Navies and Soft Power: Historical Case Studies of Naval Power and the Nonuse of Military Force, edited by Bruce A. Elleman and S. C. M. Paine, presents nine historical cases of the use of navies in nonmilitary missions. These studies, by established and emerging scholars in a wide variety of fields, support current U.S. Navy attempts to balance war fighting with an ever broader array of nonmilitary missions. They remind us that naval "soft power" concerns date from antiquity and that those facing the U.S. Navy have now become remarkably diverse.
