Answer:
President Truman's decision in deploying the atomic bombs on Hiroshima and Nagasaki was partly due to his urgency to end their conflict. As the war went on, it was clear that the Japanese were capable of extreme measures, and prioritized winning as a nation rather than placing value in their lives. Kamikaze planes, and the nature of total warfare signaled at Japan's desperate need of winning the war. With the lives of American soldiers and citizens on the line, Truman made the decision to impair Japan's chances at fighting the war. He didn't really know the true power of the atomic bomb, and part of his decision was based on his curiosity of the functions of the bomb. Little did he know, the bomb's radiation would leave an impact on generations to come, and arguably thickened the tension between the two nations. Some also argue that the attack on Pearl Harbor had played a role in Truman's decision in dropping the atomic bombs on Japan.
