What's quite amusing is how True Leftists rave on attacking US "imperialism" all the time yet then go ahead and defend Putin's imperialistic actions.
To some extent, ya, though in the Russian example isn't there overlap between imperialism and irredental claims to territories adjacent their borders that were under Russian control for all but a couple decades since the late 18th century? The way Crimea was reclaimed was admittedly distasteful but not necessarily bad in its final results, though your point makes sense for ongoing aggression in other parts of Ukraine.
