None of these apply. Not one of the other country examples given contains a heavily-armed populace. A U.S. collapse will be very different.
The most powerful country in history, both in military and economic might...
The wealthiest poor/dependent class ever in history...
The best armed citizenry in history...
There are a lot of firsts. The collapse of the USA will not be isolated. The world is going down with us.
I have always felt that any future American Civil War Redux will most likely make the first look like kids play. You want to see what very likely could lay in America's not to distant future; just go back and watch reruns of the nightly news stories on the break up of Yugoslavia. You can amp up the violence about 10 fold, too.
Instead of wanting to break it apart, both sides want to keep it together, with their ideology in place. After the fact we will have one of two countries taking the current US's place in the world. The first is a Constitutional based republic where every man has an equal right to try to succeed, with minimal government interference. The other is a Socialist dictatorship, where one can only succeed as far as the ruling political class allow them.
If I'm around, I know which one I will strive for, and which one I will do what ever it takes to keep from coming into existence.
