If there were, they would collectively take a much much harder stance with Russia. This is why Eastern Europe is so much more pro-USA than Western Europe.
Crimea was part of Russia for centuries, it has 60%+ citizens of Russian ethnicity, and it had its government toppled and neo-nazis and nationalists come to power in a NATO proxy power play.
It would be like Mexico having an area (say Baja California) with 60% WASP Americans, that has been historically part of the US, and having Mexico's government toppled with the help of a foreign superpower and used against the US.
Would the US annex Baja California then?
Then again, the US have already annexed Texas, Florida, California, New Mexico, Arizona, etc, from Mexico, so there's that...
Of course, the US government supports affiliated NGOs as it does elsewhere in the world (and as everyone does), but "power play" means something else.
*supported as in created, instructed and financed.
But it wants the Soviet Union back.
>> and is not a threat to anyone
Ukraine would not agree with that. Russia took Crimea and is supporting a civil war in eastern Ukraine. This may not be much for you but
>> except immediate neighbors
Yeah except the immediate neighbours and then the neighbours of the neighbours. Think of the Soviet Union era...
Speaking of neighbours Denmark, Sweden, Lithuania and few others are pretty close to Russia. I guess they are on your list of doomed neighbours anyway.
