I'm assuming you are talking about the American Civil War. There is still a certain level of racism in the South that was heightened by the Civil War and the Southern economy is not as good because they are still behind industrially because they relied so heavily on cotton around the time of the war. Also punishments from Reconstruction and the increased industrialization in the North that occurred as a result of the war has and will continue to hurt the South.
No one, not even he could have averted the war without a historical wrong that could no longer be justified in a democracy - the continuation of legal human bondage in the United States. But to answer the question. Yes, I think it was very possible that no guns had to fire, and it would have been to me a revolting development.
