When the Roman Empire collapsed, the dark ages, with its multitude of tiny authoritarian tribal states quickly followed. It took hundreds of years for societies to finally recover. And, the map of Europe was drastically changed. There is no reason to assume it would be any different today in this country.
I would agree. I think history is an excellent indicator and even without the example of history... just knowing how people are, this is exactly the way it would go.
I don't think this country would ever recover from that sort of thing and we would have several different countries, eventually -- in the place of the United States, each with its own laws (eventually) and it's own legislature and police and military... that's the way it would eventually go.
This -- if it happens -- will end the United States for good. It will never come back from that.
Daniel Webster put it this way:
Hold on, my friends, to the Constitution and the Republic for which it stands. Miracles do not cluster, and what has happened once in 6,000 years, may not happen again. Hold on to the Constitution, for if the American Constitution should fail, there will be anarchy throughout the world.
