That's right, but also consider other countries. Its pretty normal for militaries to be running the show, and extracting rent at every possible juncture. When that rent is harder to get, they'll fold. IMO, the more states, the better. Existing big states will break into a thousand pieces, and maybe even without a fight - but even if there's a fight, it'll be a lot easier when the opposing military can't pay for itself.
I actually expect this to make the US even stronger, at least at first. It'll keep us relatively strong during the period of deescalation. The reason is, there's actually reasons to be pro American. We have ideals, and politics still hasn't erased the ideals crystallized into the Constitution. What country in Europe can compare to that? They're retarded, and they'll all split up because nothing holds them together beyond force.
