Good points. I also wouldn't be opposed to accepting that capitalists in Russia would/will try to become imperialistic in the monopoly of finance capital sense. In the one hand, the logic of capital might force their hand. On the other hand, capitalists are gonna capitalist, in part because they fetishise the hoarding of wealth like everyone else living under capitalism.

Whether Russian imperialism becomes a realistic possibility, though… I'd be interested in seeing some stats on that, interpreted in light of the idea that the next type of multipolarity will be quite different to the one at the turn of the twentieth century. Ig if anyone's done that leg work it'd be Michael Hudson but I've not come across it if he has.
