Brezhnev Doctrine The Brezhnev Doctrine was a Soviet foreign policy outlined in 1968 which called for the use of Warsaw Pact (but Russian-dominated) troops to intervene in any Eastern Bloc nation which was seen to compromise communist rule and Soviet domination. It could be doing this either by trying to leave the Soviet sphere of influence or even moderate its policies rather than stay in the small parameters allowed to them by Russia. The Doctrine was seen clearly in the Soviet crushing of the Prague Spring movement in Czechoslovakia which caused it to be first outlined. At one point in time, the USSR had control over Czechoslovakia and the rebellion of Prague Spring attempted to cut Czechoslovakia's ties with the Russians. Using the Brezhnev Doctrine, Leonid Brezhnev allowed the Russian military to step in and put down the rebellion in order to maintain socialism. Brezhnev used the doctrine to justify Russia's intervention in Czechoslovakia and stated that socialist and communist nations could advance as long as their form of government was not compromised or threatened. Following the death of Brezhnev, his doctrine and martial died with him. Questions: 1. What was Prague Spring? 2. What did Leonid Brezhnev do about Prague Spring? 3.
