Saudi Arabia’s longtime powerful ambassador to Washington, Prince Bandar bin Sultan, has been stripped of all his security and intelligence duties within days of Prince Salman taking over as the kingdom’s new ruler. Bandar had been locked in a bitter struggle with Interior Minister Prince Mohammed bin Nayef for the past two years over which of them was in charge of Saudi policy toward Syria and specifically whether to support rebel  Islamic militants there, a Bandar strategy Mohammed had strongly opposed. Now Mohammed has emerged in charge of both domestic and much of Saudi foreign security to the great relief of the Obama administration.
