Analysis: Al-Libi among last capable COOs (CBS News) Al Qaeda's number two -- Abu Yahya al-Libi -- had escaped from an American prison and dodged hellfire missiles aimed at him from U.S. drones. But al-Libi's luck has just run out. The United States confirmed Tuesday that an American drone killed him Monday in northern Pakistan. Abu Yahya al-Libi was one of the last-remaining pillars at the core of al Qaeda, reports CBS News correspondent Bob Orr. He was often the public face of terror, appearing in dozens of videos urging new strikes against the U.S. and its allies. But the charismatic terrorist was more than a propagandist. Al-Libi sat on al Qaeda's governing council, and as the top deputy to new al Qaeda chief Ayman al Zawahiri, al-Libi, oversaw external operations. U.S. officials say al-Libi was at the center of planning new attacks and coordinating al Qaeda's outreach to top affiliates like al Qaeda in Yemen. CBS News correspondent John Miller reports the killing means al Qaeda also lose, in effect, their Chief Operating Officer, the guy who went through the day-to-day job of running the complex organization. By having people like that, that's what allowed bin laden to hide as long as he did -- years longer than he would have if he were involved in the day-to-day business -- and it's also given the insulation to Ayman al-Zawahiri. U.S. strike kills al Qaeda's deputy leader Watch: Authors discuss Obama's reliance on drone warfare Is President Obama changing face of foreign policy? They also lose one of their last voices. Al Libi made 39 videos and was viewed within the organization as a legitimate scholar, and sat on the religious council as well as al Qaeda's board of directors. We have heard many times that the latest "number 2" in al Qaeda has been killed, but this may be the last commander within the organization with this level of management capability. Zawahiri has two choices now and both of them are bad. He can reach lower into an organization who's most capable people have been taken out in drone strikes and pick someone who is willing, or he can assume more of the job himself. That exposes him to greater risk of meeting the same end.
