The Saudis always play a complex game. They are allowing anti ISIL bases on their territory while funding extremist madrases in northern Pakistan in order to buy off their clergy at home. They maintain an ultra conservative religion in their capitol but many princes are known to party in the desert or in Europe. Their wealthy are Western educated but find it expedient to never question Islam as Christians question Christianity. These are Muslim not out of deeply held belief but because they have everything to lose by even examining other religions or atheism. Their real gods are, and always have been: oil, the dollar, and never changing anything which might upset their good life. They will allow anti ISIL training camps because they need the West, but should fundamentalist Islam succeed in forming a caliphate that might please many of their religious leaders, the princes would, as always, survive by cutting a deal.
