Absolutely. These are International negotiations, Kim can't look like a push over/ has to be able to save face in order to remain a leader, and the number one rule in negotiating is that you have to be ready to walk before you even sit down at the table (which POTUS knows better than anybody). Look at how many times during this "dance" they have cancelled then rescheduled. POTUS said a long time ago that this may take several meetings and/or summits. This is all "in play"... sit back and "enjoy the show" - "nothing can stop what is going to happen... nothing".
