it will certainly do something in the coming few decades. i don't think it dissolves in any territorial way myself, and i say that mainly because of the natural advantages North America gives for food, climate and security.
it will however burst in terms of the current form of government, the de-industrialising food/commerce a bit, and i could go on and on. lots of this is global no doubt and will have its own flavor in the US. I think once done, with lots of violence sadly, the US will come back quite strong. but i am seeing that as being after our lifetimes.
the US to me is the "free-ist" place on earth over the last era (oil/internet). that is great and all but just comes with a massive "social coherency" tax. you motherfuckers are way artificially angry at each other. deep, deep division exists, along with some pretty big holes in EQ. my 2 cents.
best thing you can do is try to be positive and live every moment best you can. ya'll homies be good now.
