This one’s probably not going to happen. I would assume the fracture of the power of the American state would allow for a power vacuum to form. I would further assume certain polarized demographic bubbles in the US wouldn’t feel confident allowing the legal government of the United States to govern them.
From these assumptions, I think it’s possible but unlikely that North America will see a rise of warlords. Perhaps this could be like China’s warlord era, or perhaps it would be unlike anything anyone’s seen before - who knows? Regardless, I’ll reiterate, probably not going to happen.
That’s not going to happen. Why would there be so many splits?
It’s not the states that are squabbling with each other, it’s two groups, so the most plausible is a “split in three” scenario and only because there’s democrats in the East and democrats in the West, but few in the middle.
States do squabble a good amount, especially over energy, water, utilities, taxation differences, cultural differences… but yes I agree this isn’t too likely.
