“A Third World War? With an atom bomb? He said it, with an atom bomb. There would be no more world. The world would end. Humanity would no longer exist. I think he has to be put in an asylum. He has to be put in an mental asylum.”

“The atomic bomb is too dangerous to be loose in a lawless world.”
Report on the Potsdam Conference (1945)
Context: The atomic bomb is too dangerous to be loose in a lawless world. That is why Great Britain, Canada, and the United States, who have the secret of its production, do not intend to reveal that secret until means have been found to control the bomb so as to protect ourselves and the rest of the world from the danger of total destruction.

“The world will note that the first atomic bomb was dropped on Hiroshima, a military base.”
Report on the Potsdam Conference (1945)
Context: The world will note that the first atomic bomb was dropped on Hiroshima, a military base. That was because we wished in this first attack to avoid, insofar as possible, the killing of civilians. But that attack is only a warning of things to come. If Japan does not surrender, bombs will have to be dropped on her war industries and, unfortunately, thousands of civilian lives will be lost. I urge Japanese civilians to leave industrial cities immediately, and save themselves from destruction.

On his research on atomic nuclei with Ernest Rutherford, p. 24
Portraits in Science interviews (1994)
Context: We were able to discover two new kinds of atomic species, one was hydrogen of mass 3, unknown until that time, and the other helium of mass 3, also unknown. … We were able to show that heavy hydrogen nuclei, that is to say the cores of heavy hydrogen atoms, could be made to react with one another to produce a good deal of energy and new kinds of atom. …Of course, we had no idea whatever that this would one day be applied to make hydrogen bombs. Our curiosity was just curiosity about the structure of the nucleus of the atom, and the discovery of these reactions was purely, as the Americans would put it, coincidental.

“One has to look out for engineers-they begin with sewing machines and end up with the atomic bomb.”

Quoted in "A-bombs were 'God's gifts' to Japanese regime", Taipei Times (August 7, 2005).
