Lenin didn't like stalin very much... >>After the incapacitated Lenin's death on 21 January 1924, the party officially maintained the principle of collective leadership, but Stalin soon outmaneuvered his rivals in the Central Committee's Politburo. At first collaborating with Jewish and half-Jewish Politburo members Grigory Zinoviev and Lev Kamenev against Jewish arch-rival Leon Trotsky, Stalin succeeded in marginalizing Trotsky. By 1929, Stalin had also effectively marginalized Zinoviev and Kamenev as well, compelling both to submit to his authority. The intransigent Trotsky was forced into exile. When Boris Bazhanov, Stalin's personal secretary who had defected to France in 1928, produced a memoir critical of Stalin in 1930, he alleged that Stalin made crude antisemitic outbursts even before Lenin's death.[7] https://en.wikipedia.org/wiki/Leon_Trotsky >>Trotsky wrote extensively and polemically against Stalinism. His proletarian internationalism was opposed to Stalin's theory of "socialism in one country". Trotsky's own theory of "permanent revolution" posited (1) that in countries such as Russia, where world capitalism had created a small bourgeoisie, only the proletariat could carry out the tasks of the bourgeois revolution and build socialism (as opposed to the two-stage theory), and (2) that the Soviet Union could not survive surrounded by hostile capitalist states, and that revolutions in the advanced Western countries were required. In his book The Revolution Betrayed (1937), Trotsky argued that the Soviet Union had become a "degenerated workers' state" as a consequence of its isolation, and called for a new political revolution to end bureaucratic dictatorship and restore the democratic values of 1917. In 1938, Trotsky founded the Fourth International as an alternative to the Comintern. In 1940, a Soviet NKVD agent, Ramón Mercarder, **assassinated Trotsky at his home in Mexico.[d] Written out of Soviet history under Stalin**, Trotsky was one of his rivals who did not receive political rehabilitation from later Soviet leaders.[12]
