Containment

The Policy of Containment

Through the Truman Doctrine and the Marshall Plan, the USA tried to stop communism spreading. This was part of a policy known as ‘containment’.

Spread of communism

Spread of communism

  • Truman (leader of America) was worried that communism would be an attractive option for European citizens, who were very poor after the war.
  • Many countries had been liberated (freed) by the Soviets at the end of the war. He thought that this might give them reason to support communist causes.
The 'domino effect'

The 'domino effect'

  • Poland, Romania and Bulgaria already had communist governments.
  • Truman feared this may spread to countries like Greece and Turkey, who struggled to fight off communist revolutions.
  • This could cause a ‘domino effect’: if one country fell to communism, more countries would too.

The Truman Doctrine
