So I was watching some old shows that I TiVo'd yesterday and one show had a interesting possibility. During World War I the British, got the Arab tribes to fight agains't Turkey and Germany, by promising a massive independent Arab state after the war stretching from Syria all the way to Yemen (Syria, Iraq, the Gulf States, Jordan, Saudi Arabia, Egypt, Israel, Yemen, Oman, Lebanon) but they ultimately split the Arab lands up to the present day borders. So could this have ultimately happened, the British went back on their promise because they didn't want one power in control of the worlds oil, (not the world oil because the US was the world's leading oil supplier I think) but if the Arabs really wanted it could they have gotten their wish and if so how would that effect the geopolitics of that time period.
