i am most interested in the kind of system which would replace the UN.
if trumpism becomes the religion of the US i would bet on a chinese-lead free trade alliance and an US-lead protectionism alliance.
I can see an Alt-Right bloc led by Russia,UK, and the US with maybe Turkey (weird, right?) and India being all about bringing world peace by splitting the world up into self-sufficient ethnic enclaves run by some weird Santaneresque pseudo feudalism. The entire ultimate goal would be global stability through some weird Neo-Indo-Aryan global caste system which predetermines all disputes to basically anything.
I can also see Germany, China, Canada, and the parts of Europe that resist the Alt-Right becoming some sort of global bloc based on increased globalism and technocracy to the point their half of the globe is truly "run like a business".
That's where the world is going right now anyway. That doesn't mean we are close now or will ever get to that point, but it's not impossible within the next 15 years, and definitely not the next 50. I'd put it somewhere in the realm of getting people to Mars or having a computer wanting to be a person.
