I am currently considering writing a TL about World War One with the pod in early 1917.
The idea is that for whatever reason the July offensive does not take place instead the Russians overrun ottoman turkey in a Caucasus offensive, then they make peace with Germany in later 1917 giving them Poland and Lithuania.
What I'm really not sure is what the central powers would do next with essentially an early Brest litovsk and many more troops, but losing the ottomans.
Go for the knockout blow against France, was that achievable?
White peace?
I would be thankful for any suggestions as I'm not incredibly knowledgable about the western front.
