A busy day in Saudi Arabia. Not only the resignation of Saad Hariri. But Prince Mit`ib bin Abdullah has been removed from the National Guard. This is the first time that the National Guard is not in the hand of Abdullah or his son. That put all apparatus of the military-intelligence network in the hands of Muhammad bin Salman. News that Al-Walid bin Talal has been arrested and accused of money laundering. This could be a service to Trump, who hates Al-Walid: the two fought it out on twitter during the campaign although Al-Walid tried to reconcile with Trump after his election but to no avail.
