Sounds like a great idea...until China and Russia decide to attack the South.
Then its not such a great idea.
The north would join with Canada (and Canada being ruled by Communists would have them) and give us the three fingered salute.
It’s fun to imagine all the different scenarios. This time around it will probably be Blue versus Red states. The entire middle of the country against the fringe states on the two coasts. The Reds are better armed and more ready.
Just think—the New Red Army of America will be a band of conservative brothers and sisters!
Quite a switch on the last century.
