Hello,
I see it argued all the time what would have happened if the South had won and if some general had taken a left turn or eaten an apple for breakfast (although less lately I'll concede)
However I haven't seen yet a thread about what would have happened if the South hadn't fought. Listening to one of the latest Askhistorian podcast it seems like it's a very political problem, and political problem can be worked out.
See how WWI was adverted several times before actually erupting at some point.
