The literature on grand strategy is dynamic and voluminous. Yet a vital set of questions remains unsettled. There is little agreement on such basic issues as a common definition of grand strategy, the appropriate methods that should be employed in studying it, which countries qualify as comparative cases, and whether the purpose of research is explanatory or prescriptive. This article examines four recent, important books as a platform for addressing these issues and argues that, as currently constituted, grand strategy is a field of study rather than a mature research program. It concludes by offering a modest range of options that can be employed to rectify these problems and develop a comparative grand strategy program
