Odds of a civil war in the near future?

I’m reading history of the US in the 1850s and it is sure looking like today’s news.

In the first Civil War, like today, the red states had the guns and military so you’d think they’d win. But the blue states had the manufacturing and that turned out to be more important from a military standpoint. But then the red states kept on fighting from within the US and that’s still going on today.
