Truman Doctrine

Truman Doctrine, policy first set forth by United States President Harry S. Truman in 1947. The immediate objective of the policy was to send U.S. aid to anti-Communist forces in Greece and Turkey, but it was later expanded to justify support for any nation that the United States government believed was threatened by Communism during the Cold War period.
