If you talk about Crimea, they asked their independance, then to join Russia. The referendum was legit. But, the West doesn't like Democracy, obviously. They support a violent Coup and reject an election...
France annexed Mayotte island last decade, after a local referendum. What's the problem with that ? I think you are more Russia hating than you think I'm West hating.
Imperialism is not only a question of military invasion. It's also about spying, economy and propaganda. CIA and NSA are present all over the world, they try to sign unfair "Free-trade" agreement secretly with all their allies etc. I mean, this is a global empire. Russia may have a local influence but I really not fear this country.
