Around the summer of 2006, the CIA sends up to 50 additional case officers to Pakistan and Afghanistan as part of a renewed effort to find al-Qaeda’s top leaders. This is said to be a dramatic increase in the number of CIA case officers permanently stationed in those countries. All of the newly arrived personnel are given the primary task of finding Osama bin Laden and his second in command Ayman al-Zawahiri. Some former CIA officials will say this new push comes after the White House pushed the CIA to step up the effort to find bin Laden. Mid-term US Congressional elections are being held in November 2006. However, the CIA will deny any pressure from the White House and say it was “driven solely by operational considerations.” But the renewed effort results in no significant leads on the whereabouts of bin Laden or al-Zawahiri. US intelligence officials will largely blame this on the peace treaty signed between the Pakistani government and Islamist militants in North Waziristan in early September 2006 (see September 5, 2006). As part of the treaty, the Pakistani army withdraws ten of thousands of troops from Waziristan and other tribal border regions where the hunt for al-Qaeda leaders has been focused. A senior US intelligence official will later comment: “Everything was undermined by the so-called peace agreement in North Waziristan. Of all the things that work against us in the global war on terror, that’s the most damaging development. The one thing al-Qaeda needs to plan an attack is a relatively safe place to operate.” The Los Angeles Times will comment, “The pullback took significant pressure off al-Qaeda leaders and the tribal groups protecting them.” [Los Angeles Times, 5/20/2007]
