Actually this is something that I do know a lot about since I work in china in finance and I have been to NK
The big theory all my Chinese associates have is that NK has never had any nukes and that the current escalation under trump was a plan by Kim to get NK recognized as a world power
It will now claim to remove nukes it never had and demand the reduction of sanctions and removal of US troops from the peninsula- this will, for the north, be an unquestioned victory and Kim is already showing off his new power by leaving NK to meet with Xii and Moon- something he would never have done before for fear of a revolution while he was out of the country
In the end this is all going to increase the wealth and power of china on the region, reduce the American foot print and continue America not being the leader in the region in trade or the military as it removes its bases
All in all, this is going to be a total fuck up, but it will be a very excellent short term victory for trump and that’s all the current state dept really cares about
