It's been 2 weeks, I don't see the point of declaring partisan victory.
There was almost certainly some back channel stuff going on. Rhetoric is an afterthought. If I had to guess, NK and US reps met, perhaps through an intermediary and agreed to ratchet their actions down. This freed up both sides to yammer their nonsense and bellicosity to the credulous. I would suspect we asked for no missile launch and they asked for the "command only" nature of the August joint military exercise to be loudly proclaimed by us to be "routine annual changeover" calibration and to move no hard military assets, all of which happened. The yammering class can focus on the rhetoric but the thinking man should focus on the details that made the deal. President Trump and Kim can play to their audiences by continuing their blather while the real diplomacy happens. There was probably an explicit discussion of continuing bellicose rhetoric by both sides in the same way that President Trump told the Mexican President that about the wall.
