In October 1964, Khrushchev was replaced by Leonid Brezhnev, who remained in office until his death in November 1982. During his reign, Stalin's controversies were de-emphasized. Andres Laiapea connects this with "the exile of many dissidents, especially Aleksandr Solzhenitsyn", though whereas Laiapea writes that "[t]he rehabilitation of Stalin went hand in hand with the establishment of a personality cult around Brezhnev". Political sociologist Viktor Zaslavsky characterizes Brezhnev's period as one of "neo-Stalinist compromise" as the essentials of the political atmosphere associated with Stalin were retained without a personality cult. According to Alexander Dubček, "[t]he advent of Brezhnev’s regime heralded the advent of neo-Stalinism, and the measures taken against Czechoslovakia in 1968 were the final consolidation of the neo-Stalinist forces in the Soviet Union, Poland, Hungary, and other countries". Brezhnev described the Chinese political line as "neo-Stalinist". American political scientist Seweryn Bialer has described Soviet policy as turning towards neo-Stalinism after Brezhnev's death.
