Is there any way for a reverse of OTL to happen in Arabia? A scenario where the Kingdom of Hejaz conquers the Kingdom of Najd, resulting in a kingdom of Hashemite Arabia? How would this effect the oil politics of the middle east, with a country that rules both Iraq and the Arabian side of the Persian Gulf? Would the defeat of the Saudis butterfly the rise of radical islam?Would Israel still be founded? What would relations with Iran be like? Would it be seperate kingdoms, or one big one? Would the Hashemite monarch be overthrown as per OTL everywhere except Jordan?
