Doug says the problems are all bubbling to the surface…and when the U.S. eventually breaks apart "it will not be peaceful." (If you missed Part I, you can catch up right here.)

Justin: What about political tensions? Because, as I'm sure you've seen, the far-left and far-right are becoming more and more antagonistic. In some cases, they've even become violent towards each other.

Could radical political ideologies cause the country to break apart?

Doug: Yes, I think so.

In the late '60s and the early '70s, hundreds of bombings took place at universities, banks, and all kinds of places. The National Guard was in cities like Detroit during the riots, and they were raking buildings with .50 caliber machine guns. It was wild.

I don't think most remember this. At least, I don't see it being brought up anywhere.

I lived in Washington DC then. It seemed like there was tear gas in the air half the time I went out on a date on a Friday or Saturday night.
