To learn about the only problem with Trump that matters go read these direct quotes from the transcripts reporters kept while he was flying to Paris the other day. They're scary as hell. Not only does he know nothing about policy or human nature or history or anything else he is incapable of learning. He lacks the capacity to "bone up" on a subject. He is not interested in the least in anything but what he can brag about. So all the other jabber or attempt to take an angled look on what he says about North Korea or anything else is ridiculous. You'd get better guidance from a crystal gazer in Arizona.
