You call Russia imperialist. Materially, it is not. Imperialism requires export of capital, enforced unequal exchange, subordinated peripheral economies to a core. Russia does not command the IMF. It does not control SWIFT. It does not own global platforms or academic gatekeeping. It is an oligarchic kleptocracy with regional ambitions and security concerns. Conflating it with US hegemony serves Western propaganda.

Also it's not just the US it's the imperial core as a whole: Europe, NATO, Five eyes and their vassals like the ROK and Japan.
