the damnyankee radicals of the HATEFILLED north wouldn't have accepted a FREE dixie on their southern border, any more than Iran will willingly accept a FREE Iraq.
BOTH sets of radicals HATE FREEDOM!
free dixie,sw
Well, you're consistent, if silly.
The cause of conflict would have been the same issue that had caused problems (and threats of war) for 40+ years before the Civil War actually broke out: the status of slaves in lands to the west. The Missouri Compromise, Clay compromise, and Kansas/Nebraska act were all failed attempts to resolve fundamental differences over whether new territories and states were to be slave or free.
Had the South won the Civil War, then the competition over slave vs. free would have been sharper than before the war, and a second war would have been likely.
The second war, like the first, would have been about the South's unwillingness to do away with slavery. That's just the fact, whether you like it or not.
