Communism as operated by Lenin et al, is just another name for Russian imperialism, with a twist so the suckers in the West would have a plausible excuse to support it. The Chinese version, is Mao (and successors) as the emperor, without the trappings of world-wide proletarian revolution. This has evolved into a dictatorship of the fascist kind in both countries. Private property, without the true respect that such property deserves, xenophobia, and authoritarianism.
Real Marxist Communism in Russia died when the expected worldwide revolution did not follow quickly on the heels of the October Revolution. Soon in 1924, Stalin publicized his “Socialism in One Country” idea and red orthodoxy took more and more of a backseat to nationalism. A subset of Stalin’s butchery was dedicated to eliminating the true believers of Communism.
