The Cold War was not simply a duel of superpowers. It took place not just in Washington and Moscow but also in the social and political arenas of geographically far-flung countries emerging from colonial rule. Moreover, Cold War tensions were manifest not only in global political disputes but also in struggles over technology. Technological systems and expertise offered a powerful way to shape countries politically, economically, socially, and culturally. Entangled Geographiesexplores how Cold War politics, imperialism, and postcolonial nation building became entangled in technologies and considers the legacies of those entanglements for today's globalized world. The essays address such topics as the islands and atolls taken over for military and technological purposes by the supposedly non-imperial United States, apartheid-era South Africa's efforts to achieve international legitimacy as a nuclear nation, international technical assistance and Cold War politics, the Saudi irrigation system that spurred a Shi'i rebellion, and the momentary technopolitics of emergency as practiced by Medecins sans Frontières. The contributors to Entangled Geographies offer insights from the anthropology and history of development, from diplomatic history, and from science and technology studies. The book represents a unique synthesis of these three disciplines, providing new perspectives on the global Cold War.
