What was the name of President Truman's policy that provided aid to countries threatened by communism?

The Truman Doctrine is the name given to President Harry S. Truman's policy established in 1947 that aimed to provide support to countries resisting the spread of communism. This policy emerged in the context of the Cold War and responded to growing fears about the expansion of Soviet influence around the world, particularly in Greece and Turkey, where communist movements were gaining traction.

Under the Truman Doctrine, the United States committed to providing political, military, and economic assistance to any nation threatened by communism. This was a significant shift in American foreign policy, marking the beginning of a more interventionist approach that aimed to contain the spread of communism globally.

The Marshall Plan, while related, specifically refers to economic aid implemented to help rebuild Western European economies after World War II, which indirectly supported the Truman Doctrine's goals but was not the same policy. The New Deal relates to domestic programs aimed at recovery from the Great Depression rather than foreign policy, and the term Cold War Initiative does not specifically identify a recognized policy or program. Thus, the Truman Doctrine clearly represents the policy designed to counter the threat of communism through aid and support.
