The Ottoman's involvement in WWI was highly circumstantial and came down to British blunders over the deliver of two Dreadnoughts ordered by the Ottomans and a weird naval chase of two German ships in the Mediterranean. In hindsight, a slightly less bellicose British policy might have induced Ottoman neutrality.
Let's say the allies do much better in atl because the Russians have access to trade coming in through the Dardanelles and the Germans/Austrians worse. The allies are clearly winning by 1917 and the Ottomans jump on the allied side for self preservation and to nationalize (loot) German assets within the empire when the Germans looks knocked down.
Let's further assume Russia is wobbling and wrecked by political instability by the end of the war due to its costs and isn't a geopolitical threat in the immediate future. In this tl, it's hard for France/UK to justify partitioning a recent ally's territory. How does the Ottomans do at this point, do they fall to an Arab nationalists revolt which was otl instigated by the British? Or does the sick man of Europe keep chugging along without a major war to destroy it?
