Saudi crown prince Mohammed bin Salman's aggressive power grab represents a huge gamble on the stability of his kingdom and its neighbors, but Donald Trump is not one to worry. The Washington foreign policy establishment may be agog at the young leader's "anti-corruption" purge of potential foes within the Saudi elite, but the US government barely flinched. No one is quite sure whether MBS' bold move will leave him as the uncontested leader of a more modern, open Saudi Arabia -- or open the door to chaos, rebellion or a regional war.
