Pakistani President Pervez Musharraf had promised to seal off the Pakistani side of the border near the Tora Bora region of Afghanistan in return for considerable US economic aid (see November 2001). But Musharraf spent two weeks negotiating with tribal chieftains on the border before starting the deployment. Around December 10, two brigades begin to take up positions along the border. [Christian Science Monitor, 3/4/2002; Newsweek, 8/11/2002] However, Pakistan does not seal several important parts of the border. The regions of North and South Waziristan, Dir, Chitral, and Balochistan have no Pakistani army presence whatsoever. Bin Laden and many other al-Qaeda leaders likely escape into Waziristan, where they begin to rebuild al-Qaeda (see December 2001-Spring 2002). The CIA intercepts communications between Pakistani officers warning not to harass any foreign fighters entering Waziristan. Several US officers will later tell Pakistani journalist Ahmed Rashid that they suspect Pakistan deliberately failed to guard these regions in order to allow the fighters to escape. [Rashid, 2008, pp. 148] On December 11, Defense Secretary Donald Rumsfeld says of this border region, “It’s a long border. It’s a very complicated area to try to seal, and there’s just simply no way you can put a perfect cork in the bottle.” [Christian Science Monitor, 3/4/2002] But armed gunmen storm the Indian Parliament on December 13, and a group based in Pakistan and allied with al-Qaeda is blamed (see December 13, 2001). Tensions suddenly rise between India and Pakistan, and Musharraf halts troop deployments to the Afghan border. The border near Tora Bora still is not adequately guarded by Pakistan when the battle of Tora Bora ends on December 17. Less than 100 stragglers entering Pakistan around December 19 are captured by Pakistani forces, but a number of these subsequently escape. [Newsweek, 8/11/2002]
