Winner of the 2018 National Book Critics Circle Award for NonfictionLonglisted for the 2018 National Book Award for NonfictionFrom the Pulitzer Prize-winning author of Ghost Wars, the epic and enthralling story of America's intelligence, military, and diplomatic efforts to defeat Al Qaeda and the Taliban in Afghanistan and Pakistan since 9/11Prior to 9/11, the United States had been carrying out small-scale covert operations in Afghanistan, ostensibly in cooperation, although often in direct opposition, with I.S.I., the Pakistani intelligence agency. While the US was trying to quell extremists, a highly secretive and compartmentalized wing of I.S.I., known as "Directorate S," was covertly training, arming, and seeking to legitimize the Taliban, in order to enlarge Pakistan's sphere of influence. After 9/11, when fifty-nine countries, led by the U. S., deployed troops or provided aid to Afghanistan in an effort to flush out the Taliban and Al Qaeda, the U.S. was set on an invisible slow-motion collision course with Pakistan.Today we know that the war in Afghanistan would falter badly because of military hubris at the highest levels of the Pentagon, the drain on resources and provocation in the Muslim world caused by the U.S.-led invasion of Iraq, and corruption. But more than anything, as Coll makes painfully clear, the war in Afghanistan was doomed because of the failure of the United States to apprehend the motivations and intentions of I.S.I.'s "Directorate S". This was a swirling and shadowy struggle of historic proportions, which endured over a decade and across both the Bush and Obama administrations, involving multiple secret intelligence agencies, a litany of incongruous strategies and tactics, and dozens of players, including some of the most prominent military and political figures. A sprawling American tragedy, the war was an open clash of arms but also a covert melee of ideas, secrets, and subterranean violence. Coll excavates this grand battle, which took place away from the gaze of the American public. With unsurpassed expertise, original research, and attention to detail, he brings to life a narrative at once vast and intricate, local and global, propulsive and painstaking. This is the definitive explanation of how America came to be so badly ensnared in an elaborate, factional, and seemingly interminable conflict in South Asia. Nothing less than a forensic examination of the personal and political forces that shape world history, Directorate S is a complete masterpiece of both investigative and narrative journalism.
