So with a POD from 1910 (with World War I stil starting in 1914), have World War I be a stalemate in both the East and the West. France stalemates Germany in the same area as OTL, while Russia stops the Germans and Austro-Hungarians in Poland and Carpathia. The Entente try to push into Germany and Austria-Hungary proper, but still there is a stalemate. The war ends in 1918, with a status quo ante bellum (or as close as possible to that, without a Versailles-like treaty ITTL).
Bonus points if Italy is neutral and the Ottomans still declare war on the Entente.
