I just read a pretty extensive analysis here:
It really opens your eyes at the enormous incompetence of Obama administration’s foreign policy in that region. It seems like there is utter ignorance in the State Dept. of the underlying groupings and ideologies in that conflict, combined with stupid arrogance of thinking they can somehow force the situation into compliance with US demands, even though there is no US leverage in the area anymore. Not even the small one that US used to have.
But then ignorance combined with arrogance is SOP with this administration, so no surprise there.
