Whataboutism and projection. You can’t just say “but what about Russia” when people are fighting against North Atlantic imperialism. This article is about North Atlantic imperialism. Mentioning Russian so-called imperialism is whataboutism.
Also, Russia isn’t doing imperialism because it in no way meets the definition of imperialim. It’s economy is smaller than Brazil’s and smaller than South Korea’s. 60% of its exports are raw materials or intermediate materials. India exports 3 times more capital than Russia does. Clearly South Korea and India aren’t imperialist. Russia isn’t either.
