Ellsberg's transformation from cold warrior and Defense Department analyst to impassioned antiwar crusader who released the Pentagon Papers to the New York Times in June 1971 makes a remarkable and riveting story that still shocks 30 years later. Avoiding, for the most part, self-justification and self-aggrandizement, he clearly relates the experiences that led him to reject as arrogant lies the premises six presidents presented to the public and Congress to secure support for the Vietnam War. He describes the disjunction between what he saw during visits to Vietnam in the early and mid-'60s, driving through dangerous Viet Cong-held territory, and what was told to the press and public. And he recalls his first reading of the classified documents later known as the Pentagon Papers, which exposed the motives, in his view unprincipled, behind American involvement in Vietnam. Ellsberg creates page-turning human drama and suspense in both his descriptions of his early experience accompanying U.S. combat missions in Vietnam and his days spent underground evading an FBI manhunt after the Times's publication of the Papers. Another strength of this memoir is Ellsberg's vivid recollections of meetings with prominent policymakers, from Henry Kissinger to Senator William Fulbright, that re-create the deep tensions of the Vietnam era. Ellsberg raises serious ethical questions about how citizens, politicians, the press and officials act when confronted with government actions they consider immoral and perhaps illegal. Ellsberg's own answer is history.
