That would seem pretty plausible. The Saudis are the force that is mostly energizing the Syrian rebellion with money and weapons and working to move reliable jihadists to Syria to provide leadership to the rebel fighting units. This is being done with the knowledge and assistance of the US . The same thing is happening in Iraq where the Sunni militias are being flushed full of dollars and new jihadist fighters. There is a sort of logic here. In both places the goal is to thwart Iran. In Iraq the idea is to put in place an armed force capable of taking on the Shia militias and thus cut a good bit of the ground out from under Al Awalaki, who is seen as mostly an Iranian stooge. This will keep Iranian proxies from dominating 2/3 of Iraq. In Syria the goal is to topple the Assad regime and thus dispose of Shia Iran's only ally in the Arab world. Once the regime falls it is necessary there be a somewhat reliable Sunni armed presence to checkmate any Hezbollah-Awalite resurgence in Syria. If Syria lapses into years of armed chaos to bad it is their problem not ours. Such an even will also eliminate the Iranian's only foreign naval base at latakia. The Iranian navy is a joke today but the clerical regime has earmarked enough funds to make it gradually be a real blue water presence. Beyond that the latakia operation base is a great place to quietly put in place the materials for equipping several Iranian Q ship type vessels that look like freighters but really carry some sort of EMP weapon system. This is far or at least mid range in the future but it is a definite plan of the Irainians for developing asymmetric military capabilities.
Stevens death appears to be as a result one of those incalculable bits of inter Muslim plotting and scheming. Some group of Muzzies got cut out of some deal and felt they were ‘dishonored’ so that cooked up an appropriate (to them) revenge. Arabs will do these things even if it damages their direct interests. For them just like black street thugs ‘honor’ is everything.
