Truman told Congress that "it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures." Truman contended that because totalitarian regimes coerced free peoples, they automatically represented a threat to international peace and the national security of the United States. Truman argued that if Greece and Turkey did not receive the aid, they would inevitably fall out of the United States' sphere of influence and into the communist bloc, with grave consequences throughout the region.

The Truman Doctrine was informally extended to become the basis of American Cold War policy throughout Europe and around the world. It shifted U.S. policy toward the Soviet Union from a wartime alliance to containment of Soviet expansion, as advocated by diplomat George F. Kennan.

Turkish Straits crisis

At the conclusion of World War II, Turkey was pressured by the Soviet government to allow Soviet shipping to flow freely through the Turkish Straits, which connected the Black Sea to the Mediterranean. As the Turkish government would not submit to the Soviet Union's requests, tensions arose in the region, leading to a show of naval force on the site of the Straits. Since British assistance to Turkey had ended in 1947, the U.S. dispatched military aid to ensure that Turkey would retain chief control of the passage. Turkey received $100 million in economic and military aid and the U.S. Navy sent the Midway-class aircraft carrier USS Franklin D. Roosevelt.
