From the former secretary of defense, a strikingly candid, vividly written account of his experience serving Presidents George W. Bush and Barack Obama during the wars in Iraq and Afghanistan. Before Robert M. Gates received a call from the White House in 2006, he thought he’d left Washington politics behind: after working for six presidents in both the CIA and the National Security Council, he was happy in his role as president of Texas A&M University. But when he was asked to help a nation mired in two wars and to aid the troops doing the fighting, he answered what he felt was the call of duty. Now, in this unsparing memoir, meticulously fair in its assessments, he takes us behind the scenes of his nearly five years as a secretary at war: the battles with Congress, the two presidents he served, the military itself, and the vast Pentagon bureaucracy; his efforts to help Bush turn the tide in Iraq; his role as a guiding, and often dissenting, voice for Obama; the ardent devotion to and love for American soldiers—his “heroes”—he developed on the job. In relating his personal journey as secretary, Gates draws us into the innermost sanctums of government and military power during the height of the Iraq and Afghanistan wars, illuminating iconic figures, vital negotiations, and critical situations in revealing, intimate detail. Offering unvarnished appraisals of Dick Cheney, Joe Biden, Hillary Clinton, and Presidents Bush and Obama among other key players, Gates exposes the full spectrum of behind-closed-doors politicking within both the Bush and Obama administrations.
