The rest of the world seems to have viewed Obama quite favorably. Less so for Trump. American influence is accepted, not imposed. Obama is a better envoy for American power because he exudes the illusion of choice. Obama is a better politician...like it or not.
Obama's presidency was largely a placeholder. He wasn't one of the greatest presidents, but he wasn't among the worst either. He was basically a darker-skinned GW Bush. Conservatives love to scream about how he pushed the conversation to the left without acknowledging that Obama, SJWs, identity politics and the like were simply the harvest of a long-ripening crop. We are now reaping the fruits of political seeds sown in the 1990's.
In republican terms...He got his. Don't hate the player, hate the game. The new guy promised he would drain the swamp. And he has...right into the west wing. The rest of world sees that, too.
