Why did Kennedy and his colleagues choose this perilous course in the midst of an uncertain civil war? To answer this question, The Year of the Hare takes us inside the Kennedy administration, where the State Department largely supported the coup while the Pentagon and the CIA consistently resisted it. Francis X. Winters's research is based on in-depth interviews with high-ranking members of the Kennedy administration, including Dean Rusk, McGeorge Bundy, and George Ball, along with the newly issued multivolume compilation Foreign Relations and the United States, 1961-1964, Vietnam and the recently opened General Records of the U.S. State Department for 1963.

The reasons for American support of the coup in Vietnam, Winters asserts, lie both in the ethos of the era, with its dynamic confidence in the superiority of American ideals, and in Kennedy's political aspirations. The Year of the Hare explores the synergy between the idealism and personal ambition that were at the root of our troubled memories of the war that haunts us still.
