Berlin, Korea and Cuba: how close the world came to nuclear war.
Key ideas
Crises tested the limits
In 1962 the Cuban Missile Crisis brought the world closer to nuclear war than ever before, as US and Soviet leaders confronted each other over missiles in Cuba. The crisis ended with a negotiated withdrawal — and taught both sides to build better communication, including the Washington–Moscow hotline.
Rivals, not warriors
The superpowers never fought each other directly because nuclear weapons made total war suicidal. Instead they competed through alliances (NATO founded 1949, the Warsaw Pact 1955), arms races, propaganda and proxy wars. The Cold War was a struggle for influence fought everywhere except the direct battlefield.
Key term — Deterrence: Preventing attack by threatening devastating retaliation — the logic behind nuclear arsenals.
In October 1962 the USA discovered Soviet nuclear missiles in Cuba. Explain why this crisis was resolved without war.
Establish the stakes: US cities were now in range of Soviet missiles, and both sides feared a first strike. Note Kennedy's choice: a naval 'quarantine' of Cuba rather than immediate bombing, buying time for negotiation. Note Khrushchev's calculation: the missiles were leverage, and he could trade their removal for a US pledge not to invade Cuba. Conclude: secret diplomacy plus mutual fear of nuclear war produced a deal — missiles out of Cuba, and a hotline to prevent repeats.
Answer: War was avoided because Kennedy chose a blockade that allowed time for negotiation, Khrushchev accepted a face-saving trade (missiles withdrawn for a no-invasion pledge), and both leaders' fear of nuclear escalation pushed them towards secret diplomacy rather than force.
- Assuming nuclear weapons made war impossible Deterrence reduced the risk but crises like Cuba show how close miscalculation came. Leaders managed the danger; the weapons did not remove it.
- Saying the Cold War was only about the USA and USSR It drew in the whole world: Korea, Vietnam, Afghanistan and many decolonising states became Cold War battlegrounds, often at terrible local cost.
Practice
The Cuban Missile Crisis, over Soviet nuclear missiles placed in Cuba.
Direct war risked nuclear escalation, which would have been suicidal for both sides.
Gorbachev's reforms destabilised Soviet control, and mass protests in Eastern Europe (e.g. the fall of the Berlin Wall in 1989) ended communist rule; the USSR dissolved in 1991.
The US policy of preventing the spread of Soviet influence, announced in 1947.
