It seems the Saudis are doing a fine job of poisoning the relationship on their own.
After all, some 16 of the 19 hijackers on 9-11 were from Saudi Arabia. The Saudi government is providing financial support to Islamic extremist organizations, too. Sorry, but Saudi Arabia (described by some as the world's largest open air prison) has some pretty bloody hands. The big change is that we're calling them on it.
