Book excerpt: In this shocking exposé on the betrayal of South Vietnam, premier historian Larry Berman uses never-before-seen North Vietnamese documents to create a sweeping indictment against President Nixon and Henry Kissinger. On April 30, 1975, when U.S. helicopters pulled the last soldiers out of Saigon, the question lingered: Had American and Vietnamese lives been lost in vain? When the city fell shortly thereafter, the answer was clearly yes. The Agreement on Ending the War and Restoring Peace in Vietnam—signed by Henry Kissinger in 1973, and hailed as "peace with honor" by President Nixon—was a travesty. In No Peace, No Honor, Larry Berman reveals the long-hidden truth in secret documents concerning U.S. negotiations that Kissinger had sealed—negotiations that led to his sharing the Nobel Peace Prize. Based on newly declassified information and a complete North Vietnamese transcription of the talks, Berman offers the real story for the first time, proving that there is only one word for Nixon and Kissinger's actions toward the United States' former ally, and the tens of thousands of soldiers who fought and died: betrayal.
