You probably didn't see it on cable news, but on Tuesday last week the 32-year-old Saudi Crown Prince Mohammed bin Salman gave a speech that could have profound consequences for the future of the Middle East and the fight against radical Islamic terrorism.

MBS, as he's often known, told a gathering of the world's wealthiest investors and powerful political figures in Riyadh that he will return his country to "moderate Islam." A source who was in the audience for the speech said people were shocked to hear this said in public by one of the leaders of the country that keeps the two holiest sites in Islam.
