Lets see, a bunch of South African racist travel back in time and arm the South with automatic weapons. Then … no wait, that was Guns of the South, by Harry Turtledove :)

Good book, by the way.

Had the South won, I don't think the CSA would have lasted long. It would have become like Europe and the States would have fought each other. Eventually, they would have all come crawling back to the USA and joined America.

Texas, on the other hand, might have opted to become a Republic again. Eventually we would have probably joined America too.

I am glad the North won (That should get me lynched by my fellow southerners)
