My take is that Kim overplayed his hand and Trump just did what Reagan did with Gorbachev and just pulled the plug on the Summit and left. Kim got the message now and if he trult wants to come out of the cold then he will have to put up or shut up.
I think the plan of this summit is in plain sight. Trump kept saying he wasn’t concerned about a fast result. He knew this summit was not to reach a deal. We knew NK was concealing nuclear sites and this summit was to tell them we know. Trump said as much. When NK was not willing to give up those sites on the spot, the summit ended and NK will need to reassess its’s position.
Contrary to the silly Fox commentators drooling over the great “body language” etc, it was obvious something was happening behind the scenes. Trump was calm and in control, Kim looked wary. The president stated we confronted them about their secret sites. We did not expect a deal this time. As usual, the media is too mechanical to listen to what is being said.
Trump convinces Kim that the asshole US congress is trying to upstage Kim with the nonsense distraction and it would be better to disclose a deneuclearization at a Surprise event. Catch them with their D**ks in their hands and send them to the political scrap heap where they belong.
I know this is a dream, but wouldn't it be a truly NOVEL idea.
