26 сент 1968 г. - Brezhnev Doctrine

Описание:

The Doctrine is a foreign policy stating that the Soviet Union is able to intervene, including using the military, in countries where socialist rule is under attack. The doctrine was mainly a response to the Prague Spring, a period of liberalization in a Soviet-bloc country Czechoslovakia by new leader Alexander Dubček. The doctrine limited reforms for Soviet bloc countries for a number of years.
