The North Korea thing is just for show anyway: Anybody with an IQ over 60 knows Kim will never give up his nukes. The lesson of Ukraine is not lost on Kim. Everything else is just meaningless play-acting. We can improve out relations, but forget about the nukes. They are here to stay, and if Trump fixates on them he is going to be disappointed every time they meet.
This is a case where "alternate facts" and a "personal relationship" have no effect on reality.
