Harry Truman's justification was that he did it to save the lives of our American soldiers and to end the War between us and the Japanese. He decided to bomb Nagasaki and Hiroshima so that the Japanese would give up. He bombed two giant cities with people who had nothing to do with the war and who were just trying to live instead of hitting the Japanese hard where it hurts, their military. The atomic bomb killed hundreds of thousands of innocent Japanese people instead of attacking their military with people who were ready to die. Japanese attacked our military not our cities with millions of innocent people. Harry Truman had no justification for that.
