The De Bunsen Committee's suggestion for the devolution of the Ottoman Empire following the Great War was not takes as a policy by the Britain and to an extent its allies for the restructuring of power in the Middle East. Instead the Powers went forth with the mandate system that as we all know utterly screwed up the region ofthe Middle East.
This calls for the decentralization of the Ottoman Centralized state into a federalist system whereas, though the Entente would take snippits of OE territory but the large majority would have the restructuring which would include four basic "Eyalets" or states which were Anatolia, Armenia, Palestine-Levant, and a Jazireh-Iraq (Arabia+Iraq). I suppose this is sort of like a Ethnic System, not unlike the Yugoslavia, where it seems that the Turks are here, Jews-Palestinians here, Armenians here, and Arabs there.
The set up would have given Turks control of Foreign Policy matters and Britain would have helped correct flaws to the modernization proccess within the OE as well as allow the Turks and various peoples help themselves.
The Brits would be in favor in that it would require less military prescence on their part in the region. This could allow for a Yugoslavic situation or allow the Middle East to pan out more naturally.
Would the problems of the Middle East be as similar as they were today?
