I think his foreign policy has been spot on so far. He has leveraged the US into a positive position on trade, strength with our adversaries, and with our allies in the case of NATO. I was no Trump fan at the start, but he has done a great job at home and abroad.
I am not sure what you are talking about when you say the divide of the USA unless you are talking about the unhinged Democrats...that is not his doing, there is no repairing a divide with Socialists.
