I just learned that he apparently want to impose a new economic order on the world where every country basically becomes subservient to the US, but first they need crazy tariffs to make them all beg for access to the US market. I don't think it will work, and instead the global economy will move on without the US.
It has been always unclear to me how Roman Empire turned into that multitude of feudal states and microstates. And i lived through USSR collapse, and that dissolution of great central power is still hard to get a mental hold on - you live in one paradigm and somehow you find yourself living in completely different one, whatever was truth and crime yesterday, today became crime and truth, and i'm having kind of deja vu these days here :)
