> It wasn't colonialist, in that the USSR did not expand into overseas areas of nonwhite people That is a peculiar definition of "colonialist". For instance, the ancient Romans colonized Great Britain, despite the fact that the Romans and the Britons were both "white". The Arabs colonized Spain, despite the fact that the Arabs were "non-white" (by some definitions) and the Spaniards were "white". The Mongols colonized a whole bunch of areas, of pretty much every ethnicity that exists in Eastern Europe and a large swath of Asia. And so on.
