How did Truman make a decision to drop the atomic bomb?

Answer 1

Original WRONG Answer:Truman was afraid Germany would use the weapon first.

NO! Germany had surrendered at that point. The allies were fighting the Japanese. The atomic bomb was used to prevent further loss of life. Of course it is logical to question that statement, but understand this: The Japanese based their combat on honor, and it was considered dishonorable to surrender. You may be familiar with kamikazis and similar suicidal tactics. The atomic bomb was used to force the Japanese to surrender becuase an assault on Japan would result in far more casualties for both sides.
