From what I understand, source uncorroborated, that Rocket Man was in some danger and those charged with protecting both Kim and Trump decided that they should call it a day until the danger had been dealt with.

It's tough at the top. Kim had to show the NK hierarchy that he could be more ruthless than his father to gain credibility as a young, inexperienced leader. He must maintain credibility for his strength if any change is instituted. I think Trump has an appreciation for Kim's dilemma, and is willing to give him the breathing space to gain the time to work through the details of how to improve things without risking sabotage from within his own military "nobility."

Hopefully, Kim will also gain a sense of urgency, and recognize his best chance for a fair deal lies with Trump, and will arrive at a mutually beneficial solution before the 2020 American elections. I doubt a full denuclearization is in the cards, but an agreement on a limit of nuclear weapons sufficient for the defense of North Korea could be an outcome. The hermit kingdom isn't about to risk full exposure of its population to international tourism, but expect small bites of entertainment centers sufficient to significantly increase their GDP and smooth the transition over a generation or so.

I think given the history of north korea, it is their belief that nuclear weapons are the only thing that can guarantee the survival of their dictator regime. And they are right !! Given that, I think the stance of the USA should change.
1) Immediately end the "korean war" with the DMZ as the dividing line, and offer that the USA will not attack the north korean regime so long as they do not attempt offensive operations at other countries.
2) Allow them to have their hoard of nuclear and other weapons as their safety net, so long as they do not threaten or launch attacks against other countries, or sell those nuclear weapons to other countries.
3) Offer to normalize trading and travel relations with north korea to the extent that they feel comfortable.

Forget the idea of North Korea just giving up their nuclear weapons. It will never happen with this regime in power.

Hopefully, Kim is trying to see how far he can push and this is hardly over yet. Time will tell.
At least Trump will never do what Clinton did or fly over a multi-billion dollar cash bribe just to put on a something for nothing show.

The Art of the Deal is right near the top of my reading list. Haven't gotten to it yet. Finishing a book on options trading, then "Rules for Radicals", then this...

I heard this days ago.

Never mind, the MSM treats the encounter as a failure, gloating over the president's "inability" to get a deal with Un.

They were trying to influence the optics by scheduling the Cohen hearings for the same day and won't let it up by reporting facts now.

The president did the right thing by walking away. Shutting down ONE nuclear facility in exchange for lifting sanctions in totality was a bad deal.

I don't see things as blown up at all. It never hurts to ask. If I were Kim Jong-Un, even if I were the person I am now who believes in liberal democratic republics, I would be trying to initiate reforms, but I would never have any intention of relinquishing all nuclear weapons. They're just too good to give up. If I were President Trump, I would ask for him to relinquish all weapons with the plan of accepting relinquishing high-yield weapons and long- and intermediate-range missiles. As Trump said, you have to be ready to walk. When I go into an important negotiation, like for a rental contract, large job/project, real estate purchase, I mentally imagine myself walking out. It's not so I can be hardnosed, but it's to keep people from taking advantage of my desire to have the deal done with.

So the outcome seems very ordinary to me. With President Trump, we often see attention-seeking clown antics, but nothing about these talks seemed that way. It seemed like he did exactly what he should do. I think we take the threat of nuclear war too lightly today compared to when I was a kid. It seems like in this case Trump is taking it with the appropriate seriousness.
