The taliban revival : violence and extremism on the Pakistan-Afghanistan frontier
(Book)

"In autumn 2001, U.S. and NATO troops were deployed to Afghanistan to unseat the Taliban rulers, repressive Islamic fundamentalists who had lent active support to Osama bin Laden's Al-Qaeda jihadists. The NATO forces defeated and dismantled the Taliban government, scattering its remnants across the country. But despite a more than decade-long attempt to eradicate them, the Taliban endured--regrouping and reestablishing themselves as a significant insurgent movement. Gradually they have regained control of large portions of Afghanistan even as U.S. troops are preparing to depart from the region.
