If Trump and his group hoped that this kind of tough talk would make the North Koreans nervous, and make them come back with their tail between their legs — no, that’s just not the way they work. This is a stupid move. By pushing North Korea away, in such an in-your-face way, he’s pushing them to work separately with the South Koreans and the Chinese.

Timing the pull-out to the exact moment North Korea was publicly doing Trump a favor looked like an intentional burn. This was a slap in the face against Kim [Jong-un].
