8.2 The Cold War

Two Superpowers, Two Systems

After WWII, the United States and Soviet Union emerged as rival superpowers with opposing ideologies: capitalism/democracy vs. communism. The Cold War (1947–1991) was a global struggle for influence involving military alliances like NATO (US-led) and the Warsaw Pact (Soviet-led), economic aid programs like the Marshall Plan, and the constant threat of nuclear war rather than direct conflict.

Proxy Wars and Containment

Direct US-Soviet combat was avoided; instead, the superpowers fought proxy wars in Korea, Vietnam, and Afghanistan, arming opposing sides. The US pursued a policy of containment to stop communism's spread (Truman Doctrine, Domino Theory). Events like the Cuban Missile Crisis (1962) brought the world close to nuclear war, while the Berlin Wall symbolized the ideological divide in Europe.

Global Reach of the Cold War

The Cold War shaped decolonization, as new nations often aligned with the US, USSR, or the Non-Aligned Movement (e.g., Bandung Conference). Both superpowers provided military and economic aid to influence newly independent states in Africa, Asia, and Latin America, turning local conflicts into extensions of superpower rivalry.
