	Summary If NATO and the Warsaw Pact states are learning to live together, with some semblance of normality, the Soviet Union's determination to exercise rigid control over Eastern Europe remains as strong as ever. In 1953, the Soviet Union had suppressed protests by East German workers; in 1956, Soviet tanks crushed the anti-regime rebellion in Hungary. Now it is the turn of Czechoslovakia. While remaining loyal to Communism, the Czech leader, Alexander Dubcek, had begun to introduce liberal reforms but his Prague Spring is terminated in August 1968 when Soviet tanks enter the city.
