When I became secretary of defense, Ashton B. Carter said when announcing that the Pentagon would open all combat jobs to women, I made a commitment to building Americas force of the future. In the twenty-first century, that requires drawing strength from the broadest possible pool of talent.That pool of talentand how our nations civilian and military leaders have tried to fill itis what Military Service and American Democracy is all about. William Taylor chronicles and analyzes the long and ever-changing history of that often contentious and controversial effort, from the initiation of Americas first peacetime draft just before our entry into World War II up to present-day conflicts in Iraq and Afghanistan. A history that runs from the selective service era of 19401973 through the era of the All-Volunteer Force of 1973 to the present, his book details the many personnel policies that have shaped, controlled, and defined American military service over the last eight decades. Exploring the individual and group identities excluded from official personnel policy over time African Americans, women, and gays among others Taylor shows how military service has been an arena of contested citizenship, one in which American values have been tested, questioned, and ultimately redefined. Yet, we see how this process has resulted in greater inclusiveness and expanded opportunities in military service while encouraging and shaping similar changes in broader society.In the distinction between compulsory and voluntary military service, Taylor also examines the dichotomy between national security and individual libertytwo competing ideals that have existed in constant tension throughout the history of American democracy.
