Those who pretend to tolerate him do so because he does their bidding as he unctuously sucks up to them. They like that. He, being unaware, does not realize that is what he telegraphs each time he tells us how much Kim likes him and how much Putin and he get along.

They will tire of him and when they do well they'll just dump him and move on to someone new.
