The U.S. didn’t enter WWII until after Pearl Harbor, so your point about Neville Chamberlin makes no sense. The best way to deal with N.K. is through sanctions, covert operations, and back channels — especially since they have nukes. Kim Jong Un is more than willing to let his country go up in flames if it means starting a nuclear war. Making threats that contain phrases like “fire and fury” only feeds Un’s ego and encourages him to continue acting recklessly. Trump appreciates none of this. He just wants headlines.
