What was a key aspect of George F. Kennan's containment policy?

George F. Kennan's containment policy fundamentally aimed at limiting the spread of communism beyond its existing boundaries, particularly in Europe and Asia after World War II. This policy emerged from the belief that the Soviet Union would expand its influence if not actively contained. By defining the strategy of containment, Kennan advocated for diplomatic, economic, and psychological measures to resist Soviet expansion without direct military confrontation, especially in regions where communist movements might gain momentum.

This approach led to significant U.S. actions during the Cold War, including support for anti-communist regimes and initiatives such as the Marshall Plan, which sought to stabilize European economies and prevent the spread of communism by fostering political stability. The emphasis was on using a variety of tools to counteract Soviet influence rather than relying solely on military solutions or direct confrontation.
