The Brezhnev Doctrine, 1968

The Brezhnev Doctrine was a Soviet foreign policy, first and most clearly outlined by S. Kovalev in a September 26, 1968 Pravda article, entitled “Sovereignty and the International Obligations of Socialist Countries.” Leonid Brezhnev reiterated it in a speech at the Fifth Congress of the Polish United Workers’ Party on November 13, 1968, which stated:
“When forces that are hostile to socialism try to turn the development of some socialist country towards capitalism, it becomes not only a problem of the country concerned, but a common problem and concern of all socialist countries.”
