Harry Truman's Leadership

The nation's new chief executive, Harry S Truman, succeeded Franklin D. Roosevelt as president before the end of the war. An unpretentious man who had previously served as Democratic senator from Missouri, then as vice president, Truman initially felt ill prepared to govern. Roosevelt had not discussed complex postwar issues with him, and he had little experience in international affairs. "I'm not big enough for this job," he told a former colleague.

Still, Truman responded quickly to new challenges. Sometimes impulsive on small matters, he proved willing to make hard and carefully considered decisions on large ones. A small sign on his White House desk declared, "The Buck Stops Here." His judgments about how to respond to the Soviet Union ultimately determined the shape of the early Cold War.
