I think there is a decent chance that the US will break into smaller pieces.
I agree. This is a huge country. We have folks from New York City telling guys in Waco, Texas how to live their lives. I do not see our current political system sustainable. But what will happen? Hard to say. Ultimately, I think we'll see states like Florida and Texas become their own countries.
More likely to form a southern states bloc which would include Florida, Texas, Louisiana, Georgia, Oklahoma and perhaps Arkansas. That actually would be awesome.
