The Truman Doctrine established the following foreign policy for the United States:

1. Containment of Communism: The Truman Doctrine focused on containing the spread of communism, particularly in Europe. It aimed to provide support to countries threatened by communist expansion.

2. Support for Free Peoples: The doctrine stated that the U.S. would support free peoples who were resisting attempted subjugation by armed minorities or by outside pressures. This support included economic and military aid to help these nations resist communist influence.

3. Implementation of the Policy: The Truman Doctrine was put into action through various means, including the Marshall Plan which provided economic assistance to help rebuild Western European economies after World War II. Additionally, the U.S. provided military aid and support to countries like Greece and Turkey to prevent the spread of communism in those regions.

By establishing the Truman Doctrine, the United States set the stage for its active involvement in global affairs during the Cold War era, shaping its foreign policy towards containing communism and supporting democratic nations.
