Harry S. Truman (or Truman Doctrine)

Harry S. Truman was the 33rd President of the United States, serving from 1945 to 1953. The Truman Doctrine, announced in 1947, was a policy he adopted to contain the spread of communism. It involved providing political, military, and economic aid to countries threatened by communism, particularly Greece and Turkey at the time. This approach marked a shift from previous policies, emphasizing active intervention to prevent the expansion of Soviet influence during the Cold War. Essentially, Truman aimed to support free nations and promote stability worldwide, shaping U.S. foreign policy for decades.
