The Saudi royal family has survived the events of the Arab Spring intact and unscathed. Any major upheavals were ostensibly averted with the help of oil revenues, while the Kingdom's influential clerics conveniently declared all forms of protest to be against Islam. Saudi dollars bent eventsto the Kingdom's will in the Arab world - particularly in Syria, Yemen and Bahrain, but also in Egypt and Lebanon, Saudi cash has had a profound impact.Does this mean that all is well in Saudi Arabia itself, which has an extremely youthful population ruled by a gerontocracy?
