Probably because unlike Trump they are diplomats that are trying to bring a bit of piece to the World. Cheers!
Maybe they should have been Joe 6-pack diplomatic and as they were walking out tell Trump that they have a little something for him before they go - then pull out middle fingers from their pockets. I think partly because of the Kimmel thing the world is seeing Trump for the wanabe dictator that he is - and the free world will be giving him the finger. Cheers!
