I think what you are saying is total nonsense.

It's not because he is black and it's also not true that he hasn't done anything. If it is enough is debatable and he himself says he doesn't deserve it but so far it looks like he's seriously trying to fix the shitholes left behind by the previous presidency, nationally and internationally.

He started the dialogue with Cuba and North Korea again, he stopped the missile shield in Eastern Europe (which takes a lot a friction out of the regional conflicts with Russia), his policies are directed towards peaceful dialogues as means to resolve international conflicts,... and the two current wars weren't started by him. Suddenly backing out now won't solve anything either.
