Which U.S. foreign policy was primarily aimed at limiting the spread of communism?

The containment policy was primarily aimed at limiting the spread of communism, particularly during the Cold War era. This strategy emerged in response to the belief that if one country fell to communism, neighboring countries would also likely fall in a domino effect. Developed by leaders such as George F. Kennan, the policy advocated for various means to halt the expansion of Soviet influence and communism worldwide, through diplomatic, military, and economic efforts.

The ultimate goal of containment was not necessarily to eliminate communism where it already existed but to prevent its further spread into new regions, particularly in Europe and Asia. This policy influenced significant U.S. actions, including the Truman Doctrine, the Marshall Plan, and military interventions in Korea and Vietnam, all of which were aimed at combating communist movements and supporting governments that were potentially threatened by communism.

Other foreign policy choices such as isolationism typically focused on avoiding involvement in foreign conflicts, while expansionism suggests a push to extend U.S. territories or influence, often unrelated to the dynamics of communism. Interventionism may involve direct military action but does not specifically signify the strategic approach of containing communism, as it can refer to a broader engagement in international affairs without that specific focus.
