That's a pretty silly map.
It only confirms that this is a prediction coming from a guy who knows nothing about the US at all, except which ends are closest to the other countries/continents/unions he names.
Montana, and Wyoming, as bastions of Right America, would never party with the socialistic likes of Canada. Colorado has way too large of a hispanic population these days to not join Mexico, and same with Nevada. Utah would likely isolate itself from everyone, since they're just that different. There's a few problems I see just off the top of my head, I would dissect the whole thing, but it would continue the exercise of pointless, meaningless speculation, and a silly exercise in stereotyping by state (which is kinda fun!)
There's no indication the US will splinter any time soon. Simply no reason, no fomentation, no motivation...whether we'll someday fall as the supreme superpower, now that's a different story!
