First there was the Carter Doctrine on ME oil as exclusive province of US interests and outside powers' interference was forbidden
Several administrations later, the ME is blessed with an addendum that deals with internal ME meddling with US interests.
So to make a story short, here's a concise New Middle East Obama policy. We support "our" bastards (dictators) who are sophisticated enough to beat, arrest and kill their own people in the low hundreds (Bahrain). We get slightly annoyed by "our" war on terror collaborators who crudely beat, arrest and kill their own people also in the low hundreds (Yemen). We're strongly inclined to ditch our support for unreliable, Iran-aligned dictators who beat, arrest and kill their own people in the high hundreds (Syria).
We unleash war - via the North Atlantic Treaty Organization as a weaponized arm of the United Nations - over unreliable oil-wealthy dictators who beat, arrest and kill their own people in alleged thousands (Libya). And we remain absolute mute about "our" monarchical bastards who pre-empt the possibility of democratic protests (Jordan, Morocco, Saudi Arabia) or invade their neighbors to smash ongoing peaceful protests (Saudi Arabia).
