Le fin mot :
The atomic bombings of Japan occurred three months after the surrender of Germany, whose potential for creating a Nazi a-bomb had led Einstein to push for the development of an a-bomb for the Allies. Einstein withheld public comment on the atomic bombing of Japan until a year afterward. A short article on the front page of the New York Times contained his view: "Prof. Albert Einstein... said that he was sure that President Roosevelt would have forbidden the atomic bombing of Hiroshima had he been alive and that it was probably carried out to end the Pacific war before Russia could participate." ("Einstein Deplores Use of Atom Bomb", New York Times, 8/19/46, pg. 1). Einstein later wrote, "I have always condemned the use of the atomic bomb against Japan." (Otto Nathan & Heinz Norden, editors, "Einstein on Peace", pg. 589).
In November 1954, five months before his death, Einstein summarized his feelings about his role in the creation of the atomic bomb: "I made one great mistake in my life... when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification - the danger that the Germans would make them but there was some justification - the danger that the Germans would make them." (Clark, pg. 752).
