Nuclear Al-Qaeda?

Mowatt-Larssen has been gathering this evidence since a few weeks after Sept. 11, when then-CIA Director George Tenet asked him to create a new branch on weapons of mass destruction in the agency's counterterrorism center. He helped Tenet prepare the chapter on al-Qaeda's nuclear efforts that appears in Tenet's memoir, " At the Center of the Storm." Now that the uproar over Tenet's mistaken "slam dunk" assessment of the Iraqi threat has died down, it's worth rereading this account. It provides a chilling, public record of al-Qaeda's nuclear ambitions.

Mowatt-Larssen argues that for nearly a decade before Sept. 11, al-Qaeda was seeking to acquire weapons of mass destruction. As early as 1993, Osama bin Laden offered $1.5 million to buy uranium for a nuclear device, according to testimony presented in federal court in February 2001. When the al-Qaeda leader was asked in 1998 if he had nuclear or chemical weapons, he responded: "Acquiring weapons for the defense of Muslims is a religious duty. If I have indeed acquired these weapons, then I thank God for enabling me to do so."

Even as al-Qaeda was preparing to fly its airplane bombs into buildings, the group was also trying to acquire nuclear and biological capabilities. In August 2001, bin Laden and his deputy, Ayman al-Zawahiri, met around a campfire with Pakistani scientists from a group called Umma Tameer-E-Nau to discuss how al-Qaeda could build a nuclear device. Al-Qaeda also had an aggressive anthrax program that was discovered in December 2001 after bin Laden was driven from his haven in Afghanistan.
