Eh...
I get the points being made, but there's too much apples and oranges. Way more people, way more land, way more resources and geographical distances larger on orders of magnitude.
Despite what's going on, the U.S. looked a lot worse off and crazier back around '68, or the Great Depression or even the Civil War for that matter. "Never say never" and all that of course, but even when I feel worried I realize just how damn far we have to fall before we even get into the 2nd much less 3rd world multi-faction civil war failed-state territory.
And of course, we collapse Yugoslavia style, the whole world is going to be an absolute basket case.
