Of course: Alwaleed bin Talal. Mohammed bin Salman arrested AbT, along with 16 others (#s I recall offhand), immediately after he became Crown Prince. They want their money, power, and lives back. Setting MbS up is the avenue. IMO, MbS got wind of the plan and had Kashoggi taken to save him. Meanwhile, we get this nonsense in the media, akin to Blasey-Ford, but even stupider, exposing EVERYONE involved.
They want their power back, and they're going to get fucked trying to get it. Trump told us he was on the verge of a solution. He just hasn't told us what that solution is.
