condemned Stalin's cult of personality in his Secret Speech to the Twentieth Party Congress in 1956 and instituting de-Stalinization and relative liberalization (within the same political framework). Consequently, some of the world's communist parties who previously adhered to Stalinism abandoned it and, to a greater or lesser degree, adopted the positions of Khrushchev except for the German Democratic Republic and the Socialist Republic of Romania. Others, such as the Chinese Communist Party, chose to split from the Soviet Union, resulting in the Sino-Soviet split. The ousting of Khrushchev in 1964 by his former party-state allies has been described as a Stalinist restoration by some, epitomized by the Brezhnev Doctrine and the apparatchik/nomenklatura "stability of cadres", lasting until the period of glasnost and perestroika in the late 1980s and the fall of the Soviet Union. Maoism and Hoxhaism Mao Zedong famously declared that Stalin was 70% good and 30% bad. Maoists criticized Stalin chiefly regarding his view that bourgeois influence within the Soviet Union was primarily a result of external forces, to the almost complete exclusion of internal forces, and his view that class contradictions ended after the basic construction of socialism. However, they praised Stalin for leading the Soviet Union and the international proletariat, defeating fascism in Germany and his anti-revisionism. Taking the side of the Chinese Communist Party in the Sino-Soviet split, the People's Socialist Republic of Albania remained committed, at least theoretically, to its brand of Stalinism (Hoxhaism) for decades after that under the leadership of Enver Hoxha. Despite their initial cooperation against "revisionism", Hoxha denounced Mao as a revisionist, along with almost every other self-identified communist organization worldwide, resulting in the Sino-Albanian split. This effectively isolated Albania from the rest of the world, as Hoxha was hostile to both the pro-American and pro-Soviet spheres of influence and the Non-Aligned Movement under the leadership of Josip Broz Tito, whom Hoxha had also previously denounced. Trotskyism Trotskyists argue that the Stalinist Soviet Union was neither socialist nor communist but rather a bureaucratized degenerated workers' state—that is, a non-capitalist state in which exploitation is controlled by a ruling caste which, although not owning the means of production and not constituting a social class in its own right, accrued benefits and privileges at the expense of the working class. Trotsky believed that the Bolshevik Revolution needed to be spread all over the globe's working class, the proletarians, for world revolution. However,
