Last thread it was "stalemate" this time "co-exist", but neither is accurate.
In fact, what the Confederates wanted was to grab off as many USA states & territories as possible.
In addition to the original eleven CSA states (one-third of all USA states), Confederates claimed two more (Missouri & Kentucky), sent Confederate armies into five more plus two territories (Maryland, Pennsylvania, West Virginia, Ohio, Indiana, Oklahoma & New Mexico) and ran guerilla operations in at least four more (Colorado, California, Kansas & Vermont).
Bottom line: what you call "co-exist" or "stalemate" Confederates wished to achieve only after they had effectively destroyed the United States.
You are an idiot. From minute one the CSA was in survival mode. The USA, while fighting a war in the South, built and equipped the largest Army in the world, managed to build the inter continental railroad and the westward expansion continued unabated. There was no threat to the USA, ever. It was just smaller but still expanding and getting more powerful day by day.
