The thing is, Russia is exactly the polar opposite of “supporting bourgois states that fight against imperialism” or being “under imperialist aggression.” Those statements describe states like Ukraine

You think that a state that has invaded Iraq, Syria, Iran, and other places, and has been trying to formally join the gang of other invaders of Iraq and Afghanistan as ‘fighting against imperialism’. You are silly.

Also, what do you think a state should do when the most prolific invader in the world - NATO - starts amassing troops near that state’s borders, especially after conducting a coup d’etat against a neighbouring state?
