Harry S. Truman never expected to become president.
Until Democratic party leaders chose him to replace Henry Wallace as Roosevelt’s running mate in 1944, he was an undistinguished senator from Missouri who had risen in politics through his connection with the boss of the Kansas City political machine, Tom Pendergast. When he assumed the presidency after Roosevelt’s death in April 1945, Truman found himself forced to decide foreign policy debates in which he had previously played virtually no role.
Convinced that Stalin could not be trusted and that the United States had a responsibility to provide leadership to a world that he tended to view in stark, black-and-white terms, Truman soon determined to put the policy of containment into effect. The immediate occasion for this epochal decision came early in 1947 when Britain informed the United States that because its economy had been shattered by the war, it could no longer afford its traditional international role. Britain had no choice but to end military and financial aid to two crucial governments—Greece, a monarchy threatened by a communist-led rebellion, and Turkey, from which the Soviets were demanding joint control of the straits linking the Black Sea and the Mediterranean. Britain asked the United States to fill the vacuum.
The Soviet Union had little to do with the internal problems of Greece and Turkey, where opposition to corrupt, undemocratic regimes was largely homegrown. Neither had held truly free elections. But they occupied strategically important sites at the gateway to southeastern Europe and the oil-rich Middle East. Truman had been told by Senate leader Arthur Vandenberg that the only way a reluctant public and Congress would support aid to these governments was for the president to “scare hell” out of the American people. To rally popular backing, Truman rolled out the heaviest weapon in his rhetorical arsenal—the defense of freedom. As the leader of the “free world,” the United States must now shoulder the responsibility of supporting “freedom-loving peoples” wherever communism threatened them. Twenty-four times in the eighteen-minute speech, Truman used the words “free” or “freedom.”
Building on the wartime division of the globe into free and enslaved worlds, and invoking a far older vision of an American mission to defend liberty against the forces of darkness, the Truman Doctrine created the language through which most Americans came to understand the postwar world. More than any other statement a prominent senator would write, this speech established “the guiding spirit of American foreign policy.” Truman succeeded in persuading both Republicans and Democrats in Congress to support his policy, beginning a long period of bipartisan support for the containment of communism. As Truman’s speech to Congress suggested, the Cold War was, in part, an ideological conflict. Both sides claimed to be promoting freedom and social justice while defending their own security, and each offered its social system as a model the rest of the world should follow.

While his request to Congress was limited to $400 million in military aid to two governments (aid that enabled both Greece and Turkey to defeat their domestic foes), Truman’s rhetoric suggested that the United States had assumed a permanent global responsibility. The speech set a precedent for American assistance to anticommunist regimes throughout the world, no matter how undemocratic, and for the creation of a set of global military alliances directed against the Soviet Union. There soon followed the creation of new national security bodies immune from democratic oversight, such as the Atomic Energy Commission, National Security Council, and Central Intelligence Agency (CIA), the last established in 1947 to gather intelligence and conduct secret military operations abroad.
