A Civil War in the USA? Where would the battle lines even be drawn? There is no consensus, and there are hardly even blue or red states anymore beyond 60/40 splits. Even racially we are seeing a lot less polarization.
I don’t think a civil war in the us is possible but I think advertisers taking advantage of the divisiveness to see chaos is likely (and already happening).
Edit: I meant “adversaries” instead of “advertisers” but I think advertisers works equally well so left it in.
Clear, obvious initial battle lines are not a prereauisite for a civil war. The American Civil War, where the conflict was largely motivated by an issue which had a geographical split among subordinate polities was kimd of a special case.
