Reply on verso of Godfrey's letter.

"Thank you for sending me your paper on Einstein and me. It is almost wholly correct as to facts. There are only a few small points: the declaration which Einstein and I signed shortly before his death was signed by nine other eminent scientists. Some of the opinions as to how to establish world government belong to the time when America alone had nuclear weapons and are no longer tenable. You speak, in one place, of the "secret". There never was any secret, except for a few small technical details, and the belief that there was served mainly to encourage spy-mania and McCarthyism. What I wrote in 1915 about wars that could be justified is rendered completely obsolete by the invention of nuclear weapons. The human species can no longer be preserved unless all war can be avoided."
