One impact of this is it will likely come up in the debate and it will be interesting if there is a detailed question on the strategy and the coalition. Trump may be able to bluff his way through but I doubt he knows Peshmerga from Pierogi. The situation in Yemen and the US Navy may also come up. Again another complex situation that may be hard to bluff through.
He won't even bluff. Twenty seconds on topic and then attacks on other subjects. What will destroy him is if Hillary and the mods hold thr fire on him. I have no doubt Sniffy can go to to great lengths to avoid looking stupid, even if it makes him look ten times more stupid.
