Despite my opposition to President Trump, I have to admit the possibility, the likelihood even, that he will have one or more achievement to his credit by the time his term ends, or perhaps only identified sometime after the end of the term. He is disruptive, usually distructively so, and a change agent, though not as much as advertised. But doing things differently is not always bad.
I don't know what the achievement might be--Mideast progress maybe? Or maybe the achievements will come in the next President's time, when she is able to reconstitute some bureaucracies (State, EPA...) in a more rational form after Trump's appointees have blown up the old?
