The Manhattan Project was created when the European conflict began in 1939. In that same year, President Roosevelt was the one who supported the development of these bombs.

However, in 1945, the scene of the war had changed, since the Germans had signed the surrender on May 8, 1945 and peace returned to the European continent. Only in the Pacific did the war continue, and the Japanese refused to lay down their arms. So it was against this people that the American president Truman decided to launch the atomic bombs.
