With a Pod of 1880 or later, have the area covered by OTL Saudi Arabia ruled by two or more factions that are hostile to each other (either cold war, truce, or "we have bigger enemies to worry about" situation), and unfriendly to non-Arab and non-Muslim powers (incl. Britain, France, USA, China, India, Japan, and Russia).
The exact status of other Arabian peninsular and former Ottoman territories is open. However, if the Ottoman Empire is a major power, then none of the major powers replacing OTL Saudi Arabia Arab powers should be politically close to the Turks.
