In this film Dr Edwin Bacon talks about Brezhnev’s change in direction and approach after Khruschev, making collective leadership work and the Kosygin reforms. Whilst there were changes from the era of Khruschev, Brezhnev’s response to the Prague Spring in 1968 showed that some things had not changed. The events in Czechoslovakia would lead to the emergence of the Brezhnev Doctrine and his declaration that the Soviet Union would make sure that the Soviet bloc would remain loyal to Moscow.
