Eh, I don’t buy it. To me it seems just an excuse. Both Russia and China at one point were full state run centrally planned economies. Communist countries made up half the world (leaving aside third world countries), half of Europe, lots of population and plenty of natural resources. There was no reason why they couldn’t succeed if they banded together with the superior economic theory.
But now you are telling me that they couldn’t help the global south, and therefore Russia and China had to abandon communism and switch to full blown capitalism? To beat the US at capitalism? And then go back to communism?
Hot take: they are both just as bad and imperialistic as the US, selfish to the core, only trying to become the top dog on the world stage, by any means possible. Not that hot actually, it’s been the same shit since forever
