What if AlWaleed and some relatives wanted to stage a coup and remove King Salman and his son from power and push Saudi to moderate Islam, trump gives this American intelligence info to King Salman and his son and they arrested all the conspirators under the guise of corruption And now they parrot that same moderate BS just to make them look like the good guys? King Salman faciliated the largest Saudi purchase of American weaponry from Trump. To Trump Kind Salman and his son are great allies, he would do anything to keep them in power including tipping them off to plans hostile to them.
It was King Salman that started the bombing of Yemen , maybe AlWaleed and some others didn't like the direction the kingdom was headed in....
Also trump is a master of projection, accusing his enemies of exactly that which he himself is guilty of. Maybe King Salman and son are employing the same tactic
