I'm sure there are a billion threads on this so direct me there if you like.
I seem to recall some thread on The American Civil War sparking a World War type thing, but I was thinking more of a scenario in which the American Civil War breaks out just after (or even as a result of) the first shot of such a conflict.
At any rate, I'd like to hear some possible PODs and some discussion on possible results.
Go ahead. Make my day.
