• Identify the key factors that contributed to the strength and appeal of communism in the postwar era.

After World War II ended in 1945, the alliance between the United States and the Soviet Union dissolved. With their common enemy gone, deep political and economic differences came to the surface. President Harry S Truman grew more suspicious of Joseph Stalin than his predecessor had been, especially as the Soviets broke their promises of free elections in Eastern Europe. This growing distrust replaced the wartime partnership with fear, setting the stage for a new global struggle.

Feeling threatened after WWII, the Soviet Union created a buffer zone on its western border. Stalin used his army to install communism in Eastern European countries, suppressing free elections and turning them into satellite nations. In a 1946 speech, Winston Churchill warned that an “iron curtain” had descended across Europe. Note that this phrase came to symbolize the stark division between the democratic West and the communist East for over forty years.

In the aftermath of World War II, widespread poverty made many people desperate for change. Communism appealed to them by promising to end poverty and create a classless society with guaranteed work and education. In many poorer nations, communist organizers used this message to build support, sometimes forming guerrilla forces to fight existing governments. This potent appeal helped communism spread as a powerful global force after 1945, challenging Western-style democracies.

Alarmed by the Soviet takeover of Eastern Europe, the United States sought a way to stop communism’s spread. President Truman, guided by diplomat George Kennan, adopted the policy of containment. The goal was not to fight the Soviets where they already were, but to prevent them from expanding their influence into new areas. This “get tough” strategy received bipartisan support and became the cornerstone of American foreign policy during the emerging Cold War.

President Truman's policy of containment sparked a fierce debate in the United States. Some critics believed it was too weak and demanded direct action against the Soviet Union. However, columnist Walter Lippmann argued the policy was dangerously broad, warning it would commit the U.S. to defending all anti-communist governments. Lippmann famously named this tense new global rivalry the “Cold War,” a term that perfectly described the icy standoff between the superpowers.
