Truman's decision to use nuclear weapons to end the War in the Pacific is the subject of much debate. The purpose of this paper is to look at the debate between traditional and revisionist historian views on the subject and gain a better understanding of Truman's decision. The paper shows support for the theory that Truman's decision was appropriate because it was his best available option. It also shows that the Atom bomb actually attacked Japan's center of gravity, the will of the elite Japanese leadership team who administered the war. It did this while at the same time protecting what had become the United States center of gravity by the end of the War-the will of the people of the United States to continue a protracted, costly war.
