David Halberstam's magisterial and thrilling The Best and the Brightest was the defining book about the Vietnam conflict. More than three decades later, Halberstam used his unrivaled research and formidable journalistic skills to shed light on another pivotal moment in our history: the Korean War. Halberstam considered The Coldest Winter his most accomplished work, the culmination of forty-five years of writing about America's postwar foreign policy.
