The Big Bad Wolf.
The nation has become so divided that each side will not accept government by the other. It will not remain locked in positon where each side is dedicated to preventing the other side from moving forward forever. At some point it will have to break apart.
Been there..done that.
The next time..no reconstruction.
The difference is, this time it won't be state against state. This time it will be an eruption over the whole of the nation. Your preview isn't the Civil war, it's Syria and what's coming in Greece. You might regale yourself in some past glory, but those days have come and gone. The nation won't break in TWO, but break apart, much like to Soviet Union did. We aren't dividing along clear lines of slave v. non slave states, but dividing into tribalism with competing fractions.
I expect that some portions of the nation will become protectorates of stronger countries who already have interests here.
Well..that would be part of your conservative fantasy.
But it ain't going to happen. No matter how much you people try and make it so.
