Historian Max Boot demonstrates how Edward Lansdale pioneered a “hearts and mind” diplomacy --- first in the Philippines, then in Vietnam. It was a visionary policy that, as Boot reveals, was ultimately crushed by America’s giant military bureaucracy, steered by elitist generals and blueblood diplomats who favored troop build-ups and napalm bombs over winning the trust of the people. Through dozens of interviews and access to never-before-seen documents --- including long-hidden love letters --- Boot recasts this cautionary American story, tracing the bold rise and the crashing fall of the roguish “T. E. Lawrence of Asia” from the battle of Dien Bien Phu to the humiliating American evacuation in 1975.
