No, we don't buy our water from the Turks, we actually sell it to Jordan. The mostly dry area you mentioned is the Syrian desert, Uninhabited.
Before you start considering cutting the water supply of the people as a solution (or the Euphrates river if that's what you meant?), why don't you think about stopping Russia and Iran from selling tanks oil to the regime first. Not to mention the billions of ammo and all the missle systems, thanks a lot Potin!
BTW the reason we don't have a leader is that it all started out as a peacful people revolution, when you fight for freedom everybody becomes a leader.
