The Truman Doctrine and containment policy marked a pivotal shift in U.S. foreign policy after World War II. Responding to Soviet expansionism, these strategies aimed to prevent the spread of communism through economic aid and military support to threatened nations.
This approach shaped the Cold War landscape for decades. The Marshall Plan rebuilt Western Europe, while NATO formed a military alliance against Soviet aggression. Meanwhile, the Soviet Union expanded its influence, leading to the Iron Curtain dividing Europe.
