The will be no Civil War. There is not enough widespread guts left to fight one. There is nothing equivalent to the Antebellum south infrastructure to support one. There may be some more violence, but that is about it.
The Antebellum South didn’t have the infrastructure to support a war either — that’s why we LOST! But, the times they are a changin’.
Keep your powder dry! ;-)
All that could be done now against the modern army would be guerrilla warfare and that is the fantasy of militia kooks and isolated nutcake killers like Tim McVeigh.
