Ok thank you, let me also draw up a more elaborate response. Note that I am also very much an outsider to the US (as I live in Europe).
Regarding Korea, the fact that North Korea makes a wild threat (e.g. to attack Guam) and then doesn't follow through is not a deescalation; this is how NK has consistently behaved for decades. Indeed, the situation around NK is more tense than it has been in a long time, and shows no signs of calming down. There is clearly no deescalation here. You have an interesting point about China though; China so far seems happy to do favors for the president. Of course, he has also done a lot of good for China, which leads us to...
...trade. Now obviously, stepping out of long-standing trade agreements (and starting trade wars with traditional partners like Canada) is the exact opposite of "sustainable trade". Effectively, this paralyzes US trade while they take time to re-negotiate, and in the meantime the obvious effects are (1) unemployment in the US will go up sharply, and (2) other countries will have more trade opportunities. Notably, this includes China. It is very good for the rest of the world that the US becomes a less competitive trading partner; it's just not good for the US.
And the whole Dow Jones thing is just a red herring. Yes, the index is up, but as the article I've linked explains (1) it is not a measure of how well the economy is doing, but of how much rich people benefit from stock options; and (2) politics has a very limited influence over these indices, particularly in times where congress is gridlocked. After all, fixing the economy is slightly harder than tweeting about it...
