Though much has been written about the machinations of the Bush Administration and the recent failures of the Central Intelligence Agency, there is still a great deal of information that remains unknown to the American public. In this eye-opening new book, former CIA division chief Tyler Drumheller explores the gradual erosion of the agency's independence over the past 30 years, witnessing its decline through the prism of his own experiences. A dedicated intelligence professional, Drumheller worked for several administrations, from Ronald Reagan to George W. Bush, rising through the ranks to become head of the agency's European division. From that privileged position he watched with growing dismay as the CIA descended into bureaucratic inertia and later, with anger as ideological powerbrokers used the agency to achieve their own political goals. At Langley, Drumheller had a front row seat alongside Dick Cheney, Condoleeza Rice, Colin Powell, and George Tenet. As only a few insiders can, he offers first-hand insight into the agency's relationship with the Bush Administration, sheds new light on how America propelled itself into war with Iraq, and explains how it has had a detrimental effect on our abilities to defend ourselves. Sure to join the ranks of such groundbreaking bestsellers as Against all Enemies, Imperial Hubris, See No Evil, and Plan of Attack, On the Brink is an important contribution to contemporary American history, and a riveting must-read for concerned citizens on both sides of the political divide.
