Key takeaways
- The Berlin Wall was built by East Germany on 13 August 1961 to stop the flow of refugees fleeing to the West through Berlin, which was embarrassing the Communist bloc.
- Kennedy did not tear the Wall down, but used it for propaganda: his 1963 'Ich bin ein Berliner' speech presented it as proof of Communist failure.
- The Cuban Missile Crisis (16–28 October 1962) began when American U2 planes photographed Soviet nuclear missile sites being built on Cuba, 90 miles from the USA.
- Kennedy imposed a naval 'quarantine' (blockade); after 13 days Khrushchev agreed to remove the missiles in exchange for a US pledge not to invade Cuba and a secret removal of US missiles from Turkey.
- The crisis was the closest the Cold War came to nuclear war; it led to the Moscow–Washington 'hotline' and the first steps towards easing tension.
