History
The Cold War (1947–1991) — quick study summary
The Cold War was a 44-year geopolitical struggle between the capitalist West (USA, NATO) and communist East (USSR, Warsaw Pact). It never erupted into direct war between the superpowers — instead they fought proxy conflicts (Korea, Vietnam, Afghanistan) and competed in arms, space, and ideology. Key flashpoints: Berlin Blockade (1948–49), Cuban Missile Crisis (1962), Vietnam War, détente in the 1970s, escalation under Reagan. The Soviet system collapsed under economic strain; the Berlin Wall fell in 1989, the USSR dissolved in 1991.
