Things are happening mighty fast. I’m suspicious.
The things that count occurred last October 10th.
A couple hundred Nork nuclear techs were in a test tunnel preparing some kind of extravaganza that was supposed to scare the world when the tunnel collapsed, killing them all.
A most convenient earthquake.
It probably had some help. And Kim Jong-un figured out that earthquakes like that could target him next, without warning and with no way to defend against them. And around that time someone let him know that he could give up while saving face, or he could lose the hard way. Art of the deal. At least that’s the story some are saying explains Kim’s sudden change of heart.
