This chapter begins with a brief sketch of the events that unfolded during the Cuban missile crisis. It describes the Executive Committee of the National Security Council, or the ExComm, consisting of Kennedy's cabinet, their immediate subordinates, the director of the Central Intelligence Agency, the chairman of the Joint Chiefs of Staff, and a number of other top-level advisers. It then turns to Kennedy's secret recordings of many White House meetings and telephone conversations, which capture more than twenty hours of ExComm deliberations. Next, it sets out the book's purpose, namely is to undertake the first sustained analysis of the ExComm recordings. The goal is to mine the details of these discussions from a sociological perspective that views conversation as an achievement unto itself, and anything achieved through conversation as indelibly shaped by its rules, constraints, procedures, and vicissitudes.
