These are the people who attacked America on 9/11. They agreed to help Bush in his war so we didn't attack them.

If I were a conspiracy theorist, I would say that the US worked with them closely before 9/11 and then enacted pre-written legislation immediately after the attack that our intelligence agencies knew was coming. Everybody in the middle was doing their job but our senior representatives never acted on the intelligence that was available. So now Saudi gets special treatment.
