I don't know...
If you look at the pattern of behaviour from the US in the Middle East, the common outcome is the destabilising of independent regimes. Is this an accident of management, as it is typically analysed? I doubt it, they want change in the way these communities are managed, ideally with a government that complies with US interests. The constant fear and stress of war will no doubt make the population of an area amenable to just about any change; alot of things would seem preferable to uncertain survival, uncertain conditions and the grieving of even more lost friends and family. War removes structured civilized values and returns everyone more or less to kill or be killed type of living; you cannot rely on food supply, water, housing, medical services, police, roads, or anyone to help fix or maintain any of these services and infrastructure. And you can expect desperate and unscrupulous people to rob you of anything you do have.
The US really wants to get control of this region, but they want total chaos to fatigue the population into accepting it. They don't want desert nomads who exist outside the "system", they can't work with self-determined existence. Those nomads, what a bunch of anarchists, eh?
