This doesn't parallel US interests at all (at least not Obama's interests). Obama wants to remove secular leaders throughout the region and install a radical Muslim caliphate. That's why he tried to get the Muslim Brotherhood firmly in place in Egypt, that's why he took our Gaddafi in Libya and that's why he's supporting radicals against Assad.
That's my point.
Obama has, unilaterally, sided with the Saudi's and Gulf Arab states in the ouster of Assad.
Obama has not sought or received authorization from the US Congress for this policy, nor the means by which to carry it out.
He would not receive such authorization.
