Was just reading about the Ottoman Empire. Let's say the following happens
1 german final offensive does well in the west. But not to well
2 status que in the west
3 oe falling apart
4 Arab revolts are in full swing
5 germany keeps ukrain independent, and creates Baltic state dependent.
6 britan and France get the Arab states
So oe gives up the Arab states, but is compensated in Russia by gaining Turkestan and othe Turkish areas or the new ussr.
