it's because they see 'western civilisation' as a product of the united kingdom, they even refer to the us as 'anglo-saxon' despite the us now being 50% white. i think it's trauma, their revolution was a mistake and all they have now is the rotting ideological foundations it was built upon, so instead of admitting they were wrong and having to rebuild russia from scratch they instead live-action-roleplay as though it's the early 1900s and they're a world power contesting a superpower.
