Book excerpt: "Catton treats the Diem government on its own terms rather than as an appendage of American policy. Focusing on the decade from Dien Bien Phu to Diem's assassination in 1963, he examines the Vietnamese leader's nation-building and reform efforts - particularly his Strategic Hamlet Program, which sought to separate guerrilla insurgents from the peasantry and build grassroots support for his regime. Catton's evaluation of the collapse of that program offers fresh insights into both Diem's limitations as a leader and the ideological and organizational weaknesses of his government, while his assessment of the evolution of Washington's relations with Saigon provides new insight into America's growing involvement in the Vietnamese civil war.".
