At the State Department, Truman replaced FDR's last secretary of state, Edward Stettinius, with former senator, Supreme Court justice, and war mobilization director James F. Truman inherited Roosevelt's national security team, though he would transform it-in terms of both personnel and organization-during the course of his presidency.

In sum, Truman's foreign policy established some of the basic principles and commitments that marked American foreign policy for the remainder of the twentieth century. Truman intervened with American troops in the conflict between North Korea and South Korea and he supported the creation of the state of Israel in the Middle East. Truman guided the United States through the end of World War II, the beginning of the Cold War between the United States and the Soviet Union, and the dawning of the atomic age.


Truman confronted unprecedented challenges in international affairs during his nearly eight years in office.
