China and India area already in open conflict/deadlock over natural resources right now. That's only going to get worse. Russia continue to rattle the sabre, but knows that any conflict with us leads eventually to an ass kicking that probably turns nuclear. Unfortunately, I agree to a degree on the USA. Unless moderates retake control of the country, we are in serious trouble. The idiocracy is real.
China's still got it's own internal issues. Will be very interesting to watch how they navigate those issues. A few are their healthcare system was way more woefully unprepared for COVID than we were and it showed with draconian measures being put into place and China just stopping reporting numbers. No one got hit harder than they did and there is some speculation of millions dying over there.
Also, China has some infrastructure issues that may come home to roost. I know a bunch of us were laughing about the Three Gorges Damn. Still, it took some structural integrity damage during the flooding that can't be fixed easily. Especially not in 1 year. If a similar flooding situation happens next year, they entire flood plain is in serious trouble.
Could post about this kind of stuff for hours.
