So, this is something I've been pondering for a time.
Let's say post World War One, Britain gets Syria instead of France. Would they promise Abdullah of the Hejaz Syria as his own Kingdom to rule as a thank you for aiding them against the Ottomans? If they did, how stable/long term would Hashemite Syria be? And secondly what changes in the region as a consequence? Does Faisal still get Iraq? What would the French get if not Syria?
