Saudi Prince Turki al-Faisal, an influential member of the Saudi royal family and former head of its intelligence service, says the U.S. should kill Osama Bin Laden and then " get the hell out" of Afghanistan.

Turki, who was also Saudi ambassador to the United States from 2005 to April 2009, likened al Qaeda to a "cult"  and its leader to a  "hydra head with venomous snakes."

To destroy the cult, he said, "you have to cut off the head."

"After that," he advised, "declare victory...then get the hell out of  Afghanistan."
