Clay welcomes University of North Texas historian Geoffrey Wawro for a discussion of the War in Vietnam (1961–1975), which cost more than 58,000 American lives and hundreds of thousands of deaths in North and South Vietnam. Wawro, the author of seven books on the history of war, explains how a superpower got into a quagmire in a small Asian country. Why did Lyndon Johnson escalate the war between 1964 and 1968, when President John F. Kennedy made it clear that he would wind down America's involvement after he was re-elected in 1964? As the British essayist Christopher Hitchens insisted, is Henry Kissinger a war criminal? What was Richard Nixon's role in prolonging the agony? How should we assess Secretary of War Robert McNamara? Absent politics, could the war theoretically have been won by the United States and its reluctant allies?
