According to author Ron Suskind, some time in November the US makes a deal with Pakistani President Pervez Musharraf. Pakistan will seal off the passages to Pakistan from the Tora Bora region in Afghanistan where Taliban and al-Qaeda forces are expected to gather. In return, the US will give Pakistan nearly a billion dollars in new economic aid. Pakistan will fail to effectively seal the border in the next month (see December 10, 2001) and almost the entire force in Tora Bora will escape into Pakistan. [Suskind, 2006, pp. 58]
