      Lesson details

      Learning outcome

      I can explain how the arms race led to an increase in Cold War tension between the USA and the USSR.

      Key learning points

      1. The establishment of NATO (1949) and the Warsaw Pact (1955) divided Europe into two rival alliance systems.
      2. The American development of the atomic bomb started an arms race between the USA and the USSR.
      3. In 1953, hopes that new leaders in the USA and USSR would improve relations were short-lived: the arms race continued.
      4. The development of ICBMs (1957) meant the USA and USSR could fire nuclear weapons at targets in different continents.
      5. Both the USA and the USSR developed huge stockpiles of nuclear weapons as a form of deterrence.

      Keywords

      • Arms race - when countries compete with each other to build up their military strength

      • Superpower - a country that has great power and influence globally; the USA and USSR were superpowers during the Cold War period

      • Summit - a meeting between leaders to discuss significant issues or make important decisions

      • ICBM - intercontinental ballistic missile; missiles that could fire a nuclear warhead at targets in different continents

      • Deterrence - using the threat of force to prevent something from happening

      Common misconception

      NATO was established in response to Stalin setting up the Warsaw Pact.

      The Warsaw Pact was a response to NATO's formation in April 1949 (following the Berlin Crisis and Soviet takeover of Czechoslovakia).
