This book proposes that the United States Armed Forces consistently followed a strategy of attrition from the introduction of battalion sized combat troops in 1965, through the Westmoreland-Abrams transition, and ultimately encouraged the South Vietnamese to follow this strategy during the period of Vietnamization. General Abrams promoted a "one-war" strategy which had the desired end state of population security for the people of South Vietnam. In reality the "one-war" was a multi-tiered strategy of attrition. The training of South Vietnamese forces was predicated on their capability to conduct attrition warfare upon the departure of American forces. This book emphasizes the continuity of American strategy in the Republic of South Vietnam. Despite claims of a radical shift to counter-insurgency and pacification operations, General Abrams continued a consistent strategy he inherited from his predecessor; in turn he passed it on to the South Vietnamese. Any limited success achieved by the United States Armed Forces in South Vietnam was a result of attrition not counter-insurgency and that the ultimate failure was the inability to transition from attrition to maneuver.
