A World Divided: Superpower Relations, 1943-72

Overview

In 1943 the United States and the Soviet Union were allies fighting the same enemy. Within four years they were describing each other as the principal threat to civilisation, and within twenty they came closer to nuclear war than at any other point in history. No shot was ever fired directly between them, which is why the period is called a cold war, but millions died in the conflicts it produced elsewhere.

This note takes you from the wartime conferences through the division of Europe, the Berlin Blockade, Korea, Hungary, the three crises of Berlin, Cuba and Czechoslovakia, and on to the arms control agreements of detente. It also gives you the tools to argue about the question historians have never settled: who was responsible?

Objectives

  1. Reasons for the Cold War: long-term rivalry, ideological differences, tensions during the Second World War, conferences at Tehran, Yalta and Potsdam, the Soviet Union and Eastern Europe, the attitudes of Truman and Stalin
  2. Early developments in the Cold War, 1945-49: Soviet expansion in Eastern Europe, the iron curtain, the Truman Doctrine, the Marshall Plan, Cominform and Comecon, disagreements over Germany, the Berlin Crisis, NATO and the creation of two Germanys
  3. The Cold War in the 1950s: the Korean War, the Warsaw Pact, Khrushchev and peaceful co-existence, Soviet rule on Hungary, the Soviet invasion of Hungary, the nuclear arms race
  4. Three crises: Berlin, Cuba and Czechoslovakia: the U2 incident, the Berlin Wall, the Bay of Pigs invasion, the Cuban Missile Crisis, the Soviet invasion of Czechoslovakia and the Brezhnev Doctrine
  5. The Thaw and moves towards Detente, 1963-72: the Hotline, Test Ban Treaty, Outer Space Treaty, Nuclear Non-proliferation Treaty, reasons for Detente, SALT talks and treaty

Lesson Note

The alliance of 1941 to 1945 was one of convenience against Germany, and the distrust underneath it was older than the war. The United States and Britain had sent troops to support the anti-Bolshevik side in the Russian Civil War after 1918; the United States did not recognise the Soviet government until 1933; and Stalin had signed the Nazi-Soviet Pact in August 1939. During the war, Stalin repeatedly pressed for a second front in western Europe and did not get one until June 1944, which he interpreted as the Western allies waiting for Germany and the USSR to exhaust each other.
