From just several hundred advisors at the start of the decade, to more than 550,000 American troops by the end of it, the escalation of the war in Vietnam – and the fighting and the dying – brought social and political polarization back home. It was also televised – and, the more Americans saw of the war, the more unpopular the conflict became. Tim O’Brien, Frederik Logeval, Karl Marlantes, Neil Sheehan, Andrew Bacevich, George Herring, Tom Hayden, and Philip Caputo discuss the Gulf of Tonkin, and LBJ, for this most complex of American stories.
