In this fascinating history of Cold War cartography, Timothy Barney considers maps as central to the articulation of ideological tensions between American national interests and international aspirations. Barney argues that the borders, scales, projections, and other conventions of maps prescribed and constrained the means by which foreign policy elites, popular audiences, and social activists navigated conflicts between North and South, East and West. Maps also influenced how identities were formed in a world both shrunk by advancing technologies and marked by expanding and shifting geopolitical alliances and fissures. Pointing to the necessity of how politics and values were “spatialized” in recent U.S. history, Barney argues that Cold War–era maps themselves had rhetorical lives that began with their conception and production and played out in their circulation within foreign policy circles and popular media. Reflecting on the ramifications of spatial power during the period, Mapping the Cold War ultimately demonstrates that even in the twenty-first century, American visions of the world — and the maps that account for them — are inescapably rooted in the anxieties of that earlier era.
