What economic policy aimed to prevent the spread of communism by containing it?

The policy of containment was a strategic approach adopted by the United States during the Cold War, primarily aimed at preventing the further expansion of communism beyond where it already existed. Developed in response to the perceived threat posed by the Soviet Union, containment sought to limit the influence and military power of communist states. This doctrine was articulated in various ways, including through military alliances, economic assistance programs like the Marshall Plan, and direct military engagement in conflicts such as the Korean War and the Vietnam War.

Containment was influential in shaping U.S. foreign policy from the late 1940s until the end of the Cold War. It emphasized the importance of maintaining stability in regions that were under the threat of communist takeover, thus fostering alliances with non-communist countries and providing them with economic and military support. The containment strategy was not only a military response but also included diplomatic and economic measures aimed at curtailing the appeal and spread of communism globally.

In contrast, the other options reflect different approaches or periods. Isolationism refers to a foreign policy that seeks to minimize involvement with other countries, which does not align with the active approach of containment.
