice, particularly in supersonic V2 missile attacks where little warning time was available).
NUKEGATE - Western tactical neutron bombs were disarmed after Russian propaganda lie. Russia now has over 2000... "Disarmament and arms control" charlatans, quacks, cranks, liars, mass murdering Russian affiliates, and evil genocidal Marxist media exposed for what it is, what it was in the 1930s when it enabled Hitler to murder tens of millions in war. Glasstone's and Dolan's 1977 Effects of Nuclear Weapons deceptions totally disproved. Professor Brian Martin, TRUTH TACTICS, 2021 (pp45-50): "In trying to learn from scientific publications, trust remains crucial. The role of trust is epitomised by Glasstone’s book The Effects of Atomic Weapons. Glasstone was not the author; he was the editor. The book is a compilation of information based on the work of numerous contributors. For me, the question was, should I trust this information? Was there some reason why the editors or authors would present fraudulent information, be subject to conflicts of interest or otherwise be biased? ... if anything, the authors would presumably want to overestimate rather than underestimate the dangers ... Of special interest would be anyone who disagreed with the data, calculations or findings in Glasstone. But I couldn’t find any criticisms. The Effects of Nuclear Weapons was treated as the definitive source, and other treatments were compatible with it. ... One potent influence is called confirmation bias, which is the tendency to look for information that supports current beliefs and dismiss or counter contrary information. The implication is that changing one’s views can be difficult due to mental commitments. To this can be added various forms of bias, interpersonal influences such as wanting to maintain relationships, overconfidence in one’s knowledge, desires to appear smart, not wanting to admit being mistaken, and career impacts of having particular beliefs. It is difficult to assess the role of these influences on yourself. "
Above: the target for Sam Cohen's neutron bomb was these T-54/55 Russian main battle tanks, which had the highest production run of any tank ever made (over 86,000 were manufactured). They were manufactured chiefly for the invasion of Western Europe, once tactical nuclear weapons had been removed by political lobbying of Western disarmament activists via the Kremlin-controlled World Peace Council based in Moscow.
Above: Lying CND propaganda postcard on the neutron bomb issued by Yorkshire Region CND (campaign for nuclear disarmament). The back of the postcard falsely claims: 'Civilians, rather than easily protected tanks, will be the main targets.' You can't easily protect a tank from hundreds of thousands of rads of extremely high energy (14.1 MeV) fusion neutrons, which is the whole point of the neutron bomb. The well-known good absorbers for low energy neutrons in a nuclear reactor (cadmium and boron) are relatively ineffective at capturing such high energy neutrons, and if you use heavy metals to scatter and slow down the high energy neutrons, like steel or depleted uranium, you get gamma rays given off when the neutrons deposit energy in the nuclei they strike. So then you have a secondary radiation hazard, not to mention the immense weight increase to the tank which would have major implications (tanks are normally extremely heavy and a massive increase in armour would have severely detrimental effects, such as bogging them down more easily, increasing fuel consumption and decreasing speed). If civilians (not in tanks) were the targets, you wouldn't need to use short-range radiation effects because you could just use blast and fallout against them, but they weren't the targets. As the lying CND propagandarists knew, the deterrent targets were the Warsaw Pact communist tanks which outnumbered those on the West by three-to-one:
Above: Samuel Cohen's calculation of the gamma dose rate from deposited fallout formed Appendix D of Glasstone's 1950 Effects of Atomic Weapons. Cohen also contributed the analysis of dose rates to aircraft flying inside the mushroom cloud at various times after detonation. In his fallout calculations (Appendix D), Cohen ignored air scattered gamma ray contributions and just summed the direct gamma ray contributions from a smooth plane. It turned out that this approximation gave results which are accurate for typical rough ground if scattered gamma rays are included. For a smooth, infinite, uniformly contaminated surface including the contribution from air scattered gamma rays, 50% of the dose rate at 1 metre height comes from fallout within a 15 metres radius; for Cohen's approximation (ignoring air scatter) this radius is only 8 metres which is about the same as for rough terrain (where the terrain absorbs some of the radiation, particularly from great distances) where air scatter is included.
While he did not discuss Dr Samuel T. Cohen’s neutron bomb in The Effects of Nuclear Weapons, Glasstone in an article called 'Nuclear Weapons' for Microsoft's Encarta 97 critically argued that 95 % clean neutron bombs are the way forward, to totally avoid collateral damage in nuclear war (published by Microsoft Corporation in the Microsoft Encarta 97 Encyclopaedia CD-ROM, 1997):
‘If an H-bomb were made with no uranium jacket but with a fission trigger ... as little as 5 percent of the total explosive force might result from fission; the weapon would thus be 95 percent clean. The enhanced radiation fusion bomb, also called the neutron bomb, which has been tested by the United States and other nuclear powers ... is considered a tactical weapon because it can do serious damage on the battlefield [assuming a 1-kt air burst at 500 m altitude], penetrating tanks and other armoured vehicles and causing death or serious injury to exposed individuals, without producing the radioactive fallout that endangers people or structures miles away.’
'When I arrived at the [Los Alamos] Lab 36+ years ago ... though I was a lowly postdoc, we took a course on nuclear physics (as did every new employee) and then a class on elements of bomb design both taught by Samuel Glasstone. This was required training. ... After that approximately 3 weeks of training, I understand what the Lab was about and why it was important to the nation. I'm certain it contributed to my wanting to stay on after my postdoc and has helped me in my work over the years. This was part of the "openness" despite the secrecy associated with the Lab. I believe we have lost this over the years ...' - Dr David Forslund
Above (click on images to enlarge): the neutron bomb is included under the title 'enhanced neutron weapon' in Philip J. Dolan's originally secret manual Capabilities of Nuclear Weapons, DNA-EM-1, U.S. Department of Defense, Chapter 5, Nuclear Radiation Phenomena, August 1981 revision. According to the Medical NBC Battlebook, USACHPPM Tech Guide 244, May 2000, page 2-18, a 3 kt enhanced neutron weapon with a fission yield of 50% (i.e. 5% of yield as residual radiation, which is a trivial effect for the burst height of the neutron bomb) will release 30% of its energy as blast (trivial for the 720 metres height of burst for tactical use of a 3 kt neutron bomb), 20% as thermal radiation (again, relatively trivial even near ground zero, due to yield and burst altitude), and 45% as inital nuclear radiation. These ratios will be altered for other fission yields. At very low yields, there is a problem with using a small fission primary to ignite the fusion stage in a Teller-Ulam device because the fraction of yield released as X-rays by a very low yield fission device is small (it depends strongly on the yield to mass ratio of the primary stage), thus the fusion stage ignition-efficiency due to X-ray ablation induced recoil falls. Most of the energy from a low yield primary stage is in a relatively slow moving (compared to light-velocity X-rays) debris hydrodynamic shock wave, that delivers energy to the fusion stage slowly and without efficient focussing. Fortunately, the neutron bomb is not concerned with maximising Teller-Ulam efficiency, but with producing a small yield with a maximised neutron output!
The basic mechanism of the neutron bomb was discovered by Samuel Cohen of RAND Corporation in 1958 when studying the neutron outputs from two Lawrence Livermore National Laboratory clean (low fission) bomb designs (Dove and Starling) of low yield devices for peaceful explosive uses like excavating harbours, canals, and mountain passes, and is simply that the case thickness needed by a Teller-Ulam device to channel X-rays from primary to secondary scaled as the cube root of the total yield. Hence the casing required is 10 times thicker for 1 Mt than for 1 kt, so in a 1 kt Teller-Ulam device, most of the neutrons can escape from the thin casing, while in a 1 Mt Teller-Ulam device the neutrons are mostly absorbed because of the much thicker casing required. Thus neutron bombs have a yield range of 1-10 kilotons, with fission yield varying from 50% at 1-kiloton to 25% at 10-kilotons (all of which comes from the primary stage). The neutron output per kiloton is 10-15 times greater than for a pure fission implosion weapon.Above: neutron attenuation in air according to energy, in Philip J. Dolan's originally secret manual Capabilities of Nuclear Weapons, DNA-EM-1, U.S. Department of Defense, Chapter 5, Nuclear Radiation Phenomena, August 1981 revision (the simple geometric inverse square law of divergence of neutrons from a point source isn't included in the shielding curves above). Notice that over small distances in the air, the neutron fluence is higher than in a vacuum, because there is little attenuation by air over a short distance, but you get an additional large neutron dose from neutrons being scattered back at you which have gone past (and also through) you, and have then been scattered back at you, by large number of nuclei which are obviously located at greater distances (beyond your distance from the detonation!). This is also why tanks can't be protected with a relatively light weight shield on top of the crew compartment, as we shall see later on: it is not possible to protect tanks existing against neutron radiation without adding so much mass the turret would be retarded and the performance of the tank would be crippled. A tank designed to properly protect its crew against 14.1 MeV neutron bomb neutrons and with a big enough engine to perform reasonably well, would be so heavy it would be swallowed up by the earth and simply disappear into soft ground, being rendered useless (the shielding of 14.1 MeV neutrons has nothing to do - either in mechanism or in amount of shielding - with the easy-to-shield thermalized 0.025 eV neutrons by cadmium control rods in a nuclear reactor). Above: neutron bomb doses compared to other weapons, in Philip J. Dolan's originally secret manual Capabilities of Nuclear Weapons, DNA-EM-1, U.S. Department of Defense, Chapter 5, Nuclear Radiation Phenomena, August 1981 revision.
The enhanced neutron weapon or ‘neutron bomb’ is just a relatively clean very low yield two stage Teller-Ulam device; the low total yield means that only a very thin steel casing is required to reflect X-rays from the fission primary on to the fusion secondary stage. The thin casing of such a weapon ensures that most of the 17.6 MeV fusion energy from deuterium and tritium fusion into helium-4 escapes as neutrons: 80% of the energy is carried by neutrons, and 20% is carried by the helium-4 nucleus or alpha particle. This suppresses the amount of energy available for producing the blast and thermal radiation effects.
The primary strategic uses of clean, low fission yield enhanced neutron warheads are:
(1) to avert EMP collateral damage (due to low fission yield and low total yield) for ABM missiles by using the neutron output to melt and destroy plutonium cores in incoming ICBMs (neutrons have a long range in space);
(2) to deter massed tank attacks in cities or close to friendly forces. The deterrent here is the fact that neutron irradiated tank crews would be disabled within minutes and dead within hours to days; and
(3) to deter warship assaults by the threat of putting them out of action without nearby collateral damage or fallout.
Steel armour is resistant to blast and heat, but provides little shielding against fast fusion neutrons. The well-known neutron absorbers used in nuclear reactor control rods are little use against neutron bomb radiation, because they are good absorbers of 0.025 eV ‘thermalized’ neutrons in a nuclear reactor with a moderator, but useless against the 14.1 MeV neutrons from neutron bomb fusion, which have 560 million times more energy than thermal neutrons. Heavier armor, like that of the M-1 tank, employs depleted uranium which (although it is not significantly fissioned by low-energy thermal neutrons) actually increases the effectiveness of neutron radiation because it undergoes fission when hit by the 14.1 MeV high energy neutrons from neutron bomb, generating additional neutrons and becoming radioactive.
Because the blast and heat are suppressed in the neutron bomb, they have a similar damaging range to the lethal neutron radiation, so there is no collateral damage outside the target area. In some cases, a few broken windows can occur at greater distances, but there is no risk of dangerous blast-wind accelerated glass fragments, because the blast winds are trivial outside the neutron irradiate area.
Provided that the weapon was not used in a thunderstorm, no fallout effects would occur from the use of a neutron bomb, as the combination of 500 m burst altitude and low yield prevents fallout in addition to significant thermal and blast effects. The reduction in damage outside the target area is a major advantage of such a weapon to deter massed tank invasions. An aggressor would thus be forced to disperse tanks, which would make them easier to destroy by simple hand-held anti-tank missile launchers.
In 1979, Samuel Cohen was in Paris helping the French build neutron bombs, when presidential candidate Ronald Reagan came through on a European tour. Cohen met with Reagan to brief him on the neutron bomb. Reagan grasped the idea of neutron weaponry immediately, and made a pledge to Cohen that he would reverse Carter administration policy by building and deploying neutron bombs.
'The first time I recall seeing the term "neutron bomb" was in U.S. News and World Report. This was in May 1959, when the magazine revealed that the U.S. was working on a "neutron 'death ray' bomb which would kill man with streams of poisonous radiation, while leaving machines and buildings undamaged.'
Cohen adds in a footnote on that page that the neutron bomb: 'never did catch on at RAND, which was far more of a campus department than an objective think tank. ... However, I did find out that a good-looking blonde down the hall had expressed interest in hearing my briefing. ... some months later I married her.' On page 61 he explains: 'From the very beginning of the neutron bomb saga there has been one thing that particularly impressed - better yet, depressed - me about renowned American scientists. This is their ability to be impeccably careful and responsible when working in their fields of specilization (if they're not, their colleagues will catch them and even punish them) but their sloppiness and irresponsibility when giving their scientific opinion on nuclear weapons when they have an ideological bias against them, because they know that their colleagues, who share their bias, don't give a damn when they do this.'
Above: Cohen's comparison of the destruction he saw first-hand in Korea from conventional war (1950-3), with the nuclear destruction in Hiroshima. The only difference is that Hiroshima had mainly wooden houses which were burned down, whereas Seoul had more brick and concrete buildings. The Hiroshima photo was taken on 12 October 1945 (U.S. Army Photo #SC 290666); the Seoul photo was taken on 1 November 1950 (U.S. Army Photo #SC 352260).
In 1961, Cohen briefed President Kennedy's national security advisor McGeorge Bundy on the neutron bomb (The Truth About the Neutron Bomb, 1983, pp. 72-3): 'His response was that if we had to use nuclear weapons to stop the Red Army from taking over Europe, he would favor hitting them with the biggest weapons we had. My riposte was: "On our allies' soil?" He didn't reply. ... He had gotten the point. That ended the meeting.' Consequently, President John F. Kennedy authorized the 1963 testing of the neutron bomb underground by Livermore scientists in the Nevada, which 'worked out extremely well' (page 83).
Soviet Premier Nikita Khrushchev fanatically denounced the discriminate neutron bomb in his speech to the Romanian Party Congress in Bucharest: 'More and more frequently now, we hear from statesmen and military leaders, particularly in the United States, that they are working toward the creation of a neutron bomb. ... They are acting on the principle of robbers wanting to kill a man in such a way that his suit will not be stained with blood, in order to appropriate the suit. ... the bestial ethics of the most aggressive representatives of imperialism. ... Man to them is nothing. For them the main thing is to plunder, a quest for profit which prods the imperialists to the most horrible crimes.'
Cohen prints a Dunagin's people satire from 1977, showing a politician ordering physicists to modify the neutron bomb to fit Khrushchev's alleged morality:
'There are strong moral objections to a bomb that kills but doesn't destroy buildings. Fix it so it destroys buildings, too.'
On pages 91-2, Cohen explains: 'A discriminate tactical nuclear weapon is one whose effects can be confined mainly to the military target, minimizing damage to non-combatants and their property. So neutron bombs, which are intended to kill enemy soldiers but spare civilians and their towns, are, by this definition, discriminate weapons. For example, had they been available in the Korean War [which Cohen saw first hand] for use against enemy soldiers fighting in the city of Seoul, their application would have represented a highly discriminate attack - far more so than was the attack that actually took place using conventional weapons, and which pretty well levelled the city.'
He was inspired to invent and promote the neutron bomb by the vast civilian casualties from collateral damage due to the conventional weapons he saw in Korea, and by the NATO 'Carte Blanche' exercise of 23-28 June 1955, which predicted that the 268 nuclear explosions over 3 days in Germany which would be needed to defend Western Europe from Warsaw Pact forces would kill 1,500,000 civilians, and injure a further 3,500,000. By using neutron bomb air bursts (500-1,000 m altitude for 1-10 kt yields), all of these civilian casualties could be avoided. There would be no significant fallout, and the small area of neutron induced activity at ground zero decays very rapidly, as in Hiroshima and Nagasaki. The uselessness of conventional defences to stop massed tank invasions was clearly demonstrated by the French anti-tank Maginot Line, which failed in World War II when Nazi tanks bypassed it and went through the Ardennes Forest to invade France.
On 12 July 1977, President Jimmy Carter publically announced the development of a neutron bomb to deter massed Soviet tank invasions of Western Europe because the Warsaw Pact had 25,000 tanks in Eastern Europe, ready for an invasion. Cohen on page 109 points out that President Reagan in 1981 stated that the Soviet Union responded by pumping over $100,000,000 into an anti-neutron bomb 'peace' propaganda campaign. Premier Leonid Brezhnev offered to refrain from building the neutron bomb if America agreed to do likewise! President Carter responded (Cohen, p. 111):
'The Soviets know and President Brezhnev knows that the neutron weapon is designed to be used against massive and perhaps overwhelming tank forces. ... The neutron weapons are designed to equalize that inequality. ... The Soviets have no use for a neutron weapon, so the offer by Brezhnev to refrain from building the neutron weapon has no significance in the European theatre and he knows this.'
But Carter chickened out when the Soviet anti-neutron bomb propaganda assault on the media commenced. Moscow radio was followed by 28 different European communist parties statements denouncing the neutron bomb as an immoral weapon, and the Soviet funded 'World Peace Council' (similar to Hitler's '25-year-peace plan' propaganda spin before World War II) called a week of international anti-neutron bomb action in August 1977, lying that the neutron bomb was designed to kill civilians and leave cities intact for American invasions and plunder. The pro-communist left-wing media of the West, plus the anti-nuclear biased groups, lapped it all up. Grigori Gokshin, Secretary of the 'Soviet Peace Committee' from 1973-91, conducted war on the neutron bomb through the media to protect the Soviet tank advantage in Europe!
Carter continued to postpone his decision on the neutron bomb. Undeterred, the Soviet Union in 1979 invaded Afghanistan with tanks in what many considered a forerunner to an invasion of Western Europe and the rest of the free world. President Ronald Reagan was elected, and he ordered the production of 700 neutron bombs (350 nuclear 20-cm diameter shells for howitzers, and 350 W70 warheads for tactical Lance missiles) on 8 August 1981 to help to deter an invasion from the 19,500 Warsaw Pact tanks. Responding on 8 March 1983 to the Soviet 'peace morality' propaganda, Reagan pleaded: 'I urge you to beware the temptation to label both sides "equally at fault", to ignore the facts of history and the aggressive impulses of an evil empire, to simply call the arms race a "giant misunderstanding", and thereby remove yourself from the struggle between right and wrong, and good and evil.'
The neutron bomb is efficient against massed tank invasions, thus an aggressor would be forced to disperse tanks; making them easy for troops to destroy or halt individually using simple hand-launched anti-tank rockets.
Dr Edward Teller and Dr Albert L. Latter were the first to suggest this solution on page 171 of their book Our Nuclear Future: Facts, Dangers and Opportunities, Criterion Books, New York, 1958:
'In a nuclear war it will not make sense to use massed manpower. Any such concentration will provide too good a target for atomic weapons. ...
'Any fighting unit in a nuclear war will have to be small, mobile, inconspicuous and capable of independent action. ...
'If an invader adopts extreme dispersion, it will become impossible to defeat him with atomic weapons. But a very highly dispersed army can be defeated by a determined local population [with hand-held anti-tank rockets, etc.]. Therefore the main role of nuclear weapons might well be to disperse any striking force so that the resistance of people defending their homes can become decisive. Nuclear weapons may well become the answer to massed armies and may put back the power into the hands where we believe it belongs: the hands of the people.'
This is simple physics, but chemist George Kistiakowsky falsely claimed in MIT's Technology Review that 'A 10-cm (about 4 inches) layer of a suitable hydrogenous material, say water in plastic bags over the crew compartment, followed by a thin sheet of cadmium metal, would reduce neutron radiation intensity by about a factor of 5.' A factor of 5 reduction only reduces the neutron range by 15-20% because the dose drops off sharply with distance. But the factor of 5 calculation is false anyway, as Cohen explains on page 142, because the majority of the neutron dose is not coming straight down, but is coming from all directions due to the scatter of neutrons by the air, the ground around the tank, and the remainder of the tank itself! Kistiakowsky's stupidity is like trying to shield gamma radiation from fallout by wearing lead-soled shoes, in the mistaken belief that the hazard is due to fallout under your feet:
'Shielding a tank crew against neutrons is an enormously complicated problem. It is not solved by simply placing the shield over the crew compartment. By the time the neutrons reach the tank, they are bouncing around in all directions, and to protect the crew properly, the shielding will have to be placed around the sides of the crew compartment as well. As a consequence, the shielding weight begins to pile up: to a much greater level than Kistiakowsky realizes. ... The tank's mobility would be cut appreciably, as would the ability to swing the turret around to fire at acquired targets. In fact, were the tank to be shielded to a degree where the radiation was no longer the primary threat ... the added weight would cripple the tank's combat effectiveness.'
Another wild claim against the neutron bomb, made by Dr Herbert Scoville, Jr., which Cohen debunks (page 140), is that tank crews who are lethally irradiated will fight a 'Kamikaze' attack even more efficiently that they were fighting before, despite having radiation sickness. Cohen points out that they will not know exactly what their neutron dose is in a combat situation, and in any case the symptoms of radiation sickness will prevent their efficient execution of military functions.
Cohen further points out (pages 153-5) that two radiation accident victims who survived 400-600 cGy air doses (300-450 bone marrow doses): 'were back to normal some number of weeks [discharge from hospital at 2 and 6 weeks, respectively, and full recovery of strength at 10 weeks postexposure] after their accidents. They bore no scars from their mishaps (apparently not even emotional scars) and were able to pick up where they left off when they were irradiated. As to how these aftermaths compare with those resulting from being wounded by conventional weapons, if one so desires you can find out by visiting the nearest Veterans Administration hospital.'
On 11 November 1981, the Los Angeles Times printed an article called 'Neutron Weapons: an Agonising Death (I've seen it)', by Professor J. Garrott Allen at Stanford University Medical School, falsely claiming that the death of Dr Louis Slotin 9 days after a criticality accident in May 1946 indicates the radiation effects of a neutron bomb: 'The production of neutron weapons is probably as immoral a concept as human minds have yet devised.' Cohen debunks Allen on pages 156-7: Dr Slotin was touching a plutonium bomb core with his bare hands when he made it supercritical, so he got terrible localized exposures to his hands and arms, which were way higher than the doses you can get from a neutron bomb. This is why Dr Slotin had the painful radiation burns which Allen observed in treating him. Allen was dishonest in claiming that those radiation burns were analogous to neutron bomb exposures. In any case: 'Allen never mentioned the terrible burns that can result from ... the heat from fission battlefield nuclear weapons.'
On 10 September 1981, two months before Allen's notoriously inaccurate article was published, Cohen had written to the Secretary of Energy James B. Edwards, asking:
'Why is it, Mr Secretary, that after more than four years of intense, often acrimonious and almost always highly emotional, debate over the neutron bomb, the government has never put out an official statement to dispel the distorted technical charges which have been made about the weapon's effectiveness and alleged immorality? It seems to me that had this been done at the start, today we would not have the same anti-nuclear scientists making the same distorted charges; leaving the American people as confused as ever - and probably the Europeans as well.
'I would strongly suggest that DOE and DOD get together (as they did some 30 years ago, when they first issued The Effects of Nuclear Weapons to responsibly inform the American people what nuclear weapons were all about) and provide an official document spelling out the true facts of the issue.' (As we shall see, the declassification of Capabilities of Nuclear Weapons is a step in that direction.)
Above: the 14.8 megatons Castle-Bravo nuclear surface burst on 1 March 1954 at Bikini Atoll, about 20 seconds after detonation. If the Pentagon wanted to kill civilians in a nuclear war, it would have planned to use such nuclear explosions, instead of moving downward to the deterrence of 1 kt neutron bombs burst at 500 metres over Warsaw Pact tank concentrations. Above: damage to the personnel camp 17 miles away (on the other side of Bikini Atoll), from the 14.8 megatons Castle-Bravo test.
Above: the 3.8 megatons (50% fission) Redwing-Cherokee nuclear test air burst on 21 May 1956 at an altitude of 4,350 feet over Bikini Atoll, having been dropped from a B-52 bomber (the bomb was 34.5 inches wide, 136 inches long, and weighed 6867 lb). This is another way to produce maximum civilian casualties, in contrast to the neutron bomb.
I briefly reviewed the tremendous and excellent autobiography of Sam Cohen, Shame, earlier (click here). The Third Edition has now been released (click here for free PDF book file), with some obvious improvements. Conrad Schneiker kindly emailed the news, stating: 'The third edition features a new overview and postscript chapter by Charles Platt, plus an extremely provocative change of title. (I advised against something so outrageous, but you know how outraged Sam is about current events.)'
What is outrageous is the widely-held belief that dirty, high yield (300-400 kt or whatever) warheads stocked today, which would have fairly massive fallout, blast and thermal implications, are more moral to stockpile as a deterrent than 1-10 kt neutron bombs which are designed for air burst detonation to avert all local fallout hazards, and which release relatively little blast and heat flash since 80% of the energy from deuterium-tritium fusion is released as neutrons.
Obviously there is some fission also involved to start off the clean fusion reaction (but that is trivial for a yield of 1-2 kt, even if burst on the surface or shallow underground to maximise fallout, click here for experimental proof from nuclear tests surface burst, and here for shallow underground test data), and there is also the issue that some soldiers massed in fortifications or fighting vehicles will be neutron targets, but that's the only way to deter them. The public don't understand the fact that the neutron bomb has no collateral damage:
Cohen points out that the neutron bomb doesn't have the collateral damage of fallout, blast and heat effects that occurred in Hiroshima, but enhanced neutron flash radiation:
'in about a thousandth of a second it will seriously irradiate enemy soldiers (in tanks, self-propelled artillery vehicles, armored personnel carriers, in field bunkers, and most other places where they may be) out to a distance of about half to three-quarters of a mile for a warhead yield of a kiloton... Roughly half will die, most rather quickly from shock to the central nervous system. ... What doesn’t it do? Well, for start-offs, when the war is over the civilian areas — villages, towns, cities — will be in just about the shape they were in before it started. There will be no lingering radioactivity [residual doses from neutron induced activity in soil are insignificant compared to the flash dose of neutrons, and it decays quickly as in Hiroshima] to prevent occupation of these areas; in fact, they can be reentered almost immediately. (Compare this with every major war we’ve fought in this century, with what I saw in Seoul that affected me so deeply.)
'As for the enemy soldiers, the bad guys, who during a war we make out to be as barbaric as the troops of Attila the Hun (they usually are), those that die are dead; but that’s always been the main objective in battlefield conflict — to kill. As to how they die, which hasn’t been of real concern in conventional war, all I can say is I doubt whether the agony an irradiated soldier goes through in the process of dying is any worse than that produced by having your body charred to a crisp by napalm, your guts being ripped apart by shrapnel, your lungs blown in by concussion weapons, and all those other sweet things that happen when conventional weapons (which are preferred and anointed by our official policy) are used.' (Shame, online edition, p. 130.) - from earlier review.
'Groupthink is a mode of thought whereby individuals intentionally conform to what they perceive to be the consensus of the group. Groupthink may cause the group (typically a committee or large organization) to make bad or irrational decisions which each member might individually consider to be unwise.
'Groupthink ... is a rationalized conformity — an open, articulate philosophy which holds that group values are not only expedient but right and good as well. [2]
'Irving Janis, who did extensive work on the subject, defined it as:
'A mode of thinking that people engage in when they are deeply involved in a cohesive in-group, when the members' strivings for unanimity override their motivation to realistically appraise alternative courses of action. [3]
'... the Bay of Pigs Invasion as the archetype of the groupthink phenomenon. ... the decision to execute this disastrous military campaign was made with almost unanimous agreement by President John F. Kennedy and his advisors. These advisors were, almost without exception, very similar in background to the President ... General David M. Shoup, Commandant of the Marine Corps at the time and not part of the privileged group, predicted failure and enormous casualties for the invasion, and practically begged the President not to undertake it. Shoup's professional advice was ignored ... with disastrous results. ... In 2004, the USSenate Intelligence Committee's Report on the U.S. Intelligence Community's Prewar Intelligence Assessments on Iraq blamed groupthink for failures to correctly interpret intelligence relating to Iraq's weapons of mass destruction capabilities ...
'Causes and symptoms of groupthink
'Janis's "antecedent conditions" likely to encourage groupthink:
High stress from external threats with low hope of a better solution than the one offered by the leader(s)
High group cohesiveness
The persuasive strength of the group's leader
'His eight symptoms indicative of groupthink:
Illusion of invulnerability
Unquestioned belief in the inherent morality of the group
'Social psychologist Clark McCauley's three conditions under which groupthink occurs:
Directive leadership
Homogeneity of members' social background and ideology
Insulation of the group from outside sources of information and analysis ...
'One mechanism which management consultants recommend to avoid groupthink is to place responsibility and authority for a decision in the hands of a single person who makes the decision in private and can turn to others for advice. Others advise that a preselected individual take the role of disagreeing with any suggestion presented, thereby making other individuals more likely to present their own ideas and point out flaws in others' and reducing the stigma associated with being the first to take negative stances (see Devil's Advocate).'
Groupthink is clearly on display in the manner that string theorists operate.
Appendix A of the July 2004 Commission EMP report quotes from Thomas C. Schelling's Foreword to Roberta Wohlstetter's book Pearl Harbor: Warning and Decision, Stanford UniversityPress, 1962, p. vii:
'[There is] a tendency in our planning to confuse the unfamiliar with the improbable. The contingency we have not considered looks strange; what looks strange is therefore improbable; what seems improbable need not be considered seriously.'
This is true. Even when Hitler mobilized 100 divisions at the Soviet Union's border in 1941, Stalin was dismissive of all reports of preparations being made by the Nazis to invade the Soviet Union (this was because of the Nazi-Soviet peace-pact of 1939, creating a false sense of security to the USSR). Herman Kahn has explained in On Thermonuclear War (1960) how Pearl Harbor, Oahu, Hawaii (appropriately by coincidence also the centre of unpredicted EMP damage in the 1962 Starfish nuclear test) was supposedly immune from attack, because it was shallower than the textbook-stated minimum water depth for a torpedo. The Japanese simply made special torpedoes to use in the attack on the U.S. Pacific Fleet in 1941. (Even when America received advanced warning of the attack, its wishful thinking simply dismissed the warning as an error, so no warning was passed on, and the scale of the tragedy was maximised.)
Over 40 years, in 36,500 survivors monitored, there were 176 leukemia deaths which is 89 more than the control (unexposed) group got naturally. There were 4,687 other cancer deaths, but that was merely 339 above the number in the control (unexposed) group, so this is statistically a much smaller rise than the leukemia result.
Natural leukemia rates, which are very low in any case, were increased by 51 % in the irradiated survivors, but other cancers were merely increased by just 7 %.
Adding all the cancers together, the total was 4,863 cancers (mainly natural), which is just 428 more than the unexposed control group. Hence, the total increase over the natural cancer rate was 9 %, spread over 40 years.
(Compare these scientific facts to popular fiction in newspapers and widely published political books 'explaining' the horrific effects of nuclear weapons compared to other weapons, which claims there were 100,000 or 200,000 cancers. The real figure is 428.)
From the review of the 2nd edition of Sam Cohen's book:
More on the testing of clean tactical nuclear weapons as low air bursts here (for true air bursts there is no early fallout at all, apart from thunderstorms when it goes straight down the drain anyhow and is shielded underground - it is better to have the fallout underground than people sheltering underground!), surface bursts here, here and here, and shallow underground bursts (for earth-penetrator effects; destruction of buried targets without collateral blast and thermal radiation) see here (scroll down on to section headed 'ARE EARTH PENETRATORS A CLEAN ALTERNATIVE TO HIGH YIELD SURFACE BURST NUCLEAR WEAPONS?'). For it's inclusion by Philip J. Dolan in Capabilities of Nuclear Weapons EM-1, and by Samuel Glasstone in an article in Encarta 97, see here.
There are therefore numerous uses for neutron bombs in deterring war without risking indiscriminate collateral destruction and the massacre of civilians in the event of an explosion. The 'alternative' is high yield stockpiled warheads!
Update: Samuel T. Cohen, inventor of the neutron bomb, has died
... President Reagan ordered 700 neutron warheads built to oppose the massive Soviet tank force that had been strategically positioned in Eastern Europe. He viewed the bomb as the only tactical weapon that could effectively stop the tanks without also destroying much of the continent. The weapons were later dismantled in the face of widespread protests and the disintegration of the Soviet Union. ...
Samuel Theodore Cohen was born in Brooklyn, New York, on Jan. 25, 1921, to Austrian Jews who migrated to the United States by way of Britain. When he was 4, the family moved to Los Angeles, where his father worked as a carpenter on movie sets. Young Samuel suffered allergies, eye problems and other ailments, and his mother put him on a rigidly controlled diet, regular purges and daily ice-water showers to toughen him up, and fed him so much carrot juice that his skin was often yellow.
A brilliant student, he studied physics at UCLA, receiving a bachelor's degree in 1943. After joining the Army, he was posted to MIT for advanced training in physics and math, then selected for work on the Manhattan Project. Although he never received a doctoral degree, he calculated neutron densities on Fat Man, the bomb that was dropped on Nagasaki, Japan.
After World War II, he joined the RAND Corp. in Santa Monica and spent most of his career there. He said the inspiration for the neutron bomb was a 1951 visit to Seoul, which had been largely destroyed in the Korean War. In his memoir, he wrote: "If we are going to go on fighting these damned fool wars in the future, shelling and bombing cities to smithereens and wrecking the lives of their inhabitants, might there be some kind of nuclear weapon that could avoid all this?"
He designed the neutron bomb using pencil, paper and a slide rule given to him by his father for his 15th birthday.
Samuel T. Cohen, the physicist who invented the small tactical nuclear weapon known as the neutron bomb, a controversial device designed to kill enemy troops with subatomic particles but leave battlefields and cities relatively intact, died on Sunday at his home in Los Angeles. He was 89.
... He insisted that many critics misunderstood or purposely misrepresented his ideas for political, economic or mercenary reasons. ...
A graduate of the University of California, Los Angeles, Mr. Cohen was recruited while in the Army in World War II for the Manhattan Project, which developed the first atomic bomb at Los Alamos, N.M. After the war, he joined the RAND Corporation and in 1958 designed the neutron bomb as a way to strike a cluster of enemy forces while sparing infrastructure and distant civilian populations.
Fired via a missile or an artillery shell and detonated a quarter-mile above ground, his bomb limited death to an area less than a mile across, avoiding wider indiscriminate slaughter and destruction. ... its neutrons dissipated quickly, leaving no long-term contamination that could render entire regions uninhabitable for decades. ...
“It’s the most sane and moral weapon ever devised,” he said in September in a telephone interview for this obituary. “It’s the only nuclear weapon in history that makes sense in waging war. When the war is over, the world is still intact.”
Samuel Theodore Cohen was born in Brooklyn on Jan. 25, 1921, to Lazarus and Jenny Cohen, Austrian Jews who had migrated to the United States by way of Britain. His father was a carpenter and his mother a housewife who rigidly controlled family diets and even breathing habits (believing it unhealthy to breathe through the mouth). The boy had allergies, eye problems and other ailments, and for years was subjected to daily ice-water showers to toughen him up.
The family moved to Los Angeles when he was 4. He was a brilliant student at public schools and U.C.L.A., where he graduated in 1943 with a physics degree. He joined the wartime Army and was posted to the Massachusetts Institute of Technology for advanced training in mathematics and physics.
In 1944 he was tapped for the Manhattan Project to analyze radioactivity in nuclear fission. He worked on Fat Man, the bomb dropped on Nagasaki in 1945, days after Little Boy destroyed Hiroshima.
Mr. Cohen joined RAND in Santa Monica in 1947 and 11 years later designed the neutron bomb as a consultant to the Lawrence Livermore National Laboratory.
Motl wouldn't be allowed to write what he wanted on his blog if it wasn't for people like the Pope fighting the commies.
The Pope supported peace and awarded the neutron bomb inventor Cohen for deterring the 3-to-1 Warsaw Pact tank superiority in England.
Dear N,
I am still grateful to John Paul II for various things, but the communism in Czechoslovakia was primarily defeated by the Czechoslovak students like me and those who followed. It is not quite clear to me what mechanism are you imagining in Pope's victory over communism, except for his prayers.
Best Lubos Lubos Motl | Homepage | 06.17.06 - 9:11 am | #
Dear Lubos,
The mechanism: in 1979 the communist power was at its highest, they had achieved nuclear parity with the West and they invaded Afghanistan.
The Pope - unlike predecessors - took a strong line against it. Giving Cohen a medal for peace is not the mechanism I mean. Reagan deployed the neutron bomb in Western Europe.
The Warsaw Pact was already under enormous financial burdens.
Capitalism defeated communism by outspending on arms to deter them. This required the moral backing of the Pope, who was from Poland (which is probably more grateful than Czech Republic). Reagan sparked off the need for economic reform not only with neutron bombs but by "starwars" etc.
This means that they gave up trying to win the Cold War, and Gorbachev came to power to reform the commie economy and try to make consumer goods and sort out food shortages.
As soon as Gorbachev relaxed state police power in the Warsaw Pact, communism was able to collapse.
If the background situation was not relaxed as a result of the Pope and others condemning communism and supporting the arms race against it, it could have won.
Student protests are not going to be effective unless the regime is demoralized and relaxing its iron grip first as shown by the earlier failure in Prague, Czechoslovakia in 1968 and in other states where students were simply driven over by tanks or guns. (Hungary 1956, Tiananmen Square, China 1989.)
It was only because the Pope and Reagan had used the arms race to force economic reform on Gorbachev that you Czech students did not have to face the tanks of the Red Army.
Lubos Motl is right about the climate change manure because what the doom-sayers of climate change forget is that we're running out of fossile fuels anyhow!
Before the world is wrecked completely by global warming, we'll have run out of oil, coal, gas (North Sea oil is far more expensive than Arabic supplies because of the costs of oil rigs in the North Sea, and gas - "vapour" I suppose to USA readers to avoid confusion with gas(oline) - is seriously more expensive now that the market is opened up to Europe by a new gas pipeline, and if I buy a new home I'm getting all-electric heating, not the traditional piped gas heating currently used in most of the UK).
To combat global warming, go nuclear. Nuclear is clean, safe, and it is EVEN ECONOMICAL if you lower radioactive pollution horseshit propaganda and shoot crackpots who claim radiation is lethal.
Those people don't understand background radiation, or the effect of higher altitudes, air travel, etc on radiation exposure.
They think "natural" radiation is safe and "artificial" radiation from nuclear power is totally different.
The Health Physicists who work in the nuclear industry are a load of gormless, feeble, patronising fools who couldn't explain anything to anybody without making it sound like condescending pro-nuclear propaganda, which is why the situation continues.
They have no idea that physics and maths are well known, and that people can by and large understand radiation. They perpetuate the myths.
The FIRST thing physicists in the f***ing nuclear industry should put on their posters is the fact that on the Moon the natural radiation is 50 times higher than on earth, 1 mR/hr on Moon compared to 0.02 mR/hr on Earth (the earth's atomsphere shields most of the background radiation, which is 99% protons and alpha particles).
Then they should give the ACTUAL (not relative!) natural dose rates in different cities with different bedrocks and altitudes above sea level! The thorium rich beach sands of Brazil and India are more radioactive than 90% of the "nuclear waste" from the nuclear industry!
It is a wide range!!! Then, finally, they should show the lies about low level radiation by plotting the mortality in Hiroshima and Nagasaki and other long-term reliable studies as a function of dose.
It is true that massive doses severely increase leukemia rates, but it is a lie that small doese do so in proportion, or that other cancers are increases in the same way. Leukemia is a special problem, because the bone marrow is very susceptible to ionising radiation.
Particularly, high-LET (linear energy transfer) radiations like alpha and beta and also soft x-rays (which cause ionisation by the photoelectric effect) inside the body increase cancer risks, NOT low-LET radiation like gamma rays (unless the dose is really massive).
People should be aware that the more penetrating the radiation is, the less of it gets stopped by soft tissue in the body, so the LOWER the absorbed dose per unit of fluence!
The real dangers from low level radiation are from ingesting or inhaling soluble alpha and beta emitters, like radium and strontium-90 respectively, which get deposited in bone and can cause leukemia. Radon gas from the decay of radium is also a massive natural hazard, killing far more people than all the hundreds of megatons of 1950s nuclear tests or Chernobyl.
Chernobyl showed that iodine-131 causes a short term problem (half like 8 days) after an explosion, because it gets concentrated in milk and then in kid's thyroid glands and can cause lumps (mostly benign). The answer is simple: for the few weeks while milk is contaminated, either put it through an ion-exchanger to remove the iodine-131, or switch to using powdered milk or simply put the cattle in winter barns eating winter feed like hay so that they don't eat contaminated grass! Problem sorted!
Fewer than 1% of victims died due to cancer caused by radiation!!!!!
The maximum leukemia rate occurred in 1952 and ever since has been declining. There were no genetic effects above the normal rate in offspring of even highly irradiated survivors and cancer risks were carefully studied:
'The Life Span Study (LSS) population consists of about 120,000 persons who were selected on the basis of data from the 1950 Japanese National Census. This population includes ... atomic-bomb survivors living in Hiroshima or Nagasaki and nonexposed controls. ... all persons in the Master Sample who were located less than 2,500 meters from the hypocenter ATB were included in the LSS sample, with about 28,000 persons exposed at less than 2,000 meters serving as the core. Equal numbers of persons who had been located 2,500-9,999 meters from hypocenter ... were selected to match the core group by age and sex. ... As of 1995, more than 50% of LSS cohort members are still alive. As of the end of 1990, almost 38,000 deaths have occurred in this group, including about 8,000 cancer deaths among the 87,000 survivors. Approximately 430 of these cancer deaths are estimated to be attributable to radiation.'
"By an amazing coincidence, the configuration resembles a peace symbol with Earth at its centre."
Yes, it's the CND symbol, invented in by Gerald Holtom for the march of the Direct Action Committee Against Nuclear War from London to Aldermaston, Easter 1958.
I think it's a good thing to have peace, but there are issues about how best to get there. (Simple disarmament was tried in Britain in the 1920s and 1930s, but it just encouraged enemy aggression.)
Update 15 May 2007: there is an interesting interview of Samuel Cohen by the Wired journalist Charles Platt, "The Profits of Fear", where Platt admits:
"... Journalists were not much better. They could have learned the ethical basis for the neutron bomb easily enough if they cared to do so, but, they didn't care. They took the lazy way out, quoting cheap shots from peace activists' press releases, which never failed to tag the bomb as the "ultimate capitalist weapon." Cohen took grim solace when Leonid Brezhnev denounced him publicly as an "international war criminal," but the vilification he received in his own country was hard to endure.
"Confronted with bad press, venal politicians, and world leaders who still seemed hooked on the drama of weapons that would cause as much destruction as possible, Cohen concluded that neutron bombs would be built only if the United States got itself into a conventional war that imposed an intolerable financial burden while creating unacceptable casualties among American troops. As the years passed, the Vietnam War certainly began to fit this description. "We had close to a half million American casualties in Vietnam," Cohen recalls, "and by this time the Livermore laboratory had put in a proposal to Washington stating that they could manufacture a couple hundred neutron bombs. Of course, no one can predict the number of bombs that would produce any specific result, but I believe that considerably less than 200 neutron bombs could have ended that war."
"Since an outright retreat from Vietnam seemed unthinkable at this time, the situation invited a quick application of overwhelmingly superior military technology--which could now be achieved without targeting civilians or destroying the infrastructure that sustained them. Once again, however, Cohen found himself thwarted by theories and prejudices that made this unacceptable. The neutron bomb was still nuclear, the Vietnamese were Asian, yet even this wasn't the biggest issue. According to conventional wisdom, any small nuclear weapon was dangerous because the nation that used it would encourage other nations to use theirs, and a back-yard nuclear squabble would escalate to a full-scale nuclear war.
"This was like the theory that anyone who used marijuana would wind up using heroin. No evidence existed to support it. No national leader had ever threatened to respond with a big nuke if someone else launched a small one. Still, everyone was afraid that it could happen, and Cohen couldn't prove that it wouldn't."
Is there exist limit on size of H-bomb?From Brief story of time: Such conditions could occur in a very big hydrogen bomb: the physicist John Wheeler once calculated that if one took all the heavy water in all the oceans of the world, one could build a hydrogen bomb that would compress matter at the center so much that a black hole would be created. (Of course, there would be no one left to observe it!).So what type of tamper he consider ?Mass of uranium on Earth not enough to compress ~4.8*10^13 tons of deuterium.How many stages this would be? Its evidence that multi-stage designs have far better yield-to weight ratio than smaller ones.Another side: George Dyson when he described USAF Doomsday Orion proposal in BBC doku:To mars by A-bomb says that its bomb (1650 metric tons) largest physically possible.What this mean?Probably this bomb would have largest physically possible yield-to weight ratio for tn-weapons(~100 megaton per ton)?Idea was to detonate this at very high alltitude (~400km) at Soviet Union,this would spread fires over entire hemisphere and probably destroy ozone layer.Gold is better for compression than uranium?What this fireball would be ,X-ray-fireball ?Probably fireball would be spread over entire hemisphere.
Yes, you can distil deuterium from sea water and in principle use it to make an arbitrarily large explosion. Regarding the problems of using a small fission bomb to compress and ignite the (extremely large) deuterium capsule in such a design, there are two obvious possibilities:
(1) You just make the deuterium capsule a very long cylinder (along its long axis), and put the small fission bomb at one end. The X-rays can't ablate and compress the entire long secondary simultaneously, but they will get the reaction started for the first few feet length near one end of the cylinder. The fusion energy released at that end will be accompanied by X-rays, which will ablate and compress the next few feet of the length of the deuterium cylinder's metal pusher, and so on, like the burning of a fuse. The efficiency will be expected to increase as more and more deuterium is fused.
Herman Kahn discusses these ideas under the category "doomsday machines". However, they are undeliverably heavy, exceedingly expensive (deuterium is very expensive to distil in massive amounts, it's not as free as the sea water which contains it; sea water also contains gold but it's not worth the expense to extract it except as a byproduct of some desalination plant operations), and unpractical for military purposes. Maybe the long-line version (type 1 above) could be useful for economically digging a very long, very big, extremely deep canals, making huge tunnels through massive mountain ranges, and similar geophysical engineering, once the current nuclear hysteria in the media dies down a little. The other design could be used for really huge "orion" type nuclear explosion pulse accelerated spacecraft.
As for histeria-I'm completely shocked not only histeria by media,but "works" by FAS staff (Kristenson) and his comrades in NRDC. They give initially absurdly small yields for some US weapons(this was corrected in 2009) ,but 1.1 mt yield for mk28Y1(strategic version)was a yield of clean version,est.yield prior test was 800kt,but this is only 1/5 of full yield.Also numbers,it seems that numbers of mk39-s and mk-41-s were higher than 700 and 500 respectively.Initial plan for mk41s would be as high as number of heavy bombers*2,but in 1960 under pressure of some Joint Chiefs of Staff Eisenhower approved replacements of loadings-prior each bomber carry 2 type B ,after this was a mix of B and D (4 per bomber)+Hound Dogs were deployed ,however only 54 by end of 1960.But ,it seems that number of mk-41s was somewhat larger.
Another ,their's constant false -absurdly exaggeration of effects,totaly using Postol's falsehoods,lying about impossibility of missile defence and etc.They finally claimed that ....... 368 w-88 airbursts required to kill............25% population of China.They against any new weapons and scientific work on its and related technologies,for complete eliminations of nuclear weapons as soon as possible,this would be a mistake.I'm believe that China since 2025 would be a very big problem.
What annoys me about NRDL is that they got the 1992 version of Brode's "Capabilities of Nuclear Weapons" declassified under the freedom of information act, as William Arkin reported in the July 1997 Bulletin of Atomic Scientists, and now they are sitting on it, effectively keeping it secret! When will they digitalize it and put it online as a PDF file?
Britain’s first hydrogen bomb test, Short Granite, had a fusion stage physically separate from the 30-kt fission stage, but the fusion charge was a spherical layer cake; it had 14 concentric layers 0.86 mm to 2.47 cm thick, alternately lithium-6 deuteride and uranium-238. Dr William Penney designed the first version of this bomb in September 1955, as two spherical units, a fission bomb and a fusion charge, within a single cylindrical bomb casing. Penney’s design only yielded 300-kt when tested on 15 May 1957, because the 14 thin shells of uranium and lithium deuteride were too thin to allow fission and fusion reactions. Where they were mixed up by instabilities during compression, the resulting mixture prevented fusion reactions.
However, this low yield was sorted out by redesigning the spherical secondary (fusion) stage so that it contained a small U-235 core surrounded by just one thick lithium-6 deuteride layer and finished with an outer shell of U-238. This redesign was tested on 8 November containing a 45-kt fission primary with a beryllium reflector and yielded 1.8-Mt.
Lorna Arnold, the official historian of Britain’s nuclear tests, states in the book Britain and the H-Bomb (Palgrave, New York, 2001, p. 160) that in the fission primary the chemical explosive implosion system took 70 microseconds (from electrical detonation time) to achieve maximum compression of the plutonium core. Arnold states that the x-ray energy it released compressed the fusion stage diameter by 2.7 times, thereby increasing its density by 20 times within a time of 2 microseconds. This is to be compared to a maximum density increase of only 8 times in the much smaller fission core. It is interesting that the same bomb materials were rearranged to give another design with the fission and fusion stages placed closer together (almost touching), and this was tested with a yield of 3-Mt on 28 April 1958. This design was only 3.2 metric tons and therefore gave nearly 1-kt/kg. It was manufactured as Yellow Sun Mk1 and was stockpiled by the RAF from 1959-62.
Closer spacing of the two stages therefore increased efficiency and thus the yield of the weapon by 67 %, instead of reducing the yield by causing the shock to upset the fusion stage (as you might expect). The speed of the x-ray mechanism is so much faster than the material shock wave, that the latter can be forgotten in the design process. In the 1950s American thermonuclear weapons, the secondary charges were cylinders, not spheres as used in British weapons. The American W-28 weapon uses a tapering cylinder, which is widest near the fission bomb, but becomes narrower at greater distances to allow for the fact that the x-ray intensity falls with distances so the parts of the fusion stage further from the fission bomb get less compression force. To keep the compression factor constant, the fusion charge cylinder must become narrower with increasing distance from the x-ray source.
After the exchange of American-British research on nuclear weapons in 1959, America developed the W-50 warhead that contained a 410-kt nuclear explosive with a spherical second stage like the British devices. The W-50 nuclear component mass was 186 kg, 1.12 m long and 39 cm in diameter. It was first tested as Aztec on 27 April 1962, and was also used for the high altitude tests that same year, Kingfish and Bluegill. America also used spherical fusion stages in its most recent warheads, the W-87 and W-88 (their blueprint schematics were released after Dr Wen Ho Lee allegedly emailed them to communist China). The W-87 is very similar to the classic British thermonuclear design, with a spherical fission bomb beside a spherical fusion charge containing a U-235 core surrounded by a shell of lithium-6 deuteride, and topped off with a U-238 pusher. The W-88 is somewhat different in that it uses a prolate-spheroid shaped implosion fission bomb, and the fusion charge differs from that in the W-87 because it contains a U-235 pusher instead of U-238.
It seems fo me that Soviet tsar bomb was a not 3-stage device,but a cluster of smaller ones(probably 8*12.5Mt). Soviet Union never considered this as weapon,one proposal was for using its as mine.They considered 30mt and 50mt for UR-500 and R-56 respectively,however later canceled this.See:Khrushchev, Sergei, Nikita Khrushchev and the Creation of a Superpower, Pennsylvania State University, 2000. I believe this book a best source on soviet weapons and plans to 1965.For later weapons, mostly ICBM warheads i believe reliable data not exist in declassified world.
Modern compact MIRVed ICBM warheads like the W87 and W88 have to use spherical/prolate shaped secondaries as is made clear by the unclassified Cox Report on the Wen Ho Lee warhead blueprint leaks.
These spherical shaped secondary stages were first tested in the 1950s by Britain, which declassified the technical details for Arnold's published official history of British research on the H-bomb.
Therefore, there is some information available. Like Dolan's 1972 EM-1, Bridgman makes the point very clearly in his 2001 DTRA book, Introduction to the Physics of Nuclear Weapons Effects that civil defense countermeasures depend on an understanding of the general construction of different kinds of nuclear weapons (pure fission, boosted, gun assembly, and different kinds of thermonuclear weapons like neutron bombs, etc.), because the weapon design determines (1) the output of initial nuclear radiation, which is a key casualty causing agent for low yield weapons once you duck and cover from the thermal flash, blast winds, and flying bebris, (2) EMP (which depends primarily on the prompt gamma output, which depends on the inelastic neutron scatter in the bomb materials, the fission yield, and the bomb outer casing shielding factor), and (3) fallout (neutron induced activities like U237 and Np239 from neutrion capture by U238 greatly affect fallout radiation rates and gamma spectra, so the shielding protection factor during the first few weeks depends critically on bomb design, the kind of tamper or pusher, etc.). Hence the threat from fallout depend on the bomb design; early relatively clean bomb tests in 1956 (Redwing-Navajo and Redwing-Zuni) for example used lead pushers which led to neutron induced lead nuclides in the fallout, while later relatively clean bombs tested in 1958 and later used tungsten pushers, leading to important contributions to fallout radiation by tungsten nuclides due to neutron capture in the tungsten. Tungsten is preferred to lead for use as an ablative pusher because it has nearly double the density of lead and is roughly the density of uranium (specific densities for uranium and tungsten are around 19 grams per cc, compared to only about 11 for lead).
So for real appreciation of civil defense, you need an up to date understanding of bomb design implications for the INR, EMP and fallout effects.
Redwing-Zuni was a clean version of Bassoon device ,its full yield was a 25mt,later deployed as mk-41.
Poplar device was not related to mk-41,its was another device for class B weapon.Its full yield was 20 mt,test yield of clean version was predicted to be a 7mt,in reality-9.3mt.Probably clean version was considered as addition to mk-41,since as its clean version was only 3.5mt.However never deployed.In reality a large number of devices(both 2 and 3-stage) was studied both by LANL and LLNL for new class B warhead (20Mt,10000 pounds).But Bassoon device was a cheapest .And most probably its enlarged version was considered as basis for new Class A weapon(25000 pounds,60Mt).
You don't need any U-238 in the casing at all. Redwing-Navajo tested at Bikini Lagoon in 1956 had a lead tamper in place of U-238. Total yield 4.5 Mt and fission fraction was 5% or 225 kt, which must have been the yield from full fission of the primary stage. It can't have contained any significant fission "spark plug" in the fusion stage. It still worked fine. Obviously, the heating of the secondary (fusion) stage is reduced by the removal of the fission of a U-238 tamper or pusher around it. So replacing U-238 with lead or tungsten must reduce the efficiency of the fusion reaction, requiring a heavier bomb for the same overall yield.
Ordinary stable gold or Au-197 has a density of 19.32 g/cc, which is similar to uranium.
The neutron capture cross-section for this stable gold Au-197 is only 0.09 barn for 1 MeV fission spectrum neutrons, but seems to drop to about 0.01 barn at 5 MeV and presumably less at higher (fusion neutron) energies, according to Fig 1 in the 1976 translated Russian report http://www-nds.iaea.org/reports-new/indc-reports/indc-ccp/indc-ccp-0082.pdf. I'm not near a library that has the Chemical Rubber Company (CRC) reference work, CRC Handbook of Chemistry and Physics, which is usually the best handy compilation of nuclear data on all the different isotopes, so I can't check that or find out what the neutron inelastic scatter cross-section for gold is. Two 1956 clean (5% and 15% fission) Redwing tests both used lead tampers, while the clean American tests in 1958 and 1962 both used tungsten pushers (tungsten is better than lead, since it has a much higher density).
Gold has the obvious disadvantage of being expensive. Normal tungsten, which is mainly W-184, is much cheaper than gold. Tungsten has of course a very high melting point, 3410.0 °C which is why it is used in light bulb filaments (the melting point is much higher than ordinary silicate soil), so it's neutron capture derivatives behave as super-refractory or "enriched" nuclides in early fallout from surface bursts. However, this doesn't matter for air burst neutron bombs.
It seems that this device that Hawking mentioned and Wheeler studied-largest physically possible Teller-Ulam bomb.Probably Wheeler's goal was to determine upper limit of Teller-Ulam design.
It interesting to estimate its yield,since as deuterium burning would be only first stage ,later helium burning, carbon burning and etc.And other means,such as plasma would be very high-energic.and heavy.

Regarding your joke. No, I'm not that stupid. I've read Glasstone's Controlled Thermonuclear Reaction and I know how the sun works - SLOWLY!!!!
Even under the immense compression of the sun's mass and gravity, the nuclear fusion reaction rate per particle is extremely low. This is why it lasts billions of years.
There is no way you are going to burn helium or carbon or anything heavier!
Carbon burning requires the triple alpha process: three helium-4 nuclei have to come together (fusion can't proceed effectively by purely binary processes beyond beryllium, due to a bottleneck in the chain). There is no way you can achieve any efficiency with this process over the timescale of a nuclear explosion.
You're talking about building a new star, a new sun, not a bomb.
True, old heavy stars can explode with a supernova. Betelgeuse, 640 light years away, is supposed to have gone supernova around 1370 AD and its flash is predicted to be seen this year, if they have their sums right.
However, supernovae require immense masses so that a heavy core builds up, creating very heavy elements by successive neutron captures (the R or rapid process), right up to uranium and plutonium. People are never directly going to make exploding star. Maybe eventually there will be robot spacecraft like giant dumper trucks in space that can pile together material to make stars and supernovae, but that's so far off we don't need to worry about it. No terrorist is going to do it in their back room!
Earth 'to get second sun' as supernova turns night into day By David Gardner Last updated at 5:53 PM on 22nd January 2011
The Earth could soon have a second sun, at least for a week or two.
The cosmic phenomenon will happen when one of the brightest stars in the night sky explodes into a supernova.
And, according to a report yesterday, the most stunning light show in the planet’s history could happen as soon as this year.
Cosmic phenomenon: The Earth could soon see two suns - just like Luke Skywalker saw on Tatooine in the Star Wars film (pictured)
Earth will undoubtedly have a front row seat when the dying red supergiant star Betelgeuse finally blows itself into oblivion.
The explosion will be so bright that even though the star in the Orion constellation is 640 light-years away, it will still turn night into day and appear like there are two suns in the sky for a few weeks.
The only real debate is over exactly when it will happen.
In stellar terms, Betelgeuse is predicted to crash and burn in the very near future. But that doesn’t necessarily mean you have to rush out and buy sunglasses.
Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland in Australia, claimed yesterday that the galactic blast could happen before 2012 – or any time over the next million years.
‘This old star is running out of fuel in its centre,’ Dr Carter told te Austalian website news.com.au.
‘This fuel keeps Betelgeuse shining and supported. When this fuel runs out the star will literally collapse in upon itself and it will do so very quickly.
‘This is the final hurrah for the star. It goes bang, it explodes, it lights up - we’ll have incredible brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all,’ he added.
Look out: Betelgeuse, which is in the Orion constellation, is set to blow itself into oblivion - which will give the effect of two suns in the sky for us on Earth
The Internet is abuzz with doomsday theories linking the supernova to the Mayan calendar’s prediction of an Armageddon in 2012, fuelled by the association of the word ‘Betelgeuse’ with the devil.
But experts claimed that even if the big bang is looming, it will still happen way too far from Earth to do us any harm.
‘When a star goes bang, the first we will observe of it is a rain of tiny particles called nuetrinos,’ said Dr Carter.
‘They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99% of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever.’
When it happens, the Betelgeuse supernova will almost certainly be the most dramatic ever seen.
It is the ninth brightest star in the night sky and the second brightest in the constellation of Orion, outshining its neighbour Rigel – or Beta Orionis – only very rarely.
It’s distinct orange-red colour makes it easy to spot in the night sky.
If it was at the centre of our solar system, its surface would extend past the asteroid belt, wholly engulfing Mercury, Venus, Mars and the Earth.
There are a couple of minor flaws in the newspaper story just quoted about the forthcoming Betelgeuse supernova. First, it's not proved exactly what the effects will be. Even very weakly interacting particles like neutrinos (misspelled in the article above) can kill you if you get a massive dose. Normally, astronomers see supernovas billions of light years away. This one will be only 640 light years away, that we know for sure. If you do the inverse square law to compare the radiation dose from a supernova 640 light years away to 1,000,000,000 light years away, (1,000,000,000/640)^2 = 2.4 * 10^12. So it's a million million times stronger. The supernova continues radiating radiation at a high rate for days, so it's not just the people on the side facing the initial flash who are exposed.
I'd like to check actual dose estimates, with error limits, before agreeing that we are safe from such a relatively nearby supernova just 640 light years away. People can be protected in principle by the earth's mass, by staying on the opposite side of the earth (in an aircraft flying against the direction of the earth's rotation).
Another thing is the date of the supernova. They can't be sure exactly when it will blow.
Of course neutrinos can't be efficiently shielded by the earth's mass because they are so extremely penetrating, but the light velocity gamma radiation and slower moving charged particle radiation (which will take years to arrive) can be efficiently shielded this way.
It's usually believed that a supernova would need to be within 25 light years of us to kill everyone by muon radiation, but there are various assumptions in the calculations that leave some questions unanswered.
The red giant Betelgeuse, once so large it would reach out to Jupiter's orbit if placed in our own solar system, has shrunk by 15 percent over the past decade in a half, although it's just as bright as it's ever been.
"To see this change is very striking," said retired Berkeley physics professor Charles Townes, who won the 1964 Nobel Prize for inventing the laser. "We will be watching it carefully over the next few years to see if it will keep contracting or will go back up in size."
This is not joke. In sun pressure only -2.4*10^16 Pa, density- only 150g/cc. To reach a BH density in this bomb (assuming mass of U-238 tamper -4*10^15 tons)density must be at least ~10^40g/cc,pressure-10^53Pa,T=10^19K or 10^6Gev.Matter would be crushed to pre-quark level. Even in core of neutron star-pressure-10^33 Pa,density-10^14g/cc, T=10^12K or 100 Mev. In 25 solar mass type II supernova silicon burning occurred at density-10^8g/cc, T=2.5*10^9k,with duration of 5 days. Very large stars with mass larger than 260 solar masses directly collapse in black holes and generate 10^54 erg jets. There explosive Si and O burning and far greater pressures than in ordinary supernovas. But in this device density far larger than in above examples, far larger than it needed to burn any element. In certain conditions slow processes would be very fast.
"1.1 Primordial Black Holes We now have good observational evidence for black holes from stellar masses up to super-massive holes of 108 to 1010 solar masses and maybe even more. However, one can also speculate on the possible existence of black holes of much lower mass. These are the holes for which quantum effects can be important. Such holes could not form from the collapse of normal baryonic matter because degeneracy pressure will support white dwarfs or neutron stars below the Chandrasekhar limiting mass. One can express this limiting mass as mPlanck(mPlanck/mbaryon)2. Its value is about a solar mass, which might seem a coincidence, but there are good anthropic principle reasons why stars should be just on the verge of gravitational collapse. This limiting mass applies only to the formation of black holes through the gravitational collapse of fermions. In the case of bosons the limiting mass is given by mPlanck(mPlanck/mboson). To form a black hole by the gravitational collapse of bosons, they need to have a non-zero mass and either be stable or have a fairly long life. About the only candidate is the axion, which might have a mass of about 10−5eV. In this case the limiting mass would be about the mass of the Earth, which is still quite high, and too large for quantum effects to be observable. To get black holes that are significantly smaller, one could not rely on gravitational collapse, but would have to shoot matter together with high energies. John Wheeler once calculated that if one made a hydrogen bomb with all the deuterium from the oceans, the centre would implode so violently that a little black hole would be formed. Perhaps fortunately, this experiment is unlikely to be performed. Thus the only place where tiny black holes might be formed is the early universe." From paper:S.W.Hawking and R.Bousso,Primordial black holes :Tunneling vs.No Boundary Proposal. at ArXiv:gr-qc/9608009 Even my estimates would be very conservative.
Hawking produces a lot rubbish based on first-quantization, such as his false claim that black holes should radiate irrespective of their charge.
Black holes are a very convenient hiding ground for egotists who don't want to understand physical mechanism.
Disproof of Hawking's general claim that black holes radiate
Schwinger in 1948 showed that pair production doesn't occur throughout the vacuum of space, but in electric fields >1.3*10^18 volts/metre. This threshold for pair-production is vital for vacuum polarization to stop varying the electronic charge below the IR cutoff in 2nd quantization (QFT), so it destroys Hawking's heuristic explanation for Hawking radiation from uncharged black holes.
The mechanism is that pair production occurs at the event horizon, with one fermion in the pair falling into the black hole, and the other escaping and eventually annihilating with an opposite charge to give a gamma ray (nobody has ever seen this alleged gamma radiation from a black hole, it's conveniently too small to observe above the gamma ray background in space from other sources!).
My argument using Schwinger's 1948 discovery in QFT black holes cannot radiate electrically neutral radiation such as gamma rays. Hawking's heuristic mechanism is false, because you need an electric field above 1.3*10^18 v/m at the event horizon, which means the black hole must be electrically charged in order to radiate anything by Hawking's heuristic mechanism. Things don't happen without a mechanism in QFT.
So uncharged black holes have 0 v/m electric field at their event horizons and emit no gamma rays (Hawking radiation), because there's no pair production there.
If we instead model a fermion as a charged tiny black hole, then it turns out that the electric field strength at its event horizon radius (2GM/c^2) is above the Schwinger's threshold for pair-production, so in this case Hawking's heuristic black hole radiation mechanism (albeit in modified form) does operate: the fermion will radiate charged virtual fermions as radiation, and these virtual fermions will have a charge the same sign as the real fermion in the core (the virtual fermions of sign opposite to thet of the real fermion core will fall into the black hole core). The interesting thing here is that two similar charged fermions travelling in opposite directions cancel one another's magnetic field vectors and thus cancel out the magnetic self-inductance that would otherwise prevent propagation. So massless off-shell (virtual) fermions can be exchanged between similarly charged particles, so that there is an equilibrium of exchange radiation. In this way, you can have charged fermions moving in opposite directions superimposing to create a composite field which is similar to a charged boson. I.e., the opposing half integer spins of each component can add to give bosonic spin.
In fact there not a Brief History of Time was a first mentiotion of this Wheeler's calculation(simulation) This was a : William J. Kaufmann, "Observing Astronomers: An Interview with Dr. Stephen W. Hawking"; Mercury 4 (November/December, 1975):13-16.
There was before Morland's case ,so he stated simply :Dr. John A. Wheeler estimates that a black hole of mass 10^9 kilograms might be generated artificially by the controlled thermonuclear fusion implosion of approximately 5 x 10^15 kg of deuterium."
Hansen stated that in USSR Teller -Ulam design was known,but this likely that among scientists,Novikov ,of course know this ( he was a Hawking's friend and Zeldovich (a Soviet Wheeler) protege) as Hawking himself.
Its most likely that this was a detailed simulation of such explosion.But mechanism would be more complicated than i'm believed .
10^9 kg-this is probably a uranium sphere in the centre of the bomb.
You are actually think that in the 1970-s it was impossible to simulate explosion of a such device ?
As ,for SUPER ,from Anne Fitzpatrick Teller’s Technical nemeses: The American Hydrogen Bomb and Its Development within a Technological Infrastructure” (TECHNE, Volume 3 No. 3, Society for Philosophy and Technology, Spring 1998), Part.1.
"The idea for a thermonuclear weapon occurred in 1941 to physicist Enrico Fermi one afternoon after lunching with Edward Teller in New York, when the Italian physicist pondered aloud about whether or not an atomic weapon, which was already in prospect, might be used as a trigger for a deuterium (D) weapon. In principle, a bomb that fused hydrogen to helium was far more economical and would produce a much greater explosion than a fission device. Inspired by Fermi's suggestion, Teller took up the cause of exploring a fusion weapon (see Rhodes, 1986, and Rhodes, 1995). Igniting deuterium alone would require temperatures of hundreds of millions of degrees, so Teller's colleague Emil Konopinski suggested that tritium (H3) be added to the mixture to lower the ignition temperature. These ideas became the basis of the "Super" weapon—a fusion bomb that in principle would create an explosion on the order of megatons.The idea was exceedingly difficult to understand. During the war Teller and his group attempted to work out the Super theory analytically (by hand), only to find out it was more complex than anyone, even Teller, had originally imagined. One major obstacle to the Super appeared in the form of energy dissipation. The incredible speed of all the reactions inside the deuterium would make it difficult to deliver the energy needed to reach the ignition point in a short time. Furthermore, the Inverse Compton Effect would cause cooling of the hydrogen electrons by collisions with photons coming from the fission initiator."
Part.2. "Hydrogen bomb calculations involve charged particles in addition to neutrons. Ignition of the Super required heating the material to a critical temperature rather than assembly of a critical mass (see Metropolis and Nelson, 1982, p. 355). Thus, calculating whether or not the Super could be ignited was a high hurdle; so was calculating whether or not a cylinder of deuterium, if ignitable, would be self-propagating and burn. These two aspects constituted what came to be known at Los Alamos as the "Super Problem." How could the Super problem be calculated? Enter mathematician John von Neumann, who had worked at Los Alamos during the war, and was not only aware of but intrigued by the prospect of a fusion weapon. Von Neumann arranged to have the Super problem run on ENIAC. PHIL & TECH 3:3 Spring 1998 Fitzpatrick, Teller's Technical Nemeses/13 Only the first part (ignition) of the Super problem was run on the ENIAC in 1945 and 1946. The entire calculation was meant to predict the behavior of deuterium-tritium systems corresponding to various initial temperature distributions and tritium concentrations. Collectively, the calculations attempted to predict whether or not a self-sustaining nuclear reaction would occur and ignite a cylinder of pure deuterium. The calculations were only one-dimensional. Because of the ENIAC's memory limits, several effects had to be left out of the problem. Though the Los Alamos problem was the most complicated of its time, even using 95 percent of the ENIAC’s control capacity, it did not truly answer the question of whether or not a Super could be ignited, much less propagate (see Harlow and Metropolis, 1983). Mathematician Stanislaw Ulam once gave his opinion on this calculation: The magnitude of the problem was staggering. In addition to all the problems of fission . . . neutronics, thermodynamics, hydrodynamics, new ones appeared vitally in the thermonuclear problems: the behavior of more materials, the question of time scales and interplay of all the geometrical and physical factors. . . . It was apparent that numerical work had to be undertaken on a vast scale (quoted in Aspray, 1990, p. 47). The difficulty of the problem exceeded the technology of the time. Even Teller, optimistic about the Super's feasibility, realized this and acknowledged ENIAC’s limitations. Teller recommended that attention be paid to developments in high-speed electronic calculators; thermonuclear calculations so far indicated that the complexity of the problems required at least an instrument like the ENIAC. In 1946, however, there simply were no other large machines available to Los Alamos besides the ENIAC. The Super problem would have to wait. Far from Los Alamos, construction of large computers was underway— slowly, and most would not be ready for several years. Since other new computers did not seem to be available quickly enough, the Los Alamos laboratory did not want to wait and began work building its own electronic digital computer. It was intended to be an exact copy of one that von Neumann was building at the Institute for Advanced Study (IAS) in Princeton."
Part.3. "Teller and his colleagues had hoped that either the IAS computer or the Los Alamos equivalent would be able to carry out a full simulation of the Super by 1949 or 1950, but construction on both computers fell way behind schedule. Growing impatient for any electronic machine to be ready, Ulam and University of Wisconsin mathematician C. J. Everett attempted to solve the ignition part of the Super problem with slide rules and hand computers, doing simplified calculations; still, they were not certain if the device would ignite or not, even though their results looked negative. (See Mark, 1974, and Ulam, 1976.) This was a problem, then, that weapons scientists felt could not be solved with any certainty analytically—at least in a reasonable amount of time. Von Neumann once estimated that completing a hand computation of the Super problem would require 100 hand computers and 4 years time. Teller wrote to von Neumann in May, 1950, lamenting that the laboratory was in a "state of phenomenal ignorance" about the Super. At this time there was still no machine calculation which had unquestionably proven nor disproven the feasibility of the Super, and Teller believed that this ignorance was due to the lack of fast computers. (Personal accounts of some of these difficulties can be seen in Bethe, 1982, and Los Alamos Historical Society, 1996.) Teller was disillusioned and depressed by the end of 1950 because his Super weapon was still not proven either to be workable or not. Moreover, Teller and his colleagues were under more significant political pressure to at least test a hydrogen weapon now that the Soviet Union had demonstrated its attainment of an atomic weapon. At Los Alamos, Ulam produced the first breakthrough to a workable but very different thermonuclear bomb, which he presented to Teller in January 1951. Subsequently, Teller and a young protégé, Frederic DeHoffman, produced a second crucial part of the new thermonuclear configuration. Teller named this device the "Sausage"—perhaps ironically, as an easier device to calculate than the Super configuration (see Hewlett and Duncan, 1972). Collectively, the ideas of Ulam, Teller, and DeHoffman comprised a new thermonuclear system that appeared viable on paper. It is also more commonly known as the Teller-Ulam configuration. But even the Sausage would have to be calculated and tested. To expedite calculations and to help Los Alamos overcome its shortage of theoretical help, Teller's friend and colleague, John Archibald Wheeler, had set PHIL & TECH 3:3 Spring 1998 Fitzpatrick, Teller's Technical Nemeses/15 up his own group at Princeton University to calculate part of the new thermonuclear configuration, since the laboratory needed as many available electronic machines as it could get. Wheeler's secret project was code-named "Matterhorn-B" (B for bomb), and that is where Sausage calculations were done, and two-dimensional hydrodynamic problems began to indicate the feasibility of the burning of deuterium in the Sausage. In the spring of 1952, the Los Alamos computer—the MANIAC (Mathematical and Numeric Integrator and Calculator; "Gamow" was its alternative name)—was completed, and it too was instead used for cylindrical radiation implosion calculations for the Sausage. These hinted at success for the upcoming Ivy Mike test in November, 1952, which yielded proof of Teller's fantasy of a multimegaton explosion. By choosing to develop the radiation implosion Teller-Ulam configuration, nuclear weapons scientists bypassed the Super problem. The Teller-Ulam configuration, although itself a difficult model to calculate, was easier to compute than the Super, a full calculation of which was not done on a computer until the late 1960s on the Control Data Corporation's 6600 computers."

Weapons scientists were bound by the limits of technology and thus had to adjust their research program under political pressure—with the limits of the technological infrastructure in mind."

How to achieve peace through tested, proved and practical declassified countermeasures against the effects of nuclear weapons, chemical weapons and conventional weapons. Credible deterrence through simple, effective protection against invasions and collateral damage. Discussions of the facts as opposed to inaccurate, misleading lies of the "disarm or be annihilated" political dogma variety. Hiroshima and Nagasaki anti-nuclear propaganda debunked by the hard facts. Walls not wars. Walls bring people together by stopping attacks by "divide and rule" style divisive terrorists, contrary to simplistic Vatican propaganda.
Historically, it has been proved that having weapons is not enough to guarantee a reasonable measure of safety from terrorism and rogue states; countermeasures are also needed, both to make any deterrent credible and to negate or at least mitigate the effects of a terrorist attack. Some people who wear seatbelts die in car crashes; some people who are taken to hospital in ambulances, even in peace-time, die. Sometimes, lifebelts and lifeboats cannot save lives at sea. This lack of a 100% success rate in saving lives doesn't disprove the value of everyday precautions or of hospitals and medicine. Hospitals don't lull motorists into a false sense of security, causing them to drive faster and cause more accidents. Like-minded ‘arguments’ against ABM and civil defense are similarly vacuous.
‘As long as the threat from Iran persists, we will go forward with a missile system that is cost-effective and proven. If the Iranian threat is eliminated, we will have a stronger basis for security, and the driving force for missile-defense construction in Europe will be removed.’
‘The [ABM] treaty was in 1972 ... The theory ... supporting the ABM treaty [which prohibits ABM, thus making nations vulnerable to terrorism] ... that it will prevent an arms race ... is perfect nonsense because we have had an arms race all the time we have had the ABM treaty, and we have seen the greatest increase in proliferation of nuclear weapons that we have ever had. ... So the ABM treaty preventing an arms race is total nonsense. ...
‘The Patriot was not a failure in the Gulf War - the Patriot was one of the things which defeated the Scud and in effect helped us win the Gulf War. One or two of the shots went astray but that is true of every weapon system that has ever been invented. ...
‘President Bush said that we were going ahead with the defensive system but we would make sure that nobody felt we had offensive intentions because we would accompany it by a unilateral reduction of our nuclear arsenal. It seems to me to be a rather clear statement that proceeding with the missile defence system would mean fewer arms of this kind.
‘You have had your arms race all the time that the ABM treaty was in effect and now you have an enormous accumulation and increase of nuclear weapons and that was your arms race promoted by the ABM treaty. Now if you abolish the ABM treaty you are not going to get another arms race - you have got the arms already there - and if you accompany the missile defence construction with the unilateral reduction of our own nuclear arsenal then it seems to me you are finally getting some kind of inducement to reduce these weapons.’
Before the ABM system is in place, and afterwards if ABM fails to be 100% effective in an attack, or is bypassed by terrorists using a bomb in a suitcase or in a ship, civil defense is required and can be effective at saving lives:
‘Paradoxically, the more damaging the effect, that is the farther out its lethality stretches, the more can be done about it, because in the last fall of its power it covers vast areas, where small mitigations will save very large numbers of people.’
‘The purpose of a book is to save people [the] time and effort of digging things out for themselves. ... we have tried to leave the reader with something tangible – what a certain number of calories, roentgens, etc., means in terms of an effect on the human being. ... we must think of the people we are writing for.’

‘During World War II many large cities in England, Germany, and Japan were subjected to terrific attacks by high-explosive and incendiary bombs. Yet, when proper steps had been taken for the protection of the civilian population and for the restoration of services after the bombing, there was little, if any, evidence of panic. It is the purpose of this book to state the facts concerning the atomic bomb, and to make an objective, scientific analysis of these facts. It is hoped that as a result, although it may not be feasible completely to allay fear, it will at least be possible to avoid panic.’
‘The consequences of a multiweapon nuclear attack would certainly be grave ... Nevertheless, recovery should be possible if plans exist and are carried out to restore social order and to mitigate the economic disruption.’
‘Suppose the bomb dropped on Hiroshima had been 1,000 times as powerful ... It could not have killed 1,000 times as many people, but at most the entire population of Hiroshima ... [regarding the hype about various nuclear "overkill" exaggerations] there is enough water in the oceans to drown everyone ten times.’
In 1996, half a century after the nuclear detonations, data on cancers from the Hiroshima and Nagasaki survivors was published by D. A. Pierce et al. of the Radiation Effects Research Foundation, RERF (Radiation Research vol. 146 pp. 1-27; Science vol. 272, pp. 632-3) for 86,572 survivors, of whom 60% had received bomb doses of over 5 mSv (or 500 millirem in old units) suffering 4,741 cancers of which only 420 were due to radiation, consisting of 85 leukemias and 335 solid cancers.
‘Today we have a population of 2,383 [radium dial painter] cases for whom we have reliable body content measurements. . . . All 64 bone sarcoma [cancer] cases occurred in the 264 cases with more than 10 Gy [1,000 rads], while no sarcomas appeared in the 2,119 radium cases with less than 10 Gy.’
‘... it is important to note that, given the effects of a few seconds of irradiation at Hiroshima and Nagasaki in 1945, a threshold near 200 mSv may be expected for leukemia and some solid tumors. [Sources: UNSCEAR, Sources and Effects of Ionizing Radiation, New York, 1994; W. F. Heidenreich, et al., Radiat. Environ. Biophys., vol. 36 (1999), p. 205; and B. L. Cohen, Radiat. Res., vol. 149 (1998), p. 525.] For a protracted lifetime natural exposure, a threshold may be set at a level of several thousand millisieverts for malignancies, of 10 grays for radium-226 in bones, and probably about 1.5-2.0 Gy for lung cancer after x-ray and gamma irradiation. [Sources: G. Jaikrishan, et al., Radiation Research, vol. 152 (1999), p. S149 (for natural exposure); R. D. Evans, Health Physics, vol. 27 (1974), p. 497 (for radium-226); H. H. Rossi and M. Zaider, Radiat. Environ. Biophys., vol. 36 (1997), p. 85 (for radiogenic lung cancer).] The hormetic effects, such as a decreased cancer incidence at low doses and increased longevity, may be used as a guide for estimating practical thresholds and for setting standards. ...

‘[Due to the Chernobyl nuclear accident in 1986] as of 1998 (according to UNSCEAR), a total of 1,791 thyroid cancers in children had been registered. About 93% of the youngsters have a prospect of full recovery. [Source: C. R. Moir and R. L. Telander, Seminars in Pediatric Surgery, vol. 3 (1994), p. 182.] ... The highest average thyroid doses in children (177 mGy) were accumulated in the Gomel region of Belarus. The highest incidence of thyroid cancer (17.9 cases per 100,000 children) occurred there in 1995, which means that the rate had increased by a factor of about 25 since 1987.
‘This rate increase was probably a result of improved screening [not radiation!]. Even then, the incidence rate for occult thyroid cancers was still a thousand times lower than it was for occult thyroid cancers in nonexposed populations (in the US, for example, the rate is 13,000 per 100,000 persons, and in Finland it is 35,600 per 100,000 persons). Thus, given the prospect of improved diagnostics, there is an enormous potential for detecting yet more [fictitious] "excess" thyroid cancers. In a study in the US that was performed during the period of active screening in 1974-79, it was determined that the incidence rate of malignant and other thyroid nodules was greater by 21-fold than it had been in the pre-1974 period. [Source: Z. Jaworowski, 21st Century Science and Technology, vol. 11 (1998), issue 1, p. 14.]’
‘Professor Edward Lewis used data from four independent populations exposed to radiation to demonstrate that the incidence of leukemia was linearly related to the accumulated dose of radiation. ... Outspoken scientists, including Linus Pauling, used Lewis’s risk estimate to inform the public about the danger of nuclear fallout by estimating the number of leukemia deaths that would be caused by the test detonations. In May of 1957 Lewis’s analysis of the radiation-induced human leukemia data was published as a lead article in Science magazine. In June he presented it before the Joint Committee on Atomic Energy of the US Congress.’ – Abstract of thesis by Jennifer Caron, Edward Lewis and Radioactive Fallout: the Impact of Caltech Biologists Over Nuclear Weapons Testing in the 1950s and 60s, Caltech, January 2003.
Dr John F. Loutit of the Medical Research Council, Harwell, England, in 1962 wrote a book called Irradiation of Mice and Men (University of Chicago Press, Chicago and London), discrediting the pseudo-science from geneticist Edward Lewis on pages 61, and 78-79:
‘... Mole [R. H. Mole, Brit. J. Radiol., v32, p497, 1959] gave different groups of mice an integrated total of 1,000 r of X-rays over a period of 4 weeks. But the dose-rate - and therefore the radiation-free time between fractions - was varied from 81 r/hour intermittently to 1.3 r/hour continuously. The incidence of leukemia varied from 40 per cent (within 15 months of the start of irradiation) in the first group to 5 per cent in the last compared with 2 per cent incidence in irradiated controls. …
‘What Lewis did, and which I have not copied, was to include in his table another group - spontaneous incidence of leukemia (Brooklyn, N.Y.) - who are taken to have received only natural background radiation throughout life at the very low dose-rate of 0.1-0.2 rad per year: the best estimate is listed as 2 x 10-6 like the others in the table. But the value of 2 x 10-6 was not calculated from the data as for the other groups; it was merely adopted. By its adoption and multiplication with the average age in years of Brooklyners - 33.7 years and radiation dose per year of 0.1-0.2 rad - a mortality rate of 7 to 13 cases per million per year due to background radiation was deduced, or some 10-20 per cent of the observed rate of 65 cases per million per year. ...
‘All these points are very much against the basic hypothesis of Lewis of a linear relation of dose to leukemic effect irrespective of time. Unhappily it is not possible to claim for Lewis’s work as others have done, “It is now possible to calculate - within narrow limits - how many deaths from leukemia will result in any population from an increase in fall-out or other source of radiation” [Leading article in Science, vol. 125, p. 963, 1957]. This is just wishful journalese.
‘The burning questions to me are not what are the numbers of leukemia to be expected from atom bombs or radiotherapy, but what is to be expected from natural background .... Furthermore, to obtain estimates of these, I believe it is wrong to go to [1950s inaccurate, dose rate effect ignoring, data from] atom bombs, where the radiations are qualitatively different [i.e., including effects from neutrons] and, more important, the dose-rate outstandingly different.’
‘From the earlier studies of radiation-induced mutations, made with fruitflies [by Nobel Laureate Hermann J. Muller and other geneticists who worked on plants, who falsely hyped their insect and plant data as valid for mammals like humans during the June 1957 U.S. Congressional Hearings on fallout effects], it appeared that the number (or frequency) of mutations in a given population ... is proportional to the total dose ... More recent experiments with mice, however, have shown that these conclusions need to be revised, at least for mammals. [Mammals are biologically closer to humans, in respect to DNA repair mechanisms, than short-lived insects whose life cycles are too small to have forced the evolutionary development of advanced DNA repair mechanisms, unlike mammals that need to survive for decades before reproducing.] When exposed to X-rays or gamma rays, the mutation frequency in these animals has been found to be dependent on the exposure (or dose) rate ...
‘At an exposure rate of 0.009 roentgen per minute [0.54 R/hour], the total mutation frequency in female mice is indistinguishable from the spontaneous frequency. [Emphasis added.] There thus seems to be an exposure-rate threshold below which radiation-induced mutations are absent ... with adult female mice ... a delay of at least seven weeks between exposure to a substantial dose of radiation, either neutrons or gamma rays, and conception causes the mutation frequency in the offspring to drop almost to zero. ... recovery in the female members of the population would bring about a substantial reduction in the 'load' of mutations in subsequent generations.’
George Bernard Shaw cynically explains groupthink brainwashing bias:
‘We cannot help it because we are so constituted that we always believe finally what we wish to believe. The moment we want to believe something, we suddenly see all the arguments for it and become blind to the arguments against it. The moment we want to disbelieve anything we have previously believed, we suddenly discover not only that there is a mass of evidence against, but that this evidence was staring us in the face all the time.’
From the essay titled ‘What is Science?’ by Professor Richard P. Feynman, presented at the fifteenth annual meeting of the National Science Teachers Association, 1966 in New York City, and published in The Physics Teacher, vol. 7, issue 6, 1968, pp. 313-20:
‘... great religions are dissipated by following form without remembering the direct content of the teaching of the great leaders. In the same way, it is possible to follow form and call it science, but that is pseudo-science. In this way, we all suffer from the kind of tyranny we have today in the many institutions that have come under the influence of pseudoscientific advisers.
‘We have many studies in teaching, for example, in which people make observations, make lists, do statistics, and so on, but these do not thereby become established science, established knowledge. They are merely an imitative form of science analogous to the South Sea Islanders’ airfields - radio towers, etc., made out of wood. The islanders expect a great airplane to arrive. They even build wooden airplanes of the same shape as they see in the foreigners' airfields around them, but strangely enough, their wood planes do not fly. The result of this pseudoscientific imitation is to produce experts, which many of you are. ... you teachers, who are really teaching children at the bottom of the heap, can maybe doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.’
Richard P. Feynman, ‘This Unscientific Age’, in The Meaning of It All, Penguin Books, London, 1998, pages 106-9:
‘Now, I say if a man is absolutely honest and wants to protect the populace from the effects of radioactivity, which is what our scientific friends often say they are trying to do, then he should work on the biggest number, not on the smallest number, and he should try to point out that the [natural cosmic] radioactivity which is absorbed by living in the city of Denver is so much more serious [than the smaller doses from nuclear explosions] ... that all the people of Denver ought to move to lower altitudes.'
Feynman is not making a point about low level radiation effects, but about the politics of ignoring the massive natural background radiation dose, while provoking hysteria over much smaller measured fallout pollution radiation doses. Why is the anti-nuclear lobby so concerned about banning nuclear energy - which is not possible even in principle since most of our nuclear radiation is from the sun and from supernova debris contaminating the Earth from the explosion that created the solar system circa 4,540 million years ago - when they could cause much bigger radiation dose reductions to the population by concentrating on the bigger radiation source, natural background radiation. It is possible to shield natural background radiation by the air, e.g. by moving the population of high altitude cities to lower altitudes where there is more air between the people and outer space, or banning the use of high-altitude jet aircraft. The anti-nuclear lobby, as Feynman stated back in the 1960s, didn't crusade to reduce the bigger dose from background radiation. Instead they chose to argue against the much smaller doses from fallout pollution. Feynman's argument is still today falsely interpreted as a political statement, when it is actually exposing pseudo-science and countering political propaganda. It is still ignored by the media. It has been pointed out by Senator Hickenlooper on page 1060 of the May-June 1957 U.S. Congressional Hearings before the Special Subcommittee on Radiation of the Joint Committee on Atomic Energy, The Nature of Radioactive Fallout and Its Effects on Man:
‘I presume all of us would earnestly hope that we never had to test atomic weapons ... but by the same token I presume that we want to save thousands of lives in this country every year and we could just abolish the manufacture of [road accident causing] automobiles ...’
Dihydrogen monoxide is a potentially very dangerous chemical containing hydrogen and oxygen which has caused numerous severe burns by scalding and deaths by drowning, contributes to the greenhouse effect, accelerates corrosion and rusting of many metals, and contributes to the erosion of our natural landscape: 'Dihydrogen monoxide (DHMO) is colorless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death.'
Protein P53, discovered only in 1979, is encoded by gene TP53, which occurs on human chromosome 17. P53 also occurs in other mammals including mice, rats and dogs. P53 is one of the proteins which continually repairs breaks in DNA, which easily breaks at body temperature: the DNA in each cell of the human body suffers at least two single strand breaks every second, and one double strand (i.e. complete double helix) DNA break occurs at least once every 2 hours (5% of radiation-induced DNA breaks are double strand breaks, while 0.007% of spontaneous DNA breaks at body temperature are double strand breaks)! Cancer occurs when several breaks in DNA happen to occur by chance at nearly the same time, giving several loose strand ends at once, which repair proteins like P53 then repair incorrectly, causing a mutation which can be proliferated somatically. This cannot occur when only one break occurs, because only two loose ends are produced, and P53 will reattach them correctly. But if low-LET ionising radiation levels are increased to a certain extent, causing more single strand breaks, P53 works faster and is able deal with faster breaks as they occur, so that multiple broken strand ends do not arise. This prevents DNA strands being repaired incorrectly, and prevents cancer - a result of mutation caused by faults in DNA - from arising. Too much radiation of course overloads the P53 repair mechanism, and then it cannot repair breaks as they occur, so multiple breaks begin to appear and loose ends of DNA are wrongly connected by P53, causing an increased cancer risk.
1. DNA-damaging free radicals are equivalent to a source of sparks which is always present naturally.
2. Cancer is equivalent the fire you get if the sparks are allowed to ignite the gasoline, i.e. if the free radicals are allowed to damage DNA without the damage being repaired.
3. Protein P53 is equivalent to a fire suppression system which is constantly damping out the sparks, or repairing the damaged DNA so that cancer doesn’t occur.
In this way of thinking, the ‘cause’ of cancer will be down to a failure of a DNA repairing enzyme like protein P53 to repair the damage.
'For the mindset that engendered and enables this situation, which jeopardizes the existence of the United States as a nation as well as the lives of millions of its citizens, some American physicians and certain prestigious medical organizations bear a heavy responsibility.
Charles J. Hitch and Roland B. McKean of the RAND Corporation in their 1960 book The Economics of Defense in the Nuclear Age, Harvard University Press, Massachusetts, pp. 310-57:
‘With each side possessing only a small striking force, a small amount of cheating would give one side dominance over the other, and the incentive to cheat and prepare a preventative attack would be strong ... With each side possessing, say, several thousand missiles, a vast amount of cheating would be necessary to give one side the ability to wipe out the other’s striking capability. ... the more extensive a disarmament agreement is, the smaller the force that a violator would have to hide in order to achieve complete domination. Most obviously, “the abolition of the weapons necessary in a general or ‘unlimited’ war” would offer the most insuperable obstacles to an inspection plan, since the violator could gain an overwhelming advantage from the concealment of even a few weapons.’
Disarmament after World War I caused the following problem which led to World War II (reported by Winston S. Churchill in the London Daily Express newspaper of November 1, 1934):
‘Germany is arming secretly, illegally and rapidly. A reign of terror exists in Germany to keep secret the feverish and terrible preparations they are making.’
British Prime Minister Thatcher's address to the United Nations General Assembly on disarmament on 23 June 1982, where she pointed out that in the years since the nuclear attacks on Hiroshima and Nagasaki, 10 million people had been killed by 140 non-nuclear conflicts:
‘The fundamental risk to peace is not the existence of weapons of particular types. It is the disposition on the part of some states to impose change on others by resorting to force against other nations ... Aggressors do not start wars because an adversary has built up his own strength. They start wars because they believe they can gain more by going to war than by remaining at peace.’
J. D. Culshaw, the then Director of the U.K. Home Office Scientific Advisory Branch, stated in his article in the Scientific Advisory Branch journal Fission Fragments, September 1972 (issue No. 19), classified 'Restricted':
'Apart from those who don't want to know or can't be bothered, there seem to be three major schools of thought about the nature of a possible Third World War ...
* 'The first group think of something like World War II but a little worse ...
* '... the second of World War II but very much worse ...
* 'and the third group think in terms of a catastrophe ...
'When the Armageddon concept is in favour, the suggestion that such problems exist leads to "way out" research on these phenomena, and it is sufficient to mention a new catastrophic threat [e.g., 10 years later this was done by Sagan with "nuclear winter" hype, which turned out to be fake because modern concrete cities can't produce firestorms like 1940s wooden-built areas of Hamburg, Dresden and Hiroshima] to stimulate research into the possibilities of it arising. The underlying appeal of this concept is that if one could show that the execution of all out nuclear, biological or chemical warfare would precipitate the end of the world, no one but a mad man would be prepared to initiate such a war. [However, as history proves, plenty of mad men end up gaining power and leading countries into wars.]'
J. K. S. Clayton, then Director of the U.K. Home Office Scientific Advisory Branch, stated in his introduction, entitled The Challenge - Why Home Defence?, to the 1977 Home Office Scientific Advisory Branch Training Manual for Scientific Advisers:
'Since 1945 we have had nine wars - in Korea, Malaysia and Vietnam, between China and India, China and Russia, India and Pakistan and between the Arabs and Israelis on three occasions. We have had confrontations between East and West over Berlin, Formosa and Cuba. There have been civil wars or rebellions in no less than eleven countries and invasions or threatened invasions of another five. Whilst it is not suggested that all these incidents could have resulted in major wars, they do indicate the aptitude of mankind to resort to a forceful solution of its problems, sometimes with success. ...'
It is estimated that Mongol invaders exterminated 35 million Chinese between 1311-40, without modern weapons. Communist Chinese killed 26.3 million dissenters between 1949 and May 1965, according to detailed data compiled by the Russians on 7 April 1969. The Soviet communist dictatorship killed 40 million dissenters, mainly owners of small farms, between 1917-59. Conventional (non-nuclear) air raids on Japan killed 600,000 during World War II. The single incendiary air raid on Tokyo on 10 March 1945 killed 140,000 people (more than the total for nuclear bombs on Hiroshima and Nagasaki combined) at much less than the $2 billion expense of the Hiroshima and Nagasaki nuclear bombs! Non-nuclear air raids on Germany during World War II killed 593,000 civilians. The argument that the enemy will continue stocking megaton fallout weapons if we go to cleaner weapons is irrelevant for deterrence, since we're not planning to start war, just to credibly deter invasions. You should not try to lower your standards of warfare to those of your enemy to appease groupthink taboos, or you will end up like Britain's leaders in the 1930s, trying to collaborate with fascists for popular applause.
Lord Hailsham of Saint Marylebone: ‘My Lords, if we are going into the question of lethality of weapons and seek thereby to isolate the nuclear as distinct from the so-called conventional range, is there not a danger that the public may think that Vimy, Passchendaele and Dresden were all right—sort of tea parties—and that nuclear war is something which in itself is unacceptable?’
Lord Trefgarne: ‘My Lords, the policy of making Europe, or the rest of the world, safe for conventional war is not one that I support.’
Mr. Bill Walker (Tayside, North): ‘I remind the House that more people died at Stalingrad than at Hiroshima or Nagasaki. Yet people talk about fighting a conventional war in Europe as if it were acceptable. One rarely sees demonstrations by the so-called peace movement against a conventional war in Europe, but it could be nothing but ghastly and horrendous. The casualties would certainly exceed those at Stalingrad, and that cannot be acceptable to anyone who wants peace’
On 29 October 1982, Thatcher stated of the Berlin Wall: ‘In every decade since the war the Soviet leaders have been reminded that their pitiless ideology only survives because it is maintained by force. But the day comes when the anger and frustration of the people is so great that force cannot contain it. Then the edifice cracks: the mortar crumbles ... one day, liberty will dawn on the other side of the wall.’
On 22 November 1990, she said: ‘Today, we have a Europe ... where the threat to our security from the overwhelming conventional forces of the Warsaw Pact has been removed; where the Berlin Wall has been torn down and the Cold War is at an end. These immense changes did not come about by chance. They have been achieved by strength and resolution in defence, and by a refusal ever to be intimidated.’
‘... peace cannot be guaranteed absolutely. Nobody can be certain, no matter what policies this or any other Government were to adopt, that the United Kingdom would never again be attacked. Also we cannot tell what form such an attack might take. Current strategic thinking suggests that if war were to break out it would start with a period of conventional hostilities of uncertain duration which might or might not escalate to nuclear conflict. ... while nuclear weapons exist there must always be a chance, however small, that they will be used against us [like gas bombs in World War II]. ... as a consequence of war between other nations in which we were not involved fall out from nuclear explosions could fall on a neutral Britain. ... conventional war is not the soft option that is sometimes suggested. It is also too easily forgotten that in World War II some 50 million people died and that conventional weapons have gone on killing people ever since 1945 without respite.’ - - The Minister of State, Scottish Office (Lord Gray of Contin), House of Lords debate on Civil Defence (General Local Authority Functions) Regulations, Hansard, vol. 444, cc. 523-49, 1 November 1983.

‘It seems that similarities do exist between the processes of formation of single particles from nuclear explosions and formation of the solar system from the debris of a [4 x 1028 megatons of TNT equivalent, type Ia] supernova explosion. We may be able to learn much more about the origin of the earth, by further investigating the process of radioactive fallout from the nuclear weapons tests.’ – Dr Paul K. Kuroda (1917-2001), University of Arkansas, ‘Radioactive Fallout in Astronomical Settings: Plutonium-244 in the Early Environment of the Solar System,’ pages 83-96 of Radionuclides in the Environment: A Symposium Sponsored By the Division of Nuclear Chemistry and Technology At the 155th Meeting of the American Chemical Society, San Francisco, California, April 1-3, 1968, edited by Symposium Chairman Dr Edward C.

Dr Paul K. Kuroda (1917-2001) in 1956 correctly predicted the existence of water-moderated natural nuclear reactors in flooded uranium ore seams, which were discovered in 1972 by French physicist Francis Perrin in three ore deposits at Oklo in Gabon, where sixteen sites operated as natural nuclear reactors with self-sustaining nuclear fission 2,000 million years ago, each lasting several hundred thousand years, averaging 100 kW. The radioactive waste they generated remained in situ for a period of 2,000,000,000 years without escaping. They were discovered during investigations into why the U-235 content of the uranium in the ore was only 0.7171% instead of the normal 0.7202%. Some of the ore, in the middle of the natural reactors, had a U-235 isotopic abundance of just 0.440%. Kuroda's brilliant paper is entitled, 'On the Nuclear Physical Stability of the Uranium Minerals', published in the Journal of Chemical Physics, vol. 25 (1956), pp. 781–782 and 1295–1296.
A type Ia supernova explosion, always yielding 4 x 1028 megatons of TNT equivalent, results from the critical mass effect of the collapse of a white dwarf as soon as its mass exceeds 1.4 solar masses due to matter falling in from a companion star. The degenerate electron gas in the white dwarf is then no longer able to support the pressure from the weight of gas, which collapses, thereby releasing enough gravitational potential energy as heat and pressure to cause the fusion of carbon and oxygen into heavy elements, creating massive amounts of radioactive nuclides, particularly intensely radioactive nickel-56, but half of all other nuclides (including uranium and heavier) are also produced by the 'R' (rapid) process of successive neutron captures by fusion products in supernovae explosions. Type Ia supernovae occur typically every 400 years in the Milky Way galaxy. On 4 July 1054, Chinese astronomers observed in the sky (without optical instruments) the bright supernova in the constellation Taurus which today is still visible as the Crab Nebula through telescopes. The Crab Nebula debris has a diameter now of 7 light years and is still expanding at 800 miles/second. The supernova debris shock wave triggers star formation when it encounters hydrogen gas in space by compressing it and seeding it with debris; bright stars are observed in the Orion Halo, the 300 light year diameter remains of a supernova. It is estimated that when the solar system was forming 4,540 million years ago, a supernova occurred around 100 light years away, and the heavy radioactive debris shock wave expanded at 1,000 miles/second. Most of the heavy elements including iron, silicon and calcium in the Earth and people are the stable end products of originally radioactive decay chains from the space burst fallout of a 7 x 1026 megatons thermonuclear explosion, created by fusion and successive neutron captures after the implosion of a white dwarf; a supernova explosion.
How would a 1055 megaton hydrogen bomb explosion differ from the big bang? Ignorant answers biased in favour of curved spacetime (ignoring quantum gravity!) abound, such as claims that explosions can’t take place in ‘outer space’ (disagreeing with the facts from nuclear space bursts by Russia and America in 1962, not to mention natural supernova explosions in space!) and that explosions produce sound waves in air by definition! There are indeed major differences in the nuclear reactions between the big bang and a nuclear bomb. But it is helpful to notice the solid physical fact that implosion systems suggest the mechanism of gravitation: in implosion, TNT is well-known to produce an inward force on a bomb core, but Newton's 3rd law says there is an equal and opposite reaction force outward. In fact, you can’t have a radially outward force without an inward reaction force! It’s the rocket principle. The rocket accelerates (with force F = ma) forward by virtue of the recoil from accelerating the exhaust gas (with force F = -ma) in the opposite direction! Nothing massive accelerates without an equal and opposite reaction force. Applying this fact to the measured 6 x 10-10 ms-2 ~ Hc cosmological acceleration of matter radially outward from observers in the universe which was predicted accurately in 1996 and later observationally discovered in 1999 (by Perlmutter, et al.), we find an outward force F = ma and inward reaction force by the 3rd law. The inward force allows quantitative predictions, and is mediated by gravitons, predicting gravitation in a checkable way (unlike string theory, which is just a landscape of 10500 different perturbative theories and so can’t make any falsifiable predictions about gravity). So it seems as if nuclear explosions do indeed provide helpful analogies to natural features of the world, and the mainstream lambda-CDM model of cosmology - with its force-fitted unobserved ad hoc speculative ‘dark energy’ - ignores and sweeps under the rug major quantum gravity effects which increase the physical understanding of particle physics, particularly force unification and the relation of gravitation to the existing electroweak SU(2) x U(1) section of the Standard Model of fundamental forces.
Even Einstein grasped the possibility that general relativity's lambda-CDM model is at best just a classical approximation to quantum field theory, at the end of his life when he wrote to Besso in 1954:
‘I consider it quite possible that physics cannot be based on the [classical differential equation] field principle, i.e., on continuous structures. In that case, nothing remains of my entire castle in the air, [non-quantum] gravitation theory included ...’
‘Science is the organized skepticism in the reliability of expert opinion.’ - Professor Richard P. Feynman (quoted by Professor Lee Smolin, The Trouble with Physics, Houghton-Mifflin, New York, 2006, p. 307).
‘The expression of dissenting views may not seem like much of a threat to a powerful organization, yet sometimes it triggers an amazingly hostile response. The reason is that a single dissenter can puncture an illusion of unanimity. ... Among those suppressed have been the engineers who tried to point out problems with the Challenger space shuttle that caused it to blow up. More fundamentally, suppression is a denial of the open dialogue and debate that are the foundation of a free society. Even worse than the silencing of dissidents is the chilling effect such practices have on others. For every individual who speaks out, numerous others decide to play it safe and keep quiet. More serious than external censorship is the problem of self-censorship.’
— Professor Brian Martin, University of Wollongong, 'Stamping Out Dissent', Newsweek, 26 April 1993, pp. 49-50
In 1896, Sir James Mackenzie-Davidson asked Wilhelm Röntgen, who discovered X-rays in 1895: ‘What did you think?’ Röntgen replied: ‘I did not think, I investigated.’ The reason? Cathode ray expert J. J. Thomson in 1894 saw glass fluorescence far from a tube, but due to prejudice (expert opinion) he avoided investigating that X-ray evidence! ‘Science is the organized skepticism in the reliability of expert opinion.’ - Richard Feynman, in Lee Smolin, The Trouble with Physics, Houghton-Mifflin, 2006, p. 307.

Mean yield of the 5,192 nuclear warheads and bombs in the deployed Russian nuclear stockpile as of January 2009: 0.317 Mt. Total yield: 1,646 Mt.
Mean yield of the 4,552 nuclear warheads and bombs in the deployed U.S. nuclear stockpile as of January 2007: 0.257 Mt. Total yield: 1,172 Mt.
For diffraction damage where damage areas scale as the two-thirds power of explosive yield, this stockpile's area damage potential can be compared to the 20,000,000 conventional bombs of 100 kg size (2 megatons of TNT equivalent total energy) dropped on Germany during World War II: (Total nuclear bomb blast diffraction damaged ground area)/(Total conventional blast diffraction damaged ground area to Germany during World War II) = [4,552*(0.257 Mt)2/3]/[20,000,000*(0.0000001 Mt)2/3] = 1,840/431 = 4.3. Thus, although the entire U.S. stockpile has a TNT energy equivalent to 586 times that of the 2 megatons of conventional bombs dropped on Germany in World War II, it is only capable of causing 4.3 times as much diffraction type damage area, because any given amount of explosive energy is far more efficient when distributed over many small explosions than in a single large explosion! Large explosions are inefficient because they cause unintended collateral damage, wasting energy off the target area and injuring or damaging unintended targets!
In a controlled sample of 36,500 survivors, 89 people got leukemia over a 40 year period, above the number in the unexposed control group. (Data: Radiation Research, volume 146, 1996, pages 1-27.) Over 40 years, in 36,500 survivors monitored, there were 176 leukemia deaths which is 89 more than the control (unexposed) group got naturally. There were 4,687 other cancer deaths, but that was merely 339 above the number in the control (unexposed) group, so this is statistically a much smaller rise than the leukemia result. Natural leukemia rates, which are very low in any case, were increased by 51% in the irradiated survivors, but other cancers were merely increased by just 7%. Adding all the cancers together, the total was 4,863 cancers (virtually all natural cancer, nothing whatsoever to do with radiation), which is just 428 more than the unexposed control group. Hence, the total increase over the natural cancer rate due to bomb exposure was only 9%, spread over a period of 40 years. There was no increase whatsoever in genetic malformations.
‘If defense is neglected these weapons of attack become effective. They become available and desirable in the eyes of an imperialist dictator, even if his means are limited. Weapons of mass destruction could become equalizers between nations big and small, highly developed and primitive, if defense is neglected. If defense is developed and if it is made available for general prevention of war, weapons of aggression will become less desirable. Thus defense makes war itself less probable. ... One psychological defense mechanism against danger is to forget about it. This attitude is as common as it is disastrous. It may turn a limited danger into a fatal difficulty.’
Advice of Robert Watson-Watt (Chief Scientist on the World War II British Radar Project, defending Britain against enemy attacks): ‘Give them the third best to go on with, the second best comes too late, the best never comes.’
All of this data should have been published to inform public debate on the basis for credible nuclear deterrence of war and civil defense, PREVENTING MILLIONS OF DEATHS SINCE WWII, instead of dDELIBERATELY allowing enemy anti-nuclear and anti-civil defence lying propaganda from Russian supporting evil fascists to fill the public data vacuum, killing millions by allowing civil defence and war deterrence to be dismissed by ignorant "politicians" in the West, so that wars triggered by invasions with mass civilian casualties continue today for no purpose other than to promote terrorist agendas of hate and evil arrogance and lying for war, falsely labelled "arms control and disarmament for peace": "Controlling escalation is really an exercise in deterrence, which means providing effective disincentives to unwanted enemy actions. Contrary to widely endorsed opinion, the use or threat of nuclear weapons in tactical operations seems at least as likely to check [as Hiroshima and Nagasaki] as to promote the expansion of hostilities [providing we're not in a situation of Russian biased arms control and disarmament whereby we've no tactical weapons while the enemy has over 2000 neutron bombs thanks to "peace" propaganda from Russian thugs]." - Bernard Brodie, pvi of Escalation and the nuclear option, RAND Corp memo RM-5444-PR, June 1965.
Update (19 January 2024): Jane Corbin of BBC TV is continuing to publish ill-informed nuclear weapons capabilities nonsense debunked here since 2006 (a summary of some key evidence is linked here), e.g. her 9pm 18 Jan 2024 CND biased propaganda showpiece Nuclear Armageddon: How Close Are We? https://www.bbc.co.uk/iplayer/episode/m001vgq5/nuclear-armageddon-how-close-are-we which claims - from the standpoint of 1980s Greenham Common anti-American CND propaganda - that the world would be safer without nuclear weapons, despite the 1914-18 and 1939-45 trifles that she doesn't even bother to mention, which were only ended with nuclear deterrence. Moreover, she doesn't mention the BBC's Feb 1927 WMD exaggerating broadcast by Noel-Baker which used the false claim that there is no defence against mass destruction by gas bombs to argue for UK disarmament, something that later won him a Nobel Peace Prize and helped ensure the UK had no deterrent against the Nazis until too late to set off WWII (Nobel peace prizes were also awarded to others for lying, too, for instance Norman Angell whose pre-WWI book The Great Illusion helped ensure Britain's 1914 Liberal party Cabinet procrastinated on deciding what to do if Belgium was invaded, and thus failed deter the Kaiser from triggering the First World War!). The whole basis of her show was to edit out any realism whatsoever regarding the topic which is the title of her programme! No surprise there, then. Los Alamos, Livermore and Sandia are currently designing the W93 nuclear warhead for SLBM's to replace the older W76 and W88, and what she should do next time is to address the key issue of what that design should be to deter dictators without risking escalation via collateral damage: "To enhance the flexibility and responsiveness of our nuclear forces as directed in the 2018 NPR, we will pursue two supplemental capabilities to existing U.S. nuclear forces: a low-yield SLBM warhead (W76-2) capability and a modern nuclear sea launched cruise missile (SLCM-N) to address regional deterrence challenges that have resulted from increasing Russian and Chinese nuclear capabilities. These supplemental capabilities are necessary to correct any misperception an adversary can escalate their way to victory, and ensure our ability to provide a strategic deterrent. Russia’s increased reliance on non-treaty accountable strategic and theater nuclear weapons and evolving doctrine of limited first-use in a regional conflict, give evidence of the increased possibility of Russia’s employment of nuclear weapons. ... The NNSA took efforts in 2019 to address a gap identified in the 2018 NPR by converting a small number of W76-1s into the W76-2 low-yield variant. ... In 2019, our weapon modernization programs saw a setback when reliability issues emerged with commercial off-the-shelf non-nuclear components intended for the W88 Alteration 370 program and the B61-12 LEP. ... Finally, another just-in-time program is the W80-4 LEP, which remains in synchronized development with the LRSO delivery system. ... The Nuclear Weapons Council has established a requirement for the W93 ... If deterrence fails, our combat-ready force is prepared now to deliver a decisive response anywhere on the globe ..." - Testimony of Commander Charles Richard, US Strategic Command, to the Senate Committee on Armed Services, 13 Feb 2020. This issue of how to use nuclear weapons safely to deter major provocations that escalate to horrific wars is surely is the key issue humanity should be concerned with, not the CND time-machine of returning to a non-nuclear 1914 or 1939! Corbin doesn't address it; she uses debunked old propaganda tactics to avoid the real issues and the key facts.
For example, Corbin quotes only half a sentence by Kennedy in his TV speech of 22 October 1962: "it shall be the policy of this nation to regard any nuclear missile launched from Cuba against any nation in the Western hemisphere as an attack by the Soviet Union on the United States", and omits the second half of the sentence, which concludes: "requiring a full retalitory response upon the Soviet Union." Kennedy was clearly using US nuclear superiority in 1962 to deter Khrushchev from allowing the Castro regime to start any nuclear war with America! By chopping up Kennedy's sentence, Corbin juggles the true facts of history to meet the CND agenda of "disarm or be annihilated." Another trick is her decision to uncritically interview CND biased anti-civil defense fanatics like the man (Professor Freedman) who got Bill Massey of the Sunday Express to water down my article debunking pro-war CND type "anti-nuclear" propaganda lies on civil defense in 1995! Massey reported to me that Freedman claimed civil defense is no use against a H-bomb, which he claims is cheaper than dirt cheap shelters, exactly what Freedman wrote in his deceptive letter published in the 26 March 1980 Times newspaper: "for far less expenditure the enemy could make a mockery of all this by increasing the number of attacking weapons", which completely ignores the Russian dual-use concept of simply adding blast doors to metro tubes and underground car parks, etc. In any case, civil defense makes deterrence credible as even the most hard left wingers like Duncan Campbell acknowledged on page 5 of War Plan UK (Paladin Books, London, 1983): "Civil defence ... is a means, if need be, of putting that deterrence policy, for those who believe in it, into practical effect."
Above: Lying CND propaganda postcard on the neutron bomb issued by Yorkshire Region CND (campaign for nuclear disarmament). The back of the postcard falsely claims: 'Civilians, rather than easily protected tanks, will be the main targets.' You can't easily protect a tank from hundreds of thousands of rads of extremely high energy (14.1 MeV) fusion neutrons, which is the whole point of the neutron bomb. The well-known good absorbers for low energy neutrons in a nuclear reactor (cadmium and boron) are relatively ineffective at capturing such high energy neutrons, and if you use heavy metals to scatter and slow down the high energy neutrons, like steel or depleted uranium, you get gamma rays given off when the neutrons deposit energy in the nuclei they strike. So then you have a secondary radiation hazard, not to mention the immense weight increase to the tank which would have major implications (tanks are normally extremely heavy and a massive increase in armour would have severely detrimental effects, such as bogging them down more easily, increasing fuel consumption and decreasing speed). If civilians (not in tanks) were the targets, you wouldn't need to use short-range radiation effects because you could just use blast and fallout against them, but they weren't the targets. As the lying CND propagandarists knew, the deterrent targets were the Warsaw Pact communist tanks which outnumbered those on the West by three-to-one:

Dolan's originally secret manual Capabilities of Nuclear Weapons, DNA-EM-1, U.S. Department of Defense, Chapter 5, Nuclear Radiation Phenomena, August 1981 revision. According to the Medical NBC Battlebook, USACHPPM Tech Guide 244, May 2000, page 2-18, a 3 kt enhanced neutron weapon with a fission yield of 50% (i.e. 5% of yield as residual radiation, which is a trivial effect for the burst height of the neutron bomb) will release 30% of its energy as blast (trivial for the 720 metres height of burst for tactical use of a 3 kt neutron bomb), 20% as thermal radiation (again, relatively trivial even near ground zero, due to yield and burst altitude), and 45% as inital nuclear radiation. These ratios will be altered for other fission yields. At very low yields, there is a problem with using a small fission primary to ignite the fusion stage in a Teller-Ulam device because the fraction of yield released as X-rays by a very low yield fission device is small (it depends strongly on the yield to mass ratio of the primary stage), thus the fusion stage ignition-efficiency due to X-ray ablation induced recoil falls. Most of the energy from a low yield primary stage is in a relatively slow moving (compared to light-velocity X-rays) debris hydrodynamic shock wave, that delivers energy to the fusion stage slowly and without efficient focussing. Fortunately, the neutron bomb is not concerned with maximising Teller-Ulam efficiency, but with producing a small yield with a maximised neutron output!

Dolan's originally secret manual Capabilities of Nuclear Weapons, DNA-EM-1, U.S. Department of Defense, Chapter 5, Nuclear Radiation Phenomena, August 1981 revision (the simple geometric inverse square law of divergence of neutrons from a point source isn't included in the shielding curves above). Notice that over small distances in the air, the neutron fluence is higher than in a vacuum, because there is little attenuation by air over a short distance, but you get an additional large neutron dose from neutrons being scattered back at you which have gone past (and also through) you, and have then been scattered back at you, by large number of nuclei which are obviously located at greater distances (beyond your distance from the detonation!). This is also why tanks can't be protected with a relatively light weight shield on top of the crew compartment, as we shall see later on: it is not possible to protect tanks existing against neutron radiation without adding so much mass the turret would be retarded and the performance of the tank would be crippled. A tank designed to properly protect its crew against 14.1 MeV neutron bomb neutrons and with a big enough engine to perform reasonably well, would be so heavy it would be swallowed up by the earth and simply disappear into soft ground, being rendered useless (the shielding of 14.1 MeV neutrons has nothing to do - either in mechanism or in amount of shielding - with the easy-to-shield thermalized 0.025 eV neutrons by cadmium control rods in a nuclear reactor).

The Pope did help defeat communists.
Motl wouldn't be allowed to write what he wanted on his blog if it wasn't for people like the Pope fighting the commies.
The Pope supported peace and awarded the neutron bomb inventor Cohen for deterring the 3-to-1 Warsaw Pact tank superiority in England.
Dear N,
I am still grateful to John Paul II for various things, but the communism in Czechoslovakia was primarily defeated by the Czechoslovak students like me and those who followed. It is not quite clear to me what mechanism are you imagining in Pope's victory over communism, except for his prayers.

Dear Lubos,
The mechanism: in 1979 the communist power was at its highest, they had achieved nuclear parity with the West and they invaded Afghanistan.
The Pope - unlike predecessors - took a strong line against it. Giving Cohen a medal for peace is not the mechanism I mean. Reagan deployed the neutron bomb in Western Europe.
The Warsaw Pact was already under enormous financial burdens.
Capitalism defeated communism by outspending on arms to deter them. This required the moral backing of the Pope, who was from Poland (which is probably more grateful than Czech Republic). Reagan sparked off the need for economic reform not only with neutron bombs but by "starwars" etc.
This means that they gave up trying to win the Cold War, and Gorbachev came to power to reform the commie economy and try to make consumer goods and sort out food shortages.
As soon as Gorbachev relaxed state police power in the Warsaw Pact, communism was able to collapse.
If the background situation was not relaxed as a result of the Pope and others condemning communism and supporting the arms race against it, it could have won.
Student protests are not going to be effective unless the regime is demoralized and relaxing its iron grip first as shown by the earlier failure in Prague, Czechoslovakia in 1968 and in other states where students were simply driven over by tanks or guns. (Hungary 1956, Tiananmen Square, China 1989.)
It was only because the Pope and Reagan had used the arms race to force economic reform on Gorbachev that you Czech students did not have to face the tanks of the Red Army.

Hi Kea,
Lubos Motl is right about the climate change manure because what the doom-sayers of climate change forget is that we're running out of fossile fuels anyhow!
Before the world is wrecked completely by global warming, we'll have run out of oil, coal, gas (North Sea oil is far more expensive than Arabic supplies because of the costs of oil rigs in the North Sea, and gas - "vapour" I suppose to USA readers to avoid confusion with gas(oline) - is seriously more expensive now that the market is opened up to Europe by a new gas pipeline, and if I buy a new home I'm getting all-electric heating, not the traditional piped gas heating currently used in most of the UK).
To combat global warming, go nuclear. Nuclear is clean, safe, and it is EVEN ECONOMICAL if you lower radioactive pollution horseshit propaganda and shoot crackpots who claim radiation is lethal.
Those people don't understand background radiation, or the effect of higher altitudes, air travel, etc on radiation exposure.
They think "natural" radiation is safe and "artificial" radiation from nuclear power is totally different.
The Health Physicists who work in the nuclear industry are a load of gormless, feeble, patronising fools who couldn't explain anything to anybody without making it sound like condescending pro-nuclear propaganda, which is why the situation continues.
They have no idea that physics and maths are well known, and that people can by and large understand radiation. They perpetuate the myths.
The FIRST thing physicists in the f***ing nuclear industry should put on their posters is the fact that on the Moon the natural radiation is 50 times higher than on earth, 1 mR/hr on Moon compared to 0.02 mR/hr on Earth (the earth's atomsphere shields most of the background radiation, which is 99% protons and alpha particles).
Then they should give the ACTUAL (not relative!) natural dose rates in different cities with different bedrocks and altitudes above sea level! The thorium rich beach sands of Brazil and India are more radioactive than 90% of the "nuclear waste" from the nuclear industry!
It is a wide range!!! Then, finally, they should show the lies about low level radiation by plotting the mortality in Hiroshima and Nagasaki and other long-term reliable studies as a function of dose.
It is true that massive doses severely increase leukemia rates, but it is a lie that small doese do so in proportion, or that other cancers are increases in the same way. Leukemia is a special problem, because the bone marrow is very susceptible to ionising radiation.
Particularly, high-LET (linear energy transfer) radiations like alpha and beta and also soft x-rays (which cause ionisation by the photoelectric effect) inside the body increase cancer risks, NOT low-LET radiation like gamma rays (unless the dose is really massive).
People should be aware that the more penetrating the radiation is, the less of it gets stopped by soft tissue in the body, so the LOWER the absorbed dose per unit of fluence!
The real dangers from low level radiation are from ingesting or inhaling soluble alpha and beta emitters, like radium and strontium-90 respectively, which get deposited in bone and can cause leukemia. Radon gas from the decay of radium is also a massive natural hazard, killing far more people than all the hundreds of megatons of 1950s nuclear tests or Chernobyl.
Chernobyl showed that iodine-131 causes a short term problem (half like 8 days) after an explosion, because it gets concentrated in milk and then in kid's thyroid glands and can cause lumps (mostly benign). The answer is simple: for the few weeks while milk is contaminated, either put it through an ion-exchanger to remove the iodine-131, or switch to using powdered milk or simply put the cattle in winter barns eating winter feed like hay so that they don't eat contaminated grass! Problem sorted!
See http://glasstone.blogspot.com/2006/04/fallout-prediction-and-common-sense-in.html for more info on this!
Regards Hiroshima and Nagasaki long-term radiation effects cover-up, see links on http://www.rerf.or.jp/top/introe.htm:
Fewer than 1% of victims died due to cancer caused by radiation!!!!!
The maximum leukemia rate occurred in 1952 and ever since has been declining. There were no genetic effects above the normal rate in offspring of even highly irradiated survivors and cancer risks were carefully studied:
'The Life Span Study (LSS) population consists of about 120,000 persons who were selected on the basis of data from the 1950 Japanese National Census. This population includes ... atomic-bomb survivors living in Hiroshima or Nagasaki and nonexposed controls. ... all persons in the Master Sample who were located less than 2,500 meters from the hypocenter ATB were included in the LSS sample, with about 28,000 persons exposed at less than 2,000 meters serving as the core. Equal numbers of persons who had been located 2,500-9,999 meters from hypocenter ... were selected to match the core group by age and sex. ... As of 1995, more than 50% of LSS cohort members are still alive. As of the end of 1990, almost 38,000 deaths have occurred in this group, including about 8,000 cancer deaths among the 87,000 survivors. Approximately 430 of these cancer deaths are estimated to be attributable to radiation.'
More here.
Sorry to go on, but all this environmental crackpottery just drives me nuts.

"By an amazing coincidence, the configuration resembles a peace symbol with Earth at its centre."
Yes, it's the CND symbol, invented in by Gerald Holtom for the march of the Direct Action Committee Against Nuclear War from London to Aldermaston, Easter 1958.
CND was unfortunately debunked as being largely run by Moscow-funded 'World Peace Council' Soviet communists, by Paul Mercer's book, “Peace” of the dead: The Truth Behind the Nuclear Disarmers (London, 1986). The worst thing about the Soviet/CND 'peace offensive' attacking civil defence precautions by making false claims about the effects of nuclear weapons, and also the effect it had on Samuel Cohen's invention of the neutron bomb to stop wars and to stop reliance on high yield nuclear weapons, which can cause collateral damage to civilian areas nearby.
I think it's a good thing to have peace, but there are issues about how best to get there. (Simple disarmament was tried in Britain in the 1920s and 1930s, but it just encouraged enemy aggression.)
Update 15 May 2007: there is an interesting interview of Samuel Cohen by the Wired journalist Charles Platt, "The Profits of Fear", where Platt admits:
"... Journalists were not much better. They could have learned the ethical basis for the neutron bomb easily enough if they cared to do so, but, they didn't care. They took the lazy way out, quoting cheap shots from peace activists' press releases, which never failed to tag the bomb as the "ultimate capitalist weapon." Cohen took grim solace when Leonid Brezhnev denounced him publicly as an "international war criminal," but the vilification he received in his own country was hard to endure.
"Confronted with bad press, venal politicians, and world leaders who still seemed hooked on the drama of weapons that would cause as much destruction as possible, Cohen concluded that neutron bombs would be built only if the United States got itself into a conventional war that imposed an intolerable financial burden while creating unacceptable casualties among American troops. As the years passed, the Vietnam War certainly began to fit this description. "We had close to a half million American casualties in Vietnam," Cohen recalls, "and by this time the Livermore laboratory had put in a proposal to Washington stating that they could manufacture a couple hundred neutron bombs. Of course, no one can predict the number of bombs that would produce any specific result, but I believe that considerably less than 200 neutron bombs could have ended that war."
"Since an outright retreat from Vietnam seemed unthinkable at this time, the situation invited a quick application of overwhelmingly superior military technology--which could now be achieved without targeting civilians or destroying the infrastructure that sustained them. Once again, however, Cohen found himself thwarted by theories and prejudices that made this unacceptable. The neutron bomb was still nuclear, the Vietnamese were Asian, yet even this wasn't the biggest issue. According to conventional wisdom, any small nuclear weapon was dangerous because the nation that used it would encourage other nations to use theirs, and a back-yard nuclear squabble would escalate to a full-scale nuclear war.
"This was like the theory that anyone who used marijuana would wind up using heroin. No evidence existed to support it. No national leader had ever threatened to respond with a big nuke if someone else launched a small one. Still, everyone was afraid that it could happen, and Cohen couldn't prove that it wouldn't."

Is there exist limit on size of H-bomb?From Brief story of time:
Such conditions could occur in a very big hydrogen bomb: the
physicist John Wheeler once calculated that if one took all the heavy water in all the oceans of the world, one could
build a hydrogen bomb that would compress matter at the center so much that a black hole would be created. (Of
course, there would be no one left to observe it!).So what type of tamper he consider ?Mass of uranium on Earth not enough to compress ~4.8*10^13 tons of deuterium.How many stages this would be? Its evidence that multi-stage designs have far better yield-to weight ratio than smaller ones.Another side: George Dyson when he described USAF Doomsday Orion proposal in BBC doku:To mars by A-bomb says that its bomb (1650 metric tons) largest physically possible.What this mean?Probably this bomb would have largest physically possible yield-to weight ratio for tn-weapons(~100 megaton per ton)?Idea was to detonate this at very high alltitude (~400km) at Soviet Union,this would spread fires over entire hemisphere and probably destroy ozone layer.Gold is better for compression than uranium?What this fireball would be ,X-ray-fireball ?Probably fireball would be spread over entire hemisphere.
Yes, you can distil deuterium from sea water and in principle use it to make an arbitrarily large explosion. Regarding the problems of using a small fission bomb to compress and ignite the (extremely large) deuterium capsule in such a design, there are two obvious possibilities:
(1) You just make the deuterium capsule a very long cylinder (along its long axis), and put the small fission bomb at one end. The X-rays can't ablate and compress the entire long secondary simultaneously, but they will get the reaction started for the first few feet length near one end of the cylinder. The fusion energy released at that end will be accompanied by X-rays, which will ablate and compress the next few feet of the length of the deuterium cylinder's metal pusher, and so on, like the burning of a fuse. The efficiency will be expected to increase as more and more deuterium is fused.
(2) Another obvious possibility is a "Russian doll" design. Here you have only one fission stage, but you have lots of cases of increasing sizes with increasingly sized separate deuterium stage capsules in each case, all within one another. So you start with a normal two stage Teller-Ulam thermonuclear bomb with just a normal megaton or whatever sized fusion secondary, complete with outer casing. Then you take that entire bomb (with its case) and use the whole thing exactly like a a "primary" stage, inside another bigger bomb, which also has its own fusion secondary stage and its own outer casing. Then you take that entire "Russian doll" bomb, and use it as the primary stage for still another even bigger bomb, and so on. This way, can start with just the 2 kg or so of fissile material required for a single kiloton fission primary and work up in stages to achieve an effective "primary" as big as you want, without using any more fissile material. All of the secondary stages can just use deuterium (in an ablative casing of depleted uranium, thorium, lead, or whatever).
Herman Kahn discusses these ideas under the category "doomsday machines". However, they are undeliverably heavy, exceedingly expensive (deuterium is very expensive to distil in massive amounts, it's not as free as the sea water which contains it; sea water also contains gold but it's not worth the expense to extract it except as a byproduct of some desalination plant operations), and unpractical for military purposes. Maybe the long-line version (type 1 above) could be useful for economically digging a very long, very big, extremely deep canals, making huge tunnels through massive mountain ranges, and similar geophysical engineering, once the current nuclear hysteria in the media dies down a little. The other design could be used for really huge "orion" type nuclear explosion pulse accelerated spacecraft.
Thanks.
As for histeria-I'm completely shocked not only histeria by media,but "works" by FAS staff (Kristenson) and his comrades in NRDC.
They give initially absurdly small yields
for some US weapons(this was corrected in 2009) ,but 1.1 mt yield for mk28Y1(strategic version)was a yield of clean version,est.yield prior test was 800kt,but this is only 1/5 of full yield.Also numbers,it seems that numbers of mk39-s and mk-41-s were higher than 700 and 500 respectively.Initial plan for mk41s would be as high as number of heavy bombers*2,but in 1960 under pressure of some Joint Chiefs of Staff Eisenhower approved replacements of loadings-prior each bomber carry 2 type B ,after this was a mix of B and D (4 per bomber)+Hound Dogs were deployed ,however only 54 by end of 1960.But ,it seems that number of mk-41s was somewhat larger.
Another ,their's constant false -absurdly exaggeration of effects,totaly using Postol's falsehoods,lying about impossibility of missile defence and etc.They finally claimed that ....... 368 w-88 airbursts required to kill............25% population of China.They against any new weapons and scientific work on its and related technologies,for complete eliminations of nuclear weapons as soon as possible,this would be a mistake.I'm believe that China since 2025 would be a very big problem.
Hi,
What annoys me about NRDL is that they got the 1992 version of Brode's "Capabilities of Nuclear Weapons" declassified under the freedom of information act, as William Arkin reported in the July 1997 Bulletin of Atomic Scientists, and now they are sitting on it, effectively keeping it secret! When will they digitalize it and put it online as a PDF file?
Also, the volume of the NRDL "Nuclear Weapons Databook" on British nuclear weapons is completely wrong. They claimed the first British thermonuclear test Short Granite was not a radiation-coupled separate stage device but a layer cake (a spherical design with lithium deuteride packed around the fission core), when in fact it was a two stage device. The failure to achieve a high yield was due to Taylor instability in the poorly designed secondary stage. This is made crystal clear in the detailed description of the device by the actual designer, reprinted as an appendix to "Britain and the H-Bomb" by the official historians, Lorna Arnold and Katherine Pyne (2001).
Britain’s first hydrogen bomb test, Short Granite, had a fusion stage physically separate from the 30-kt fission stage, but the fusion charge was a spherical layer cake; it had 14 concentric layers 0.86 mm to 2.47 cm thick, alternately lithium-6 deuteride and uranium-238. Dr William Penney designed the first version of this bomb in September 1955, as two spherical units, a fission bomb and a fusion charge, within a single cylindrical bomb casing. Penney’s design only yielded 300-kt when tested on 15 May 1957, because the 14 thin shells of uranium and lithium deuteride were too thin to allow fission and fusion reactions. Where they were mixed up by instabilities during compression, the resulting mixture prevented fusion reactions.
However, this low yield was sorted out by redesigning the spherical secondary (fusion) stage so that it contained a small U-235 core surrounded by just one thick lithium-6 deuteride layer and finished with an outer shell of U-238. This redesign was tested on 8 November containing a 45-kt fission primary with a beryllium reflector and yielded 1.8-Mt.
Lorna Arnold, the official historian of Britain’s nuclear tests, states in the book Britain and the H-Bomb (Palgrave, New York, 2001, p. 160) that in the fission primary the chemical explosive implosion system took 70 microseconds (from electrical detonation time) to achieve maximum compression of the plutonium core. Arnold states that the x-ray energy it released compressed the fusion stage diameter by 2.7 times, thereby increasing its density by 20 times within a time of 2 microseconds. This is to be compared to a maximum density increase of only 8 times in the much smaller fission core. It is interesting that the same bomb materials were rearranged to give another design with the fission and fusion stages placed closer together (almost touching), and this was tested with a yield of 3-Mt on 28 April 1958. This design was only 3.2 metric tons and therefore gave nearly 1-kt/kg. It was manufactured as Yellow Sun Mk1 and was stockpiled by the RAF from 1959-62.
Closer spacing of the two stages therefore increased efficiency and thus the yield of the weapon by 67 %, instead of reducing the yield by causing the shock to upset the fusion stage (as you might expect). The speed of the x-ray mechanism is so much faster than the material shock wave, that the latter can be forgotten in the design process. In the 1950s American thermonuclear weapons, the secondary charges were cylinders, not spheres as used in British weapons. The American W-28 weapon uses a tapering cylinder, which is widest near the fission bomb, but becomes narrower at greater distances to allow for the fact that the x-ray intensity falls with distances so the parts of the fusion stage further from the fission bomb get less compression force. To keep the compression factor constant, the fusion charge cylinder must become narrower with increasing distance from the x-ray source.
After the exchange of American-British research on nuclear weapons in 1959, America developed the W-50 warhead that contained a 410-kt nuclear explosive with a spherical second stage like the British devices. The W-50 nuclear component mass was 186 kg, 1.12 m long and 39 cm in diameter. It was first tested as Aztec on 27 April 1962, and was also used for the high altitude tests that same year, Kingfish and Bluegill. America also used spherical fusion stages in its most recent warheads, the W-87 and W-88 (their blueprint schematics were released after Dr Wen Ho Lee allegedly emailed them to communist China). The W-87 is very similar to the classic British thermonuclear design, with a spherical fission bomb beside a spherical fusion charge containing a U-235 core surrounded by a shell of lithium-6 deuteride, and topped off with a U-238 pusher. The W-88 is somewhat different in that it uses a prolate-spheroid shaped implosion fission bomb, and the fusion charge differs from that in the W-87 because it contains a U-235 pusher instead of U-238.
Sorry, I mean NRDC not NRDL in the comment above!
It seems fo me that Soviet tsar bomb was a not 3-stage device,but a cluster of smaller ones(probably 8*12.5Mt).
Soviet Union never considered this as weapon,one proposal was for using its as mine.They considered 30mt and 50mt for UR-500 and R-56 respectively,however later canceled this.See:Khrushchev, Sergei, Nikita Khrushchev and the Creation of a Superpower, Pennsylvania State University, 2000. I believe this book a best source on soviet weapons and plans to 1965.For later weapons, mostly ICBM warheads i believe reliable data not exist in declassified world.
Hi,
Modern compact MIRVed ICBM warheads like the W87 and W88 have to use spherical/prolate shaped secondaries as is made clear by the unclassified Cox Report on the Wen Ho Lee warhead blueprint leaks.
These spherical shaped secondary stages were first tested in the 1950s by Britain, which declassified the technical details for Arnold's published official history of British research on the H-bomb.
Therefore, there is some information available. Like Dolan's 1972 EM-1, Bridgman makes the point very clearly in his 2001 DTRA book, Introduction to the Physics of Nuclear Weapons Effects that civil defense countermeasures depend on an understanding of the general construction of different kinds of nuclear weapons (pure fission, boosted, gun assembly, and different kinds of thermonuclear weapons like neutron bombs, etc.), because the weapon design determines (1) the output of initial nuclear radiation, which is a key casualty causing agent for low yield weapons once you duck and cover from the thermal flash, blast winds, and flying bebris, (2) EMP (which depends primarily on the prompt gamma output, which depends on the inelastic neutron scatter in the bomb materials, the fission yield, and the bomb outer casing shielding factor), and (3) fallout (neutron induced activities like U237 and Np239 from neutrion capture by U238 greatly affect fallout radiation rates and gamma spectra, so the shielding protection factor during the first few weeks depends critically on bomb design, the kind of tamper or pusher, etc.). Hence the threat from fallout depend on the bomb design; early relatively clean bomb tests in 1956 (Redwing-Navajo and Redwing-Zuni) for example used lead pushers which led to neutron induced lead nuclides in the fallout, while later relatively clean bombs tested in 1958 and later used tungsten pushers, leading to important contributions to fallout radiation by tungsten nuclides due to neutron capture in the tungsten. Tungsten is preferred to lead for use as an ablative pusher because it has nearly double the density of lead and is roughly the density of uranium (specific densities for uranium and tungsten are around 19 grams per cc, compared to only about 11 for lead).
So for real appreciation of civil defense, you need an up to date understanding of bomb design implications for the INR, EMP and fallout effects.
Redwing-Zuni was a clean version of Bassoon device ,its full yield was a 25mt,later deployed as mk-41.
Poplar device was not related to mk-41,its was another device for class B weapon.Its full yield was 20 mt,test yield of clean version was predicted to be a 7mt,in reality-9.3mt.Probably clean version was considered as addition to mk-41,since as its clean version was only 3.5mt.However never deployed.In reality a large number of devices(both 2 and 3-stage) was studied both by LANL and LLNL for new class B warhead (20Mt,10000 pounds).But Bassoon device was a cheapest .And most probably its enlarged version was considered as basis for new Class A weapon(25000 pounds,60Mt).
What would be smallest possible ratio of u-238 casing mass/fusion fuel mass ?And gold as tamper is better than u-238?
You don't need any U-238 in the casing at all. Redwing-Navajo tested at Bikini Lagoon in 1956 had a lead tamper in place of U-238. Total yield 4.5 Mt and fission fraction was 5% or 225 kt, which must have been the yield from full fission of the primary stage. It can't have contained any significant fission "spark plug" in the fusion stage. It still worked fine. Obviously, the heating of the secondary (fusion) stage is reduced by the removal of the fission of a U-238 tamper or pusher around it. So replacing U-238 with lead or tungsten must reduce the efficiency of the fusion reaction, requiring a heavier bomb for the same overall yield.
Ordinary stable gold or Au-197 has a density of 19.32 g/cc, which is similar to uranium.
The neutron capture cross-section for this stable gold Au-197 is only 0.09 barn for 1 MeV fission spectrum neutrons, but seems to drop to about 0.01 barn at 5 MeV and presumably less at higher (fusion neutron) energies, according to Fig 1 in the 1976 translated Russian report http://www-nds.iaea.org/reports-new/indc-reports/indc-ccp/indc-ccp-0082.pdf. I'm not near a library that has the Chemical Rubber Company (CRC) reference work, CRC Handbook of Chemistry and Physics, which is usually the best handy compilation of nuclear data on all the different isotopes, so I can't check that or find out what the neutron inelastic scatter cross-section for gold is. Two 1956 clean (5% and 15% fission) Redwing tests both used lead tampers, while the clean American tests in 1958 and 1962 both used tungsten pushers (tungsten is better than lead, since it has a much higher density).
Gold has the obvious disadvantage of being expensive. Normal tungsten, which is mainly W-184, is much cheaper than gold. Tungsten has of course a very high melting point, 3410.0 °C which is why it is used in light bulb filaments (the melting point is much higher than ordinary silicate soil), so it's neutron capture derivatives behave as super-refractory or "enriched" nuclides in early fallout from surface bursts. However, this doesn't matter for air burst neutron bombs.
It seems that this device that Hawking mentioned and Wheeler studied-largest physically possible Teller-Ulam bomb.Probably Wheeler's goal was to determine upper limit of Teller-Ulam design.
It interesting to estimate its yield,since as deuterium burning would be only first stage ,later helium burning, carbon burning and etc.And other means,such as plasma would be very high-energic.and heavy.
Hi Anonymous,
"It interesting to estimate its yield,since as deuterium burning would be only first stage ,later helium burning, carbon burning and etc.And other means,such as plasma would be very high-energic.and heavy."
Again, please use space after comma or full stop.
Regarding your joke. No, I'm not that stupid. I've read Glasstone's Controlled Thermonuclear Reaction and I know how the sun works - SLOWLY!!!!
Even under the immense compression of the sun's mass and gravity, the nuclear fusion reaction rate per particle is extremely low. This is why it lasts billions of years.
There is no way you are going to burn helium or carbon or anything heavier!
Carbon burning requires the triple alpha process: three helium-4 nuclei have to come together (fusion can't proceed effectively by purely binary processes beyond beryllium, due to a bottleneck in the chain). There is no way you can achieve any efficiency with this process over the timescale of a nuclear explosion.
You're talking about building a new star, a new sun, not a bomb.
True, old heavy stars can explode with a supernova. Betelgeuse, 640 light years away, is supposed to have gone supernova around 1370 AD and its flash is predicted to be seen this year, if they have their sums right.
However, supernovae require immense masses so that a heavy core builds up, creating very heavy elements by successive neutron captures (the R or rapid process), right up to uranium and plutonium. People are never directly going to make exploding star. Maybe eventually there will be robot spacecraft like giant dumper trucks in space that can pile together material to make stars and supernovae, but that's so far off we don't need to worry about it. No terrorist is going to do it in their back room!

Earth 'to get second sun' as supernova turns night into day
By David Gardner
Last updated at 5:53 PM on 22nd January 2011
The Earth could soon have a second sun, at least for a week or two.
The cosmic phenomenon will happen when one of the brightest stars in the night sky explodes into a supernova.
And, according to a report yesterday, the most stunning light show in the planet’s history could happen as soon as this year.
Cosmic phenomenon: The Earth could soon see two suns - just like Luke Skywalker saw on Tatooine in the Star Wars film (pictured)
Earth will undoubtedly have a front row seat when the dying red supergiant star Betelgeuse finally blows itself into oblivion.
The explosion will be so bright that even though the star in the Orion constellation is 640 light-years away, it will still turn night into day and appear like there are two suns in the sky for a few weeks.
The only real debate is over exactly when it will happen.
In stellar terms, Betelgeuse is predicted to crash and burn in the very near future. But that doesn’t necessarily mean you have to rush out and buy sunglasses.
Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland in Australia, claimed yesterday that the galactic blast could happen before 2012 – or any time over the next million years.
‘This old star is running out of fuel in its centre,’ Dr Carter told te Austalian website news.com.au.
‘This fuel keeps Betelgeuse shining and supported. When this fuel runs out the star will literally collapse in upon itself and it will do so very quickly.
‘This is the final hurrah for the star. It goes bang, it explodes, it lights up - we’ll have incredible brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all,’ he added.
Look out: Betelgeuse, which is in the Orion constellation, is set to blow itself into oblivion - which will give the effect of two suns in the sky for us on Earth
The Internet is abuzz with doomsday theories linking the supernova to the Mayan calendar’s prediction of an Armageddon in 2012, fuelled by the association of the word ‘Betelgeuse’ with the devil.
But experts claimed that even if the big bang is looming, it will still happen way too far from Earth to do us any harm.
‘When a star goes bang, the first we will observe of it is a rain of tiny particles called nuetrinos,’ said Dr Carter.
‘They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99% of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever.’
When it happens, the Betelgeuse supernova will almost certainly be the most dramatic ever seen.
It is the ninth brightest star in the night sky and the second brightest in the constellation of Orion, outshining its neighbour Rigel – or Beta Orionis – only very rarely.
It’s distinct orange-red colour makes it easy to spot in the night sky.
If it was at the centre of our solar system, its surface would extend past the asteroid belt, wholly engulfing Mercury, Venus, Mars and the Earth.
There are a couple of minor flaws in the newspaper story just quoted about the forthcoming Betelgeuse supernova. First, it's not proved exactly what the effects will be. Even very weakly interacting particles like neutrinos (misspelled in the article above) can kill you if you get a massive dose. Normally, astronomers see supernovas billions of light years away. This one will be only 640 light years away, that we know for sure. If you do the inverse square law to compare the radiation dose from a supernova 640 light years away to 1,000,000,000 light years away, (1,000,000,000/640)^2 = 2.4 * 10^12. So it's a million million times stronger. The supernova continues radiating radiation at a high rate for days, so it's not just the people on the side facing the initial flash who are exposed.
I'd like to check actual dose estimates, with error limits, before agreeing that we are safe from such a relatively nearby supernova just 640 light years away. People can be protected in principle by the earth's mass, by staying on the opposite side of the earth (in an aircraft flying against the direction of the earth's rotation).
Another thing is the date of the supernova. They can't be sure exactly when it will blow.
Of course neutrinos can't be efficiently shielded by the earth's mass because they are so extremely penetrating, but the light velocity gamma radiation and slower moving charged particle radiation (which will take years to arrive) can be efficiently shielded this way.
It's usually believed that a supernova would need to be within 25 light years of us to kill everyone by muon radiation, but there are various assumptions in the calculations that leave some questions unanswered.
http://www.dailygalaxy.com/my_weblog/2011/01/betelgeuse-could-go-nova-and-become-as-bright-as-a-full-moon.html :
The red giant Betelgeuse, once so large it would reach out to Jupiter's orbit if placed in our own solar system, has shrunk by 15 percent over the past decade in a half, although it's just as bright as it's ever been.
"To see this change is very striking," said retired Berkeley physics professor Charles Townes, who won the 1964 Nobel Prize for inventing the laser. "We will be watching it carefully over the next few years to see if it will keep contracting or will go back up in size."
This is not joke.
In sun pressure only -2.4*10^16 Pa, density- only 150g/cc.
To reach a BH density in this bomb (assuming mass of U-238 tamper -4*10^15 tons)density must be at least ~10^40g/cc,pressure-10^53Pa,T=10^19K or 10^6Gev.Matter would be crushed to pre-quark level. Even in core of neutron star-pressure-10^33 Pa,density-10^14g/cc, T=10^12K or 100 Mev. In 25 solar mass type II supernova silicon burning occurred at density-10^8g/cc, T=2.5*10^9k,with duration of 5 days. Very large stars with mass larger than 260 solar masses directly collapse in black holes and generate 10^54 erg jets. There explosive Si and O burning and far greater pressures than in ordinary supernovas. But in this device density far larger than in above examples, far larger than it needed to burn any element. In certain conditions slow processes would be very fast.
"1.1 Primordial Black Holes
We now have good observational evidence for black holes from stellar masses up to
super-massive holes of 108 to 1010 solar masses and maybe even more. However,
one can also speculate on the possible existence of black holes of much lower mass.
These are the holes for which quantum effects can be important. Such holes could
not form from the collapse of normal baryonic matter because degeneracy pressure
will support white dwarfs or neutron stars below the Chandrasekhar limiting mass.
One can express this limiting mass as mPlanck(mPlanck/mbaryon)2. Its value is about a
solar mass, which might seem a coincidence, but there are good anthropic principle
reasons why stars should be just on the verge of gravitational collapse.
This limiting mass applies only to the formation of black holes through the
gravitational collapse of fermions. In the case of bosons the limiting mass is given
by mPlanck(mPlanck/mboson). To form a black hole by the gravitational collapse of
bosons, they need to have a non-zero mass and either be stable or have a fairly
long life. About the only candidate is the axion, which might have a mass of about
10−5eV. In this case the limiting mass would be about the mass of the Earth,
which is still quite high, and too large for quantum effects to be observable. To
get black holes that are significantly smaller, one could not rely on gravitational
collapse, but would have to shoot matter together with high energies. John Wheeler
once calculated that if one made a hydrogen bomb with all the deuterium from
the oceans, the centre would implode so violently that a little black hole would be
formed. Perhaps fortunately, this experiment is unlikely to be performed. Thus the
only place where tiny black holes might be formed is the early universe."

Even my estimates would be very conservative.
Hi Anonymous,
Hawking produces a lot rubbish based on first-quantization, such as his false claim that black holes should radiate irrespective of their charge.
Black holes are a very convenient hiding ground for egotists who don't want to understand physical mechanism.
Disproof of Hawking's general claim that black holes radiate
Schwinger in 1948 showed that pair production doesn't occur throughout the vacuum of space, but in electric fields >1.3*10^18 volts/metre. This threshold for pair-production is vital for vacuum polarization to stop varying the electronic charge below the IR cutoff in 2nd quantization (QFT), so it destroys Hawking's heuristic explanation for Hawking radiation from uncharged black holes.
The mechanism is that pair production occurs at the event horizon, with one fermion in the pair falling into the black hole, and the other escaping and eventually annihilating with an opposite charge to give a gamma ray (nobody has ever seen this alleged gamma radiation from a black hole, it's conveniently too small to observe above the gamma ray background in space from other sources!).
My argument using Schwinger's 1948 discovery in QFT black holes cannot radiate electrically neutral radiation such as gamma rays. Hawking's heuristic mechanism is false, because you need an electric field above 1.3*10^18 v/m at the event horizon, which means the black hole must be electrically charged in order to radiate anything by Hawking's heuristic mechanism. Things don't happen without a mechanism in QFT.
So uncharged black holes have 0 v/m electric field at their event horizons and emit no gamma rays (Hawking radiation), because there's no pair production there.
If we instead model a fermion as a charged tiny black hole, then it turns out that the electric field strength at its event horizon radius (2GM/c^2) is above the Schwinger's threshold for pair-production, so in this case Hawking's heuristic black hole radiation mechanism (albeit in modified form) does operate: the fermion will radiate charged virtual fermions as radiation, and these virtual fermions will have a charge the same sign as the real fermion in the core (the virtual fermions of sign opposite to thet of the real fermion core will fall into the black hole core). The interesting thing here is that two similar charged fermions travelling in opposite directions cancel one another's magnetic field vectors and thus cancel out the magnetic self-inductance that would otherwise prevent propagation. So massless off-shell (virtual) fermions can be exchanged between similarly charged particles, so that there is an equilibrium of exchange radiation. In this way, you can have charged fermions moving in opposite directions superimposing to create a composite field which is similar to a charged boson. I.e., the opposing half integer spins of each component can add to give bosonic spin.
Hello Nigel!
In fact there not a Brief History of Time was a first mentiotion of this Wheeler's calculation(simulation) This was a :
William J. Kaufmann, "Observing Astronomers: An Interview with Dr. Stephen W. Hawking"; Mercury 4 (November/December, 1975):13-16.
There was before Morland's case ,so he stated simply :Dr. John A. Wheeler estimates that a black hole of mass 10^9 kilograms might be generated artificially by the controlled thermonuclear fusion implosion of approximately 5 x 10^15 kg of deuterium."
Hansen stated that in USSR Teller -Ulam design was known,but this likely that among scientists,Novikov ,of course know this ( he was a Hawking's friend and Zeldovich (a Soviet Wheeler) protege) as Hawking himself.
Its most likely that this was a detailed simulation of such explosion.But mechanism would be more complicated than i'm believed .
10^9 kg-this is probably a uranium sphere in the centre of the bomb.
But what you could say about mechanism?
Mabus.
Sorry,Im mean 5*10^16 kg of deuterium.
You are actually think that in the 1970-s it was impossible to simulate explosion of a such device ?
As ,for SUPER ,from Anne Fitzpatrick Teller’s Technical
nemeses: The American Hydrogen Bomb and Its Development within a Technological
Infrastructure” (TECHNE, Volume 3 No. 3, Society for Philosophy and Technology, Spring 1998),
Part.1.
"The idea for a thermonuclear weapon occurred in 1941 to physicist
Enrico Fermi one afternoon after lunching with Edward Teller in New York,
when the Italian physicist pondered aloud about whether or not an atomic weapon,
which was already in prospect, might be used as a trigger for a deuterium (D)
weapon. In principle, a bomb that fused hydrogen to helium was far more
economical and would produce a much greater explosion than a fission device.
Inspired by Fermi's suggestion, Teller took up the cause of exploring a fusion
weapon (see Rhodes, 1986, and Rhodes, 1995).
Igniting deuterium alone would require temperatures of hundreds of
millions of degrees, so Teller's colleague Emil Konopinski suggested that tritium
(H3) be added to the mixture to lower the ignition temperature. These ideas
became the basis of the "Super" weapon—a fusion bomb that in principle would
create an explosion on the order of megatons.The idea was exceedingly difficult to understand. During the war Teller
and his group attempted to work out the Super theory analytically (by hand), only
to find out it was more complex than anyone, even Teller, had originally
imagined. One major obstacle to the Super appeared in the form of energy
dissipation. The incredible speed of all the reactions inside the deuterium would
make it difficult to deliver the energy needed to reach the ignition point in a short
time. Furthermore, the Inverse Compton Effect would cause cooling of the
hydrogen electrons by collisions with photons coming from the fission initiator."
Mabus.
Part.2. "Hydrogen bomb calculations involve charged particles in addition to
neutrons. Ignition of the Super required heating the material to a critical
temperature rather than assembly of a critical mass (see Metropolis and Nelson,
1982, p. 355). Thus, calculating whether or not the Super could be ignited was a
high hurdle; so was calculating whether or not a cylinder of deuterium, if
ignitable, would be self-propagating and burn. These two aspects constituted what
came to be known at Los Alamos as the "Super Problem."
How could the Super problem be calculated? Enter mathematician John
von Neumann, who had worked at Los Alamos during the war, and was not only
aware of but intrigued by the prospect of a fusion weapon. Von Neumann
arranged to have the Super problem run on ENIAC.
PHIL & TECH 3:3 Spring 1998 Fitzpatrick, Teller's Technical Nemeses/13
Only the first part (ignition) of the Super problem was run on the ENIAC
in 1945 and 1946. The entire calculation was meant to predict the behavior of
deuterium-tritium systems corresponding to various initial temperature
distributions and tritium concentrations. Collectively, the calculations attempted to
predict whether or not a self-sustaining nuclear reaction would occur and ignite a
cylinder of pure deuterium.
The calculations were only one-dimensional. Because of the ENIAC's
memory limits, several effects had to be left out of the problem. Though the Los
Alamos problem was the most complicated of its time, even using 95 percent of
the ENIAC’s control capacity, it did not truly answer the question of whether or
not a Super could be ignited, much less propagate (see Harlow and Metropolis,
1983). Mathematician Stanislaw Ulam once gave his opinion on this calculation:
The magnitude of the problem was staggering. In addition to all
the problems of fission . . . neutronics, thermodynamics,
hydrodynamics, new ones appeared vitally in the thermonuclear
problems: the behavior of more materials, the question of time
scales and interplay of all the geometrical and physical factors. . .
. It was apparent that numerical work had to be undertaken on a
vast scale (quoted in Aspray, 1990, p. 47).
The difficulty of the problem exceeded the technology of the time. Even
Teller, optimistic about the Super's feasibility, realized this and acknowledged
ENIAC’s limitations. Teller recommended that attention be paid to developments
in high-speed electronic calculators; thermonuclear calculations so far indicated
that the complexity of the problems required at least an instrument like the
ENIAC. In 1946, however, there simply were no other large machines available
to Los Alamos besides the ENIAC. The Super problem would have to wait.
Far from Los Alamos, construction of large computers was underway—
slowly, and most would not be ready for several years. Since other new
computers did not seem to be available quickly enough, the Los Alamos
laboratory did not want to wait and began work building its own electronic digital
computer. It was intended to be an exact copy of one that von Neumann was
building at the Institute for Advanced Study (IAS) in Princeton."

Part.3.
"Teller and his colleagues had hoped that either the IAS computer or the
Los Alamos equivalent would be able to carry out a full simulation of the Super
by 1949 or 1950, but construction on both computers fell way behind schedule.
Growing impatient for any electronic machine to be ready, Ulam and University
of Wisconsin mathematician C. J. Everett attempted to solve the ignition part of
the Super problem with slide rules and hand computers, doing simplified
calculations; still, they were not certain if the device would ignite or not, even
though their results looked negative. (See Mark, 1974, and Ulam, 1976.) This
was a problem, then, that weapons scientists felt could not be solved with any
certainty analytically—at least in a reasonable amount of time. Von Neumann
once estimated that completing a hand computation of the Super problem would
require 100 hand computers and 4 years time.
Teller wrote to von Neumann in May, 1950, lamenting that the laboratory
was in a "state of phenomenal ignorance" about the Super. At this time there was
still no machine calculation which had unquestionably proven nor disproven the
feasibility of the Super, and Teller believed that this ignorance was due to the lack
of fast computers. (Personal accounts of some of these difficulties can be seen in
Bethe, 1982, and Los Alamos Historical Society, 1996.)
Teller was disillusioned and depressed by the end of 1950 because his
Super weapon was still not proven either to be workable or not. Moreover, Teller
and his colleagues were under more significant political pressure to at least test a
hydrogen weapon now that the Soviet Union had demonstrated its attainment of an
atomic weapon. At Los Alamos, Ulam produced the first breakthrough to a
workable but very different thermonuclear bomb, which he presented to Teller in
January 1951. Subsequently, Teller and a young protégé, Frederic DeHoffman,
produced a second crucial part of the new thermonuclear configuration. Teller
named this device the "Sausage"—perhaps ironically, as an easier device to
calculate than the Super configuration (see Hewlett and Duncan, 1972).
Collectively, the ideas of Ulam, Teller, and DeHoffman comprised a new
thermonuclear system that appeared viable on paper. It is also more commonly
known as the Teller-Ulam configuration. But even the Sausage would have to be
calculated and tested.
To expedite calculations and to help Los Alamos overcome its shortage of
theoretical help, Teller's friend and colleague, John Archibald Wheeler, had set
PHIL & TECH 3:3 Spring 1998 Fitzpatrick, Teller's Technical Nemeses/15
up his own group at Princeton University to calculate part of the new
thermonuclear configuration, since the laboratory needed as many available
electronic machines as it could get. Wheeler's secret project was code-named
"Matterhorn-B" (B for bomb), and that is where Sausage calculations were done,
and two-dimensional hydrodynamic problems began to indicate the feasibility of
the burning of deuterium in the Sausage.
In the spring of 1952, the Los Alamos computer—the MANIAC
(Mathematical and Numeric Integrator and Calculator; "Gamow" was its
alternative name)—was completed, and it too was instead used for cylindrical
radiation implosion calculations for the Sausage. These hinted at success for the
upcoming Ivy Mike test in November, 1952, which yielded proof of Teller's
fantasy of a multimegaton explosion.
By choosing to develop the radiation implosion Teller-Ulam
configuration, nuclear weapons scientists bypassed the Super problem. The
Teller-Ulam configuration, although itself a difficult model to calculate, was
easier to compute than the Super, a full calculation of which was not done on a
computer until the late 1960s on the Control Data Corporation's 6600 computers."

Theoretical Division leader T. Carson Mark called the “log-jam” in computing.
Weapons scientists were bound by the limits of technology and thus had to adjust
their research program under political pressure—with the limits of the
technological infrastructure in mind."
