Assuming a POD with the March Spring Offensive succeeding and the war in the Middle East and Caucasus going essentially historically until the Autumn of 1918 what would happen to the Ottoman Empire?
The war ends with them having captured Baku, but the Army of Islam was not very large and the Christian Caucasians want no part of the Ottoman Empire, while the Azeris have a certain desire for independence as well.
The Arabs are in Damascus and I would think the British would continue to support them with money and 'volunteers' for the next few years as well.
Germany would have other concerns such as securing their Pacific possessions, intervening in Russia and other defeated Entente states that may be on the brink of revolution I would think, and there was a growing conflict in 1918 between the Germans and the Turks over the Caucasus given that from what I understand, Enver Pasha wanted control over the region (and Central Asia) while the Germans wanted independent client states. Therefore I doubt the Kaiser would offer much help to the Sublime Porte.
Would the Ottoman Empire have had the resources and will to defeat the Arabs? Would they have been able to secure Central Asia?
Would the monarchy survive the next few years or could it be expected to be replaced?
