What happens next is that history resumes and globalization ends, because it's the US that's been enforcing peaceful globalization since 1945. Borders are no longer sacrosanct, more countries fight each other, a traditional empire or two maybe get started again out of necessity, and countries dependent on imports for oil and food start having major problems. It works out ok for the US though. We get inflation and all kinds of shortages for a while, but manufacturing moves back. We have no trouble feeding and fueling ourselves, and no worries about invasion. In a decade we dominate the world even more, because most of our peers fall apart. But it won't be much fun for a while, and for a lot of the world it'll be seriously grim. I'm not necessarily saying it's the moral obligation of the US to police the world forever, just because it was in our strategic interest to do so for a while. Maybe we should do what you suggest. Just saying, be aware of what it really means. It doesn't mean world peace.
