The big issue really is the CSA never had a chance of winning. This overlooked fact will undoubtedly create a swell of controversy here, but after Chancellorsville, the South pushed upward toward Washington at too great a speed. They lacked foreign support for their efforts mainly because European governments questioned the likelihood of their success, and their economic viability in case of victory. The British leaders, for example, had already outlawed slavery, as well as most other major powers. The North had advantages in terms of both economics and transportation. An unlikely CSA victory would most likely have eventually been followed by some sort of reforming of the union because of economic reasons, along with the end of slavery, which was already becoming less and less monetarily sensible.
