In 1968 Warsaw Pact forces entered Czechoslovakia to end a reform movement. The Soviet leadership then said that socialist states had a duty to act when socialism in any one of them was in danger. Which doctrine is this?
- The statement is about intervention inside the socialist bloc, so it is a Soviet doctrine, not an American one.
- Peaceful coexistence concerns relations with capitalist states, and 'socialism in one country' concerns building socialism at home. Neither fits.
- The claim of a right to intervene in a socialist state, made in 1968, is the Brezhnev Doctrine.
Answer: The Brezhnev Doctrine.
