The House of Saud pretends to be our friends, and takes our goodwill and funnels it to fund Wahabbism. They keep their friends close, and their enemies even closer.
There are some 3,000 "Princes of the Blood" who are the top dogs in the KSA. Each has a business advisor, usually, would you believe, an Iranian. The KSA is run like Tony Soprano runs Northern New Jersey. Every Prince has a piece of the action, a crew, and a territory. There's a Taco-Bell Prince, a McDonald's Prince, a KFC Prince, a Ford Prince, a Mercedes Prince. One hotshot Prince runs the Navy. Another the AF, Another the Army, another the National Guard, another the Religious Police, Another the Intelligence Service, the Phoneco, yadda yadda yadda. ... none of whom are on the same page, but somewhat coordinated. Underneath the Princes of the Blood is another club of minor princes, dividing up whatever loot is left over.
So on any given day, the "government" of the KSA can support terrorists and claim to be waging all-out war against them. Both cases are 100% true. One Prince gives millions to bloodthirsty Imams. Another Prince gives millions to a hospital. Arabs don't think they lie, the guy talking just tells you some of what he thinks you might need to know about what HE might be doing, at the moment.
In my dealings in the KSA, where I worked for a long while, my model was "Colombo," "Just one more question, Mam." And Eliot Ness. Checkers doesn't work when the worthy oriental gentlemen are playing high level chess! Also, once you realize that nothing is going to happen until ALL the relevant princes are happy, it's interesting.
