Is that an official cia statement?
No matter what, CIA must've revealed a method, like the Turks did when they claimed they had a video. But then, it's a Game of Thrones on a very important country so it may be worth it. Maybe we'll keep the oil cheaper for a few years ;)
I have no love for the Saudis, nor many of the other countries over there, though. I tend to view it as Game of Thrones material for a foreign state and I hate it, but figure that it's really none of our business.
