The Arms Race
History: KS3, topic 20.1.13
The Arms Race
The Soviet Union emerged as a nuclear player in 1949. This then became an arms race with the USA.

Timeline - bombs
- 1945 - USA drops atomic bombs on Hiroshima and Nagasaki.
- This brought the Second World War to an end.
- 1949 - USSR tests an atomic bomb.
- 1952 - USA develops Hydrogen bomb.
- 1953 - USSR tests Hydrogen bomb.

Timeline - missiles and submarines
- 1957 - USA successfully tests Intercontinental Ballistic Missile (ICBM).
- 1957 - USSR successfully tests ICBM.
- 1959 - USA released Polaris submarines.
- These submarines could fire nuclear missiles very close to the USSR from the sea.

Mutually Assured Destruction (MAD)
- Until 1949, the USA believed the best strategy against the Soviet Union in the event of war was to use its nuclear weapons.
- By the 1950s, nuclear weapons had been developed which contained bigger warheads and would have destroyed both sides (Mutually Assured Destruction).
- This made using nuclear weapons less attractive.

The Warsaw Pact
- The Warsaw Pact (May 1955) created an alliance to directly rival NATO.
- The alliance included:
- The USSR, Poland, Hungary, Czechoslovakia, Bulgaria, Romania, East Germany (GDR), Albania.
- This alliance bonded the countries even more closely.

Avoiding war
- The arms race became one of the most challenging issues of the Cold War.
- From the 1950s onwards, leaders on both sides wanted to show their military and nuclear strength.
- But because nuclear war would destroy both countries, they had to find ways to solve disputes without them leading to war.
