Lenin feared social structurelessness more than bourgeois or nationalist resurgence

Evidence

It seems clear that in these purely practical political matters Lenin followed his great instincts for statesmanship rather than his Marxist convictions; his policy, at any rate, proves that he was more frightened by the absence of social and other structure than by the possible development of centrifugal tendencies in the newly emancipated nationalities or even by the growth of a new bourgeoisie out of the newly established middle and peasant classes. — Hannah Arendt, The Origins of Totalitarianism, 762
