"The bourgeoisie, it now appeared, was digging its own grave. That, at least, was the argument Lenin put forward, at first from exile, and then after the overthrow of Tsar Nicholas II early in 1917, from within Russia itself. Lenin differed from Marx and Engels, however, in his determination to move from theory to action: his coup d'état in November—for that is what it was—remains as striking an example as exists of the extent to which one person can change the course of history. Or, as Lenin would have put it, drawing on Marx, by which the "conscious vanguard of the proletariat" can accelerate history toward its scientifically predetermined conclusion. What the Bolshevik "revolution" meant was that one state had gone beyond trying to save capitalism: it had, in the middle of a war capitalists had started, declared war on capitalism itself. And if the expectations of Lenin and his followers were correct, the citizens of other states—themselves embittered by capitalism and battered by war—would soon seize power and do the same. The irreversible engine of history guaranteed it."
