The Saudi’s may not have been direct co-conspirators, but a fair number of well placed individuals in their government/royal family facilitated the activities of Atta and the rest.

“The C.I.A. has no evidence that Director John Brennan is a muslim convert”
Bulletin:
CIA director and practicing Muslim John Brennan, longtime member of a governmental agency founded on deception, and more recent convert to a totalitarian ideology steeped in deception, assured all Americans that he, with his fellow Muslims in the House of Saud, are being completely transparent about their being completely innocent of any complicity in the 11 September 2001 act of war perpetrated on American soil by predominantly - 15 of 19 - citizens of Saudi Arabia.
Members of the press thanked him for his candor.
