I think that is what peeves me too. Not so much that they come here but that many in the younger crop continue to peddle the Putin era anti-American self-righteousness they were inculcated in back home. They'll even vote for Putin while abroad. They want their country to be feared. They just can't live in it...
Many take advantage of America while resenting it.
People who came here for asylum during the Soviet era have much better attitudes and love America not resent it. My observations.
Are they all coming here? Many are. Others are going to Germany or to the former Soviet Republics. Russians were dying to leave those places 20 years ago and now many are going back. I guess a lot of the natives still speak Russian and won’t make you learn their language. Other Russians are going to Israel, Italy, Spain, and Canada.
