Trump is pissed off as it is undermining his influence over S.Korea. he wanted the big stand off with N.Korea with them ultimately standing down. They’ve pulled the rug from under Trump and gone directly to S.Korea so Trump might see that S.Korea has gone behind his back. He’ll spin it to his advantage though. All good in the end, whatever works for the people at the end of the day, but it would be nice to see the regime collapse in a movement driven from the people like with the USSR and East Germany, but I don’t think the N.Korean people are in the same position to do that.
I suspect it won’t last though. What’s the end game? The N Korean regime is not going to have a change of heart and back down and the country re-unified. I suspect after the Olympics business as usual will resume.
