[Gould’s] shrewd analysis offers a valuable perspective on American history during a formative era… Scholars of European history have long argued for the primacy of foreign affairs in driving state formation and shaping politics. But American observers—scholars and generalists alike—have rarely applied this idea to the history of their own country before 1900. America in its formative stages is usually viewed apart from the international system—as a promised land separated from the rest of the world by two oceans and shaped by its own lofty ideals. But in fact, as Gould shows, America came into its own only by claiming full membership in the community of nations. Gould is right to give greater attention to this neglected theme in American history. -William Anthony Hay / Wall Street Journal
