neither Truman nor his advisers resisted the powerful bureaucratic momentum that had accumulated by mid-1945. Truman also decided as he did because he thought that the Japanese—whose most influential military leaders seemed determined to fight on—were "savages, ruthless, merciless, and fanatic." Like many people in 1945, the President was swept up in the passionate emotions of a long and catastrophic war. Finally, Truman felt a considerable responsibility as commander-in-chief. He believed it his duty to put an end to the fighting—especially to American casualties—as soon as possible.
