The tribal region bordering Afghanistan, known as FATA (Federally Administered Tribal Area), has always been only loosely under government control. But since 2001 it has become a hornet's nest of violent extremists, many of whom have turned against their own state. In this groundbreaking book based on accounts by high-level Pakistani intelligence and military operatives and extensive firsthand reporting in villages where no American would be safe, award-winning reporter and broadcaster Imtiaz Gul chronicles his country's alarming slide into militancy. The United States is mired at great expense in Afghanistan, but Pakistan poses a far greater threat to American interests and to global security.
