I don't know details of nuclear deal, but any such deal with Saudi Arabia would seem bad (like past deals with N.Korea and Iran). I assume you agree? Or are you just being partisan?
The fact that the 9/11 planes were filled with al Qaeda recruits from Saudi Arabia is problematic. The worst 2 out of the 3 main flavors of Islam are in Saudi Arabia and Iran. Seems like things would be far, far worse for the US if the royal family lost their grip on things in Saudi Arabia. Do you agree?
