The aggressors were the west and the Ukranian "nationalists" (I avoided using the right word) seeking to cancel the history of the people in Ukraine, replacing it with their own absurd version rehabilitating ukrainian nazi collaborationists, giving their imaginary version of the famine before the war (I heard a figure of "60 million killed" from one person), and seeking to cancel Russian language and Russian culture there. In particular in Crimea, where the absolute majority had no ties with Ukranian language or culture.

This is how "separatists" you are complaining about appeared in the first place. And then yes, Russia stepped in, while before it sought only economical and political influence. Just as your beloved west did. And tell me now who owns your land..
