In every negotiation, someone has upper hand. Can go back and forth. Right now, KJU has upper hand, as he has POTUS in position of trying to preserve summit. POTUS is better off sticking w/ 'Rocket Man' & max pressure policy rhetoric.
I agree the U.S. has leverage overall but, regarding the summit, not if POTUS wants it more than KJU...NoKo still has nukes the charade w/ blowing up the mountain doesn't mean a thing. We have no inspectors in there & he still has a nuke program.
