The primary worship of the House of Saud is money and power and not Islam. With al-Qaeda and OBL and the terrorist associated Sadaaaam Baaaathist party removed, the House of Saud will most likely be very happy selling the world oil and controlling and modifying its jihadists. That is most likely what was talked about several years ago in Crawford and that is most likely what is being watched for by the current administration.
Any princes who left the reservation, who are found to have funneled money directly to OBL or other terrorist groups should be dealt with when the time comes on an individual basis.
There will be no overworked U.S. armies marching into S.A. and there will be no glass parking lot explosion fields in Mecca.
