The last Civil War in the U.S. had States banding together and separating from the Union.

The closest the U.S. is to a Civil War now is akin to a Cold Civil War with, for example, states gerrymandering their Representative districts. Or the Pacific states joining together for West Coast Health Alliance. Did I read rumblings about separate trade deals with foreign countries?

Protesters battling ICE in the streets would not, in my opinion, count as Civil War. Civil unrest? Sure.

EDIT: this always turns out to be one of my unpopular opinions. Oh well.
