In the years around the Second World War, policymakers in the United States and Western Europe faced unique security challenges occasioned by the development of new technologies and the emergence of transnational ideological conflict. In coming to terms with these challenges, they developed the historically novel practice in which a state might maintain a long-term, peacetime military presence on the territory of another sovereign state without the subjugation of the latter. Such basing arrangements between substantive equals were previously unthinkable: under the inherited understanding of sovereignty, in which there was a tight linkage between military presence and territorial authority, such military presences could only be understood in terms of occupation or annexation. These "sovereign basing" practices, as I call them, are now central to many aspects of contemporary security politics. This book applies concepts derived from pragmatist thought to a historical study of the relations between the United States and its wartime allies to explain the origin of this phenomenon. A pragmatist lens draws attention to how the actors involved creatively recombined inherited practices in response to changes in the material and social context of action and thereby transformed the practice of sovereignty. The tools offered by pragmatism provide needed analytical leverage over the emergence of novelty and offer valuable insight into the dynamics of stability and change. The practice of sovereign basing, bound up as it is now with the constitution of interests and understanding of how states exercise power, is likely a durable feature of international politics."--
