The changes that Beriya and Malenkov had in mind in their revisionist version of de-Stalinization might have altered the regime in principle. Furthermore, given the depth of the crisis in the communist world and the intensity of the struggle for power in the Soviet leadership, if those changes had been pursued, they might have developed a momentum of their own and brought about a radical transformation of Soviet society regardless of the wishes of their initiators and with incalculable consequences for the Soviet Union and the rest of the communist and noncommunist world.
It was not without reason that Beriya was shot for being an "agent of world imperialism," and that Malenkov was dismissed as Prime Minister in 1955 for "departing from Lenin's and Stalin's theories."
Their ideas had indeed threatened the regime and could have led to a situation that they would have been unable to control.
The exposure of Stalin's mistakes gave a substantial boost to anticommunism in general and to anti-Stalinist feeling in both the bloc and non-bloc communist parties.
Revolts occurred in Georgia, Poland, and Hungary. The crisis in many other communist parties deepened. Khrushchev's response was to revert to Stalinist methods. The security service was strengthened; armed force was used to crush revolt in the Soviet Union and Eastern Europe.
