Nuclear weapons are explosive devices that derive their destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter.
- The idea that every nation ought to have an atomic bomb, like every woman of fashion ought to have a mink coat, is deplorable.
- Clement Attlee, cited in S. Beer, Modern British Politics,(Faber and Faber, 1965) and Stuart Thompson,The Dictionary of Labour Quotations, (Biteback Publishing, 2013).
- The American, English and French newspapers are spewing out elegant dissertations on the atomic bomb. We can sum it up in a single phrase: mechanized civilization has just achieved the last degree of savagery...
- Albert Camus, Combat, 8th August 1945. Quoted in In a Dark Time Nicholas Humphrey, Robert Jay Lifton, 1984, (p.27).
- The shields make it so no one bothers with nuclear weapons anymore.
- Be careful above all things not to let go of the atomic weapon until you are sure, and more than sure, that other means of preserving peace are in your hands.
- The atomic bomb is the Second Coming in Wrath.
- Winston Churchill, on hearing about the Trinity test, as recollected in Harvey H. Bundy, "Remembered Words," The Atlantic (March 1957).
- Do not be so naive. With economic conditions the way they are in Russia today, anyone with enough money can buy a nuclear bob. It's no big deal really.
- Vladimir K. Dmitriev, as quoted in Pete Earley, "Comrade J: The Untold Secrets of Russia's Master Spy in America After the End of the Cold War"
- Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of the situation seem to call for watchfulness and, if necessary, quick action on the part of the Administration...
This new phenomenon would also lead to the construction of bombs, and it is conceivable—though much less certain—that extremely powerful bombs of a new type may thus be constructed. A single bomb of this type, carried by boat or exploded in a port, might very well destroy the whole port together with some of the surrounding territory. However, such bombs might very well prove to be too heavy for transportation by air.
- Today the atomic bomb has altered profoundly the nature of the world as we know it, and the human race consequently finds itself in a new habitat to which it must adapt its thinking.
- Albert Einstein, "Only Then Shall We Find Courage", New York Times Magazine (23 June 1946).
- I regard the employment of the atom bomb for the wholesale destruction of men,women and children as the most diabolical use of science.
- Mohandas Gandhi, Harijan, 29 September 1946, quoted in The Making of the Indian Atomic Bomb:Science, Secrecy and the Postcolonial State by Itty Abraham, Zed Books, 1998. (p. 30).
- ...It is only when science asks why, instead of simply describing how, that it becomes more than technology.
When it asks why, it discovers Relativity. When it only shows how, it invents the atomic bomb, and then puts its hands over its eyes and says, "My God what have I done?"
- Ursula Le Guin, "The Stalin in the Soul" in The Language of the Night, 1976.
- Men are the only real monsters. Godzilla's more like a nuclear weapon. A living nuclear weapon destined to walk the Earth forever. Indestructible. A victim of the modern nuclear age.
- I consider your crime worse than murder... I believe your conduct in putting into the hands of the Russians the A-Bomb years before our best scientists predicted Russia would perfect the bomb has already caused, in my opinion, the Communist aggression in Korea, with the resultant casualties exceeding 50,000 and who knows but that millions more of innocent people may pay the price of your treason. Indeed, by your betrayal you undoubtedly have altered the course of history to the disadvantage of our country. No one can say that we do not live in a constant state of tension. We have evidence of your treachery all around us every day for the civilian defense activities throughout the nation are aimed at preparing us for an atom bomb attack.

- I happened to read recently a remark by the American nuclear physicist W. Davidson, who noted that the explosion of one hydrogen bomb releases a greater amount of energy than all the explosions set off by all countries in all wars known in the entire history of mankind. And he, apparently, is right.
- Nikita Khrushchev, Address to the United Nations, New York City (September 18, 1959), as reported by The New York Times (September 19, 1959), p. 8. The physicist quoted was eventually found to be William Davidon, associate physicist at Argonne National Laboratory, Lemont, Illinois.
- We have genuflected before the God of Science only to find that it has given us the atomic bomb, producing fears and anxieties that science can never mitigate.
- Martin Luther King, Strength to Love, 1963.
- The great danger facing us today is not so much the atomic bomb that was created by physical science. Not so much that atomic bomb that you can put in an aeroplane and drop on the heads of hundreds and thousands of people as dangerous as that is. But the real danger confronting civilization today is that atomic bomb which lies in the hearts and souls of men, capable of exploding into the vilest of hate and into the most damaging selfishness—that's the atomic bomb that we've got to fear today. Problem is with the men. Within the heart and the souls of men. That is the real basis of our problem.
- Can one imagine that The Bomb could ever be used "in a good cause"? Do not such means instantly, of themselves, corrupt any cause? The bomb is the natural product of the kind of society we have created. It is as easy, normal, and unforced an expression of the American way of Life as electric ice-boxes, banana splits, and hydro-matic drive automobiles.
- Dwight Macdonald, "Politics" magazine, (August, 1945).
- Any military commander who is honest with himself, or with those he's speaking to, will admit that he has made mistakes in the application of military power. He's killed people unnecessarily—his own troops or other troops—through mistakes, through errors of judgment. A hundred, or thousands, or tens of thousands, maybe even a hundred thousand. But… he hasn't destroyed nations. And the conventional wisdom is don't make the same mistake twice, learn from your mistakes. And we all do. Maybe we make the same mistake three times, but hopefully not four or five. But there will be no learning period with nuclear weapons. You make one mistake and you're going to destroy nations.
- Robert McNamara, in The Fog of War.
- ...if we ourselves happen to survive, are any of us prepared to press the button or allow our elected representatives to command that this be done, in the certainty that it will kill millions of other people?
- It doesn’t even matter if we ever fire these missiles or not. They are having their effect upon us because there is a generation growing up now who cannot see past the final exclamation mark of a mushroom cloud. They are a generation who can see no moral values that do not end in a crackling crater somewhere. I’m not saying that nuclear bombs are at the root of all of it, but I think it is very, very naïve to assume that you can expose the entire population of the world to the threat of being turned to cinders without them starting to act, perhaps, a little oddly.
I believe in some sort of strange fashion that the presence of the atom bomb might almost be forcing a level of human development that wouldn’t have occurred without the presence of the atom bomb. Maybe this degree of terror will force changes in human attitudes that could not have occurred without the presence of these awful, destructive things. Perhaps we are faced with a race between the Four Horseman of the Apocalypse in one line and the 7th Calvary in the other. We have not got an awful lot of mid ground between Utopia and Apocalypse, and if somehow our children ever see the day in which it is announced that we do not have these weapons any more, and that we can no longer destroy ourselves and that we’ve got to do something else to do with our time than they will have the right to throw up their arms, let down their streamers and let forth a resounding cheer.

- Klaatu: It was my intention to discuss this officially—with all the nations of the Earth—but I was not allowed the Opportunity. I have come to realize since that your mutual fears and suspicions are merely the normal reactions of a primitive society.
- We know from scientific observation that you have discovered a rudimentary kind of atomic energy. We also know that you are experimenting with rockets.
- Barnhardt: Yes -- that is true.
- Klaatu: In the hands of a mature civilization, these would not be considered weapons of aggression. But in the hands of your people....

- We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another.
- Interview about the Trinity explosion, first broadcast as part of the television documentary The Decision to Drop the Bomb (1965), produced by Fred Freed, NBC White Paper; Oppenheimer is quoting from the 1944 Prabhavananda and Isherwood translation of the Bhagavad Gita. The line quoted is spoken by Krishna, one of the major avatars of Vishnu; some assert that the passage would be better translated "I am become Time, the destroyer of worlds." · online video at atomicarchive.com
- In plain words; now that Britain has told the world she has the H-Bomb, she should announce as early as possible that she has done with it, that she proposes to reject, in all circumstances, nuclear warfare. This is not pacifism. There is no suggestion here of abandoning the immediate defence of this island.... No, what should be abandoned is the idea of deterrence-by-threat-of-retaliation. There is no real security in it, no decency in it, no faith, hope, nor charity in it.

- The atomic bomb is a marvelous gift that was given to our country by a wise God.
- They asked me what I thought of the atomic bomb. I said I had not been able to take any interest in it.
- Sixteen hours ago an American airplane dropped one bomb on Hiroshima, an important Japanese Army base. That bomb had more power than 20,000 tons of TNT....
With this bomb we have now added a new and revolutionary increase in destruction to supplement the growing power of our armed forces....
It is an atomic bomb. It is a harnessing of the basic power of the universe. The force from which the sun draws its power has been loosed against those who brought war to the Far East....
Having found the bomb we have used it. We have used it against those who attacked us without warning at Pearl Harbor, against those who have starved and beaten and executed American prisoners of war, against those who have abandoned all pretense of obeying international laws of warfare. We have used it in order to shorten the agony of war, in order to save the lives of thousands and thousands of young Americans.
We shall continue to use it until we completely destroy Japan’s power to make war. Only a Japanese surrender will stop us.

Nuclear strategy and policy
- ...the Obama Administration must move more quickly to plan for a future in which nuclear weapons are likely to play a greater role in national defense. Hard as it may be to accept, Dr. Strangelove is back.
- Michael Auslin 
- We will be making a sufficient but necessary contribution if we simply jar the prevalent complacency on the doctrine of shoot-from-the-hip-and-empty-the-magazine.
- We may as well admit that the strictly tactical problem of destroying Manhattan is already absurdly easy, and time promises to make it no less easy. That is only to say that its protection, if it can be protected, is henceforward a strategic and political problem rather than a tactical one.
- The unacceptability of the Doomsday Machine raises awkward, unpleasant, and complicated questions that must be considered by both policy maker and technician. If it is not acceptable to risk the lives of the three billion inhabitants of the earth in order to protect ourselves from surprise attack, then how many people would we be willing to risk? I believe that both the United States and NATO would reluctantly be willing to envisage the possibility of one or two hundred million people (i.e., about five times more than World War II deaths) dying from the immediate effects, even if one does not include deferred long-term effects due to radiation, if an all-out thermonuclear war results from a failure of Type I Deterrence. With somewhat more controversy, similar numbers would apply to Type II Deterrence. (For example, some experts would concede the statement for an all-out Soviet nuclear attack on Europe, but not if the Soviets restricted themselves to the use of conventional weapons.) We are willing to live with the possibility partly because we think of it as a remote possibility. We do not expect either kind of deterrence to fail, and we do not expect the results to be that cataclysmic if deterrence does fail.
- The fact is that nuclear weapons have prevented not only nuclear war but conventional war in Europe for forty years.
