Ukraine is separate country, and Moldova is separate country, and Belarus is separate country, and Afghanistan is separate country, and Caucasus is separate country, and so on...

Not sure what point you're trying to make. Plus, Caucasus is not a country. Yes, Russia has a lot of international influence outside their borders, but that doesn't mean the ill-informed observation by the GP was meaningful in any way.

Sorry, Georgia and Azerbaijan. So they have influence, including direct military operations, but their influence is not strong enough to make something to single mine?

Let me remember that whole military operation in Ukraine is done by Russia to stop Shell from mining of natural gas in Eastern Ukraine.

If it start drifting away from Russia politically emergence of pro-russian rebels (surprisingly well armed) will be arranged by Putin.

It has never been politically close to Russia, even in the Soviet era, when it was a part of Yugoslavia. (Especially when it was Yugoslavia - Stalin tried to have Tito killed several times. They were both communist countries but that's the only thing common between them.)

Had they not been so warhungry in the 90s, they could be a part of EU and NATO now, like Croatia.
