Cold War

Ideological, political, and economic tensions from 1945 to 1989 between the USSR and Eastern Europe on the one hand and the USA and Western Europe on the other. The Cold War was fuelled by propaganda, undercover activity by intelligence agencies, and economic sanctions; and was intensified by signs of conflict anywhere in the world. Arms-reduction agreements between the USA and USSR in the late 1980s, and a reduction of Soviet influence in Eastern Europe, led to a reassessment of positions, and the ‘war’ was officially ended in December 1989.

The term ‘Cold War’ was first used by Bernard Baruch, advisor to US President Truman, in a speech made in April 1947. He spoke about Truman's intent for the USA to ‘support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures’ (see Truman Doctrine).

Origins
Mistrust between the USSR and the West dated from the Russian Revolution of 1917 and contributed to the disagreements which arose during and immediately after World War II over the future structure of Eastern Europe. The Atlantic Charter, signed in 1941 by the USA and the UK, favoured self-determination; whereas the USSR insisted on keeping the territory obtained as a result of the Hitler–Stalin pact of August 1939. After the war the USA was eager to have all of Europe open to Western economic interests, while the USSR, afraid of being encircled and attacked by its former allies, saw Eastern Europe as its own sphere of influence and, in the case of Germany, was looking to extract reparations. As the USSR increased its hold on the countries of Eastern Europe, the USA pursued a policy of ‘containment’ that involved offering material aid to Western Europe (the Marshall Plan) and to Nazi-victimized countries such as Greece and Turkey. The USSR retaliated by setting up Comecon to offer economic aid to countries within its sphere of influence. Berlin became the focal point of East–West tension (since it was zoned for military occupational governments of the USA, UK, France, and USSR, yet was situated within what was then Soviet-controlled East Germany). This culminated in the Soviet blockade of the US, British, and French zones of the city in 1948, which was relieved by a sustained airlift of supplies (see Berlin blockade). In 1961 the East Berlin government began construction on the Berlin Wall to prevent the flow of East German people to the West.

Increasing tensions
The growing divisions between the capitalist and communist worlds were reinforced by the creation of military alliances: the North Atlantic Treaty Organization (NATO) was set up in the West in 1949, and was followed in the East by the Warsaw Pact in 1955. Tensions between the two blocs increased significantly at a number of points during the following two decades, and were prompted on the one hand by the USSR's military suppression of anticommunist revolutions – the East German revolt in 1953, the Hungarian uprising in 1956 (see Hungary, the Hungarian national uprising), and the revolt known as the Prague Spring in Czechoslovakia in 1968; and on the other hand by US participation in the Vietnam War (1961–75) and the Cuban missile crisis of 1962, during which the two superpowers came closer than ever before to nuclear war. The crisis was initiated by the siting of Soviet rockets in Cuba in October 1962, after which US President Kennedy, by means of military threats and negotiation, forced the Soviet leader Nikita Khrushchev to back down and dismantle the missiles. During the 1960s the non-aligned movement appeared – a group of nations which adopted a position of strategic and political neutrality towards the USA which was accused of pursuing a policy of US imperialism; and towards the USSR, who was seen to be promoting communist ideology through Soviet imperialism.

During the late 1970s and 1980s, tensions between the two blocs were exacerbated still further: first by the USSR's invasion of Afghanistan in 1979 and the resultant war which continued until 1987; and then by the aggressive foreign policy pursued between 1981 and 1989 by US President Ronald Reagan. In 1980 and 1981, for example, the USA supported the newly formed Solidarity trade-union movement in Poland, and in 1983, Reagan publicly referred to the USSR as an ‘evil empire’. The major point of tension, however, arose with the increasing intensification of the arms race (see nuclear warfare), which placed heavy demands upon the economies of both countries, and was given a quite new direction by Reagan's insistence on militarizing space through the Strategic Defense Initiative, popularly known as Star Wars.
