Cold War History: Ideological Confrontation, Nuclear Terror Balance, and the Arc from Berlin Wall to Soviet Collapse
The Cold War’s key structural tensions: **ideological** — George Kennan’s “Containment Policy” (1946 Long Telegram) held Soviet communism was expansionist and must be globally contained; **arms race** — the Soviet Union (1949), Britain (1952), and France (1960) successively developed nuclear weapons, arsenals eventually swelling to ~60,000 warheads (1986 US-Soviet peak); **proxy wars** — both sides backed preferred regimes or forces in third-world countries (Korean War 1950–53, Vietnam War 1955–75, Angola, Afghanistan).
**Cuban Missile Crisis (October 1962)**: the Cold War’s closest moment to nuclear war — the Soviets secretly deployed nuclear missiles in Cuba; the US discovered and instituted a naval blockade; after 13 days of tense standoff, the Soviets agreed to remove missiles (the US secretly promised not to invade Cuba and to remove missiles from Turkey). The crisis led to the “hotline” (established 1963) and clearer crisis management mechanisms.
## Soviet Collapse: Cold War’s End
Gorbachev’s (taking power 1985) **Perestroika** (economic restructuring) and **Glasnost** (political transparency) policies aimed to save the stagnating Soviet system through limited reform but instead accelerated institutional collapse — Eastern European satellite states underwent democratic revolutions in 1989 (Poland, Hungary, East Germany, Czechoslovakia, Romania); the Berlin Wall fell November 9, 1989; the Soviet Union formally dissolved December 25, 1991, giving birth to Russia, Ukraine, and 13 other independent states.
