I believe that the US only has one real ally in the Middle East, one that would let the US use its resources (i.e. miliatry bases) unconditionally because of the support (financial or otherwise) that the US gives them.  And they require such an ally in the Middle East to stop the Arabs states from pulling together and becoming a force to be reckoned with.

That Ally is Israel!!! ANd hence the US stands by while Israel commit all these atrocities!
