The Dotard's tweet was about China, not Rocket Man, and it was tweeted on 05/13/2018. Certainly more current than Schwartz' 1987 book. If I want to learn about the art of the con, I'll go to Dotard U. (I know, too late, all gone). Rocket Man plays checkers; the Dotard plays tiddlywinks; Xi plays chess. Don't get me wrong. I'm not rooting for Xi (or Rocket Man), but real estate con games aren't going to work on the world stage.
Back to Rocket Man, the Dotard may end up with a hotel in N.K., but that's good for him, not the U.S.
