The Truman Doctrine was a policy set forth by U.S. President Harry Truman on March 12, 1947 stating that the U.S. would support Greece and Turkey with economic and military aid to prevent their falling into the Soviet sphere. Truman stated the Doctrine would be “the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures.” Truman reasoned, because these “totalitarian regimes” coerced “free peoples,” they represented a threat to international peace and the national security of the United States. While his request was limited to $400 million in military aid to two governments, Truman’s rhetoric had assumed that the US had assumed a permanent global resposibility.
If Truman never became president and made this doctrine, Greece and Turkey could have been taken by th Soviet Union and fallen to cummunism. Communism could have spread to major portions of the world as well as to the US. Then the fear of the Americans that the communist will take away their freedom would come true.
