"A welcome and much needed contribution to thinking about international affairs in the wider liberal tradition, which is of interest to classical liberals and libertarians, but also appeals to IR scholars, philosophers, historians and the interested public." -Dr Edwin van de Haar - author of Human Nature and World Affairs: An Introduction to Classical Liberalism and International Relations Theory. Libertarian conversations about IR are few and far between. This volume shows how libertarians can contribute to a global IR conversation. - Kevin Doremus, Instructor of International Relations and Development at LCC International University A must-read, this collection captures the essence of the crossroads at which libertarianism finds itself today. A compelling invitation to partake in the urgent and challenging task of shaping the contours of alternative forms of sovereignty in a world of deep interconnectedness. -- Tiziana Stella, PhD, Executive Director of the Streit Council This volume initiates a welcome and overdue reorientation toward international affairs. With an international line-up of scholars, the chapters are fresh, provocative, and thoughtful and will stimulate debate on internationalist liberalism. --- Eric Schliesser, Professor, Political Theory, Department of Political Science, University of Amsterdam This book takes a hard look at libertarian foreign policy doctrines, especially those of non-intervention, interstate federalism, and non-aggression, and applies new insights to these old doctrines. Classical liberal thinkers such as Vincent Ostrom, James Madison, and F.A. Hayek have all hinted at the idea of world governance from a libertarian standpoint. Yet today, “the libertarian position” on foreign policy is either non-intervention from the US side of the Atlantic or half-hearted confederation from the European side of the Atlantic. This volume (I) hones in on the problems of Westphalian sovereignty and its nationalist shortcomings, while the other celebrates Westphalian sovereignty’s achievements in regards to keeping imperialism at bay.
