Jack Durish's answer to Why does everyone think that during the Second Civil War the gun owner...

I'll start by saying bluntly that I do not believe there will be a "Second Civil War"... and adding that I'm very glad of it. Speaking hypothetically, if one "did" occur... I think it would look something like this: a radical shift in national politics would result in sporadic, but serious civil unrest. Forced to respond, the federal government (or those of individual states) would declare limited martial law; anyone, regardless of "side" would then become a "threat" if armed. Somewhere, "something" very bad would go down... and suddenly, there would be division among LE and military (whether reserve, guard, or active) as to how to respond. As the economy and civil infrastructure collapsed, it's possible that the government itself would split, with various agencies and entities "picking teams" based on pre-existing, underlying, motivations. At that point, you "may" have an actual "civil war"; though I believe it would look more like a coup/counter-coup, with local support falling in line behind their faction(s). Rather than pitched battles, there would be attempts to hold important areas met by resistance. The Military would probably be working towards some sort of cease-fire between their forces almost immediately, with most strategic assets falling solidly under control of whichever "side" managed to "sell" itself as the "legitimate" government. There would be individuals; politicians, noted personalities, wealthy people... who may try to form their own factions, entities, or forces. These would then form an ad hoc, and competing power to whichever factions within the original government were vying for power. Ultimately, private individuals would also seize the opportunity to break away from broader state and federal affiliation... likely taking matters of security and justice into their own hands. The resulting mess would be a modern mix of feudalism and mob rule, with both "formal" sides unsure of where they stood. As these either mended their fences, or one gained superiority... it's very likely foreign "assistance" would be considered to bring the "independent" parties back in line. This would undoubtedly come with many strings attached. This would force the independent "bands" to join forces, possibly with the "loser" of the greater political conflict. At that point... you'd probably see a true war; replete with strategic and tactical military assets, veterans, LE, and private "volunteers" all rolled into one. Such a fight may even progress into a second revolution, or "world war". Thankfully, this can all be discussed academically.

Collapse then Civil War. I ask, "Did you ever read any of the history from the Civil War in North Carolina about, "The Shelton Laurel Massacre"?
