So like, I have these 'what if' things popping around in my head from time to time so I figure I'll just post them when I think of them and see what (if anything) comes out of them.
What if the Germans had not sunk the Lusitania in May of 1915? Would the US still have entered the war on the side of the Entente Powers or the side of the Central Powers? Up until that event it could have gone either way.
That's something I always found really interesting.
