I have long wanted the USA to become less powerfully dominant in the world. Certainly the spluttering results in Ieraq, Iran and now Syria show it to be less than an all-conquering military force, and now erratic behaviour vis-a-vis treaties is showing it to be an ally you might never want to rely on. I think the EU is becoming aware that the USA cannot be seen as a country to be counted on, and Chin, with its road-and-belt proceeding apace, seems pretty comfy with a world where you can thumb your nose at the USA.
So I can only agree with Bom. Bob that more of Trump will deliver what Trump is already delivering: a USA hurting because of tariffs and thus economically weaker, trade wars that make many countries start to look around for new friends, and so on.
