Well, I'm doing TL research, because all my past ones have flopped for various reasons, and I came to the realization that every single thread we ahve (or that search finds) about the US not joining WWI have the CP winning or stalemate, or at the very least were dedicated to that line of thought before being derailed.
So, let's get some discussion in here on how the Entente could win, or even if you think no strategy change is needed, how much longer it would take. Also, post war treaty discussion would be interesting too.
