Yes, serious question. It really doesn't have anything to do with whether russia is communist or not or an oligarchy or not, they see us as a competitor at best and an enemy at worst. Trump is making America much stronger. That is not an advantage for russia in any way.
Bunker? See what's been going on? Is that a serious comment?
A competitor in what way?
Trump has:
Froze aid to the Ukraine while in the midst of a war with Russia .... Russian were smiling
Withdrew troops from Syria... Russian were giddy
Called for Russia to be re-admitted into the G7... Russians were like "he's in our corner"
Eased sanctions on oligarch Deripaska... Putin smiles
Thanked Putin for expelling diplomats because "we're trying to cut down on payroll" .... Putin's like "just doing you a favor bro"
Signed sanctions, reluctantly, due to veto proof majorities... Putin was mad... but knew he had a friend in the WH
Gave out classified intelligence, off the cuff, in the Oval Office.... Putin thinks "what an idiot, thanks for the info"
Refused to acknowledge Putin was a killer, and then stating "you think our country is so innocent?" Putin, gives a odd look and thinks "He can't be that dumb, but I'll take it!"
Denied that Russia interfered in the elections, base on what Putin said, and not our collective intelligence agencies.... Putin thinks "I got a sucker."
So yeah, not surprising at all that the Russians want to help Trump.
