stop Communism.a result, 1955-1963 was the time of GREATEST tension in the Cold War.and HungaryU2 Crisis and the Berlin Wallremained high throughout the late 1950s. The America and British presence in West Berlin was a huge problem for the Russians - particularly because hundreds of thousands of eastern Berliners were fleeing every month into West Berlin (this was an embarrassment for the Communists, never mind the large numbers of skilled workers they were losing). A Summit Meeting was arranged in Paris for 14 May 1960 to discuss Berlin and the arms race.days before the meeting, however, the Soviets shot down an American U2 spy plane. Although they claimed at first it was an off-course weather plane, the Americans had to admit it was a spy plane when the Russians produced the pilot, Gary Powers. As a result, the first thing Khrushchev did at the summit was to demand an apology from President Eisenhower. When Eisenhower refused, Khrushchev went home, and the summit collapsed. It was a very frightening time. If the two sides resorted to all-out nuclear war, their stockpiles of nuclear weapons guaranteed that all life on earth would be wiped out.1961, nearly 2,000 East Germans were fleeing into West Berlin every day. At the Vienna summit of June 1961, Khrushchev again demanded that the Americans leave West Berlin. Kennedy refused - and on 25 July he increased America s spending on weapons. On 13 August, Khrushchev closed the border between East and West Berlin - and built a wall. The Berlin Wall became a symbol of the Cold War.Crisis and the Berlin Wallclose to war did the world come over Cuba in 1962?, The Americans were becoming more aggressive. In 1959, the Communist leader Fidel Castro took power in Cuba. Since Cuba was only 100 miles away from Florida, this was as much a problem for them as West Berlin was for the Russians. In 1961, the Americans elected a new President, John F Kennedy, who promised to get tough on Communism., Kennedy s attempts to get tough went wrong. His actions at the Vienna summit had merely caused the Berlin Wall. When Castro made a trade agreement with Russia, the Americans stopped trading with Cuba; in retaliation, Cuba nationalised all American-owned companies. Then in April 1961 the CIA supported an attempted invasion of Cuba by anti-Castro Cuban exiles at the Bay of Pigs; it failed miserably, greatly embarrassing Kennedy. Even worse, as a result, in September 1961, Castro asked Russia for - and was publicly promised - weapons to defend Cuba against America. On 14 October 1962 an American U2 spy-plane took pictures of a nuclear missile base being built on Cuba. s advisers told him he had 10 days before Cuba could fire the missiles at targets in America. For the next fortnight, the world stood on the brink of global nuclear war. Fearing a military strike would lead to hot war, Kennedy decided to blockad...
