I think part of the problem with that is if states like CA secede, there could be scenarios like them welcoming in Communist Chinese warships into San Francisco Bay.
OK, then what happens?
Other than the shit hole cities, California is a great state filled with great Americans. Should California secede there would be a terrible California civil war, shit hole cities versus American California.
I think that you nailed it. The coming civil war will not last very long, because it will become an international war very quickly, with the commie side luring foreign communists into the fray. Mexican narcotrafficantes, sex traders for one. After all, just compare the American Commies to the Mexican drug runners, sex traders, and open border agitators. They are already THE SAME PEOPLE. And the American commies know they don’t stand a chance against us bitter clingers of 95% of the guns and ammo (and bibles) and all of us delporables. So a civil war quickly becomes a conventional international war. There are a lot of other commie countries who would be very interested to helping the American commies.
