Nobody is going to die to keep a state in the union.
I didn’t say secession was a hostile act. I don’t believe any state should be forcibly kept in the union. My response was to someone who postulated if an independent California started to make warlike maneuvers against the U.S. by aligning with known and dangerous enemies and bringing in gang members en masse as some sort of mercenary force. That would have to be dealt with and swiftly.
