Why did Truman decide to use the nukes

Answer 1

Harry Truman, the President of the United States during World War II, made the decision to use atomic bombs on Japan in order to bring a swift end to the war and avoid a costly and prolonged invasion of the Japanese mainland. The bombings of Hiroshima and Nagasaki were seen as a way to force Japan to surrender and prevent further loss of American and allied lives. The decision was also influenced by the belief that the use of atomic weapons would demonstrate the overwhelming power of the United States and potentially deter future conflicts.
