Mohammed bin Nayef, 55, the new crown prince, is very much loved in the Beltway as a sort of top Saudi cop and a counterterrorism tough guy. He allegedly defeated al-Qaeda inside Saudi Arabia just for it to regroup in Yemen and now, for all practical purposes, enjoy indirect Mob help, adding new meaning to the concept of married to the Mob. His father, the ultra-right winger late Crown Prince Nayef, was colorfully known as the Black Prince.
