Yes, I definitely read it as a barb aimed directly at the Soviet communists, though I think there's a predictive component to it as well. I don't know my Russian/Soviet history well enough to have connected the dots with guys like Kamenev and Zenoviev, but Stalin and Trotski, yes.
BTW, have you seen the movie, Brazil? I would say you probably have, and I'm not telling you anything you don't know already, but if you haven't, go rent it pronto. It is an amazingly clever retelling of 1984 -- truly a fine piece of dark satire.
Brazil is really far out.
