While the Allied Forces secretly assembled for intervention, the American Civil War continued unabated. If they knew that the victor would face suppression from the four major powers, I wonder if the North and South would still have the appetite for war.
Of course, this is just speculation. At this stage in the war, neither side has a choice but to continue fighting.
On the other hand, with the backing of the four major powers, even if they were to lose, they wouldn't be left with nothing, which I assume would make them more at ease.
At the start of the war, every country supported the Southern Government. When the Southern Government gained the upper hand, everyone quickly started selling armaments to the Northern government.
The war has dragged on precisely because everyone has been playing a balancing act between the North and the South. Otherwise, if the four powers had given their full support to one side, the winner would have likely been decided within the first year.
