One obvious difference between the Soviet Union and Russia is that the Soviet governing elite embraced Marxism-Leninism and its objective of world revolution. Today’s Russia is not a messianic power. Its economic system is a rather mundane variety of corrupt crony capitalism, not rigid state socialism. The political system is a conservative autocracy with aspects of a rigged democracy, not a one-party dictatorship that brooks no dissent whatsoever.
