At Drudge Report the former head of the CIA’s Osama bin Laden unit, going public for the first time, says that bin Laden has obtained a fatwa from a Saudi sheikh authorizing him to use nuclear weapons against America. (Hat tip: Ethel C.)

Even if bin Laden had a nuclear weapon, he probably wouldn’t have used it for a lack of proper religious authority - authority he has now. “[Bin Laden] secured from a Saudi sheik…a rather long treatise on the possibility of using nuclear weapons against the Americans,” says Scheuer. “[The treatise] found that he was perfectly within his rights to use them. Muslims argue that the United States is responsible for millions of dead Muslims around the world, so reciprocity would mean you could kill millions of Americans,” Scheuer tells Kroft.

Scheuer says bin Laden was criticized by some Muslims for the 9/11 attack because he killed so many people without enough warning and before offering to help convert them to Islam. But now bin Laden has addressed the American people and given fair warning. “They’re intention is to end the war as soon as they can and to ratchet up the pain for the Americans until we get out of their region….If they acquire the weapon, they will use it, whether it’s chemical, biological or some sort of nuclear weapon,” says Scheuer.
