Every few months, America’s four-star admirals and generals gather at a military base not far from Washington to participate in what General Martin E. Dempsey, Joint Chiefs of Staff chairman, calls his ‘strategic seminar’. The aim is to foresee the future, anticipating security challenges that the United States will face in the coming years, thereby enabling the Pentagon to prepare itself accordingly. With that end in mind, Dempsey and his colleagues engage in what the New York Times has styled ‘a lethally earnest game of Risk’, participants striding across ‘a giant map of the world, larger than a basketball court’ as they posit various crises and speculate on the response each might entail.
