Step-by-step explanation:
The foreign policy strategy of opposing the expansion of communism during the Cold War with the Soviet Union was known as containment. This policy was focused on the West's Cold War goal of confining communism to just the Soviet Union and the nations of Eastern Europe, thereby preventing its spread around the globe. The concept of containment was introduced by George F. Kennan in his famous Long Telegram, where he described the Soviet Union as a relentless force committed to the spread of communism. As such, the United States adopted various strategies to ensure the containment of Soviet influence and communism, strictly limiting it to already influenced areas and providing military and economic support to prevent its further expansion.
The foreign policy strategy employed by the United States during the Cold War to counteract the expansion of communism was known as containment. This strategic approach, articulated by George F. Kennan in his influential Long Telegram, aimed to confine the influence of communism primarily to the Soviet Union and Eastern European nations. The core objective of containment was to prevent the global spread of communism. Kennan depicted the Soviet Union as an unyielding force dedicated to promoting communist ideology.
