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. The core themes revolve around the notion that emergent orders can be understood on a worldwide scale. 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, both of which are severely lacking in depth, sophistication, and creativity. The themes that emerg in this volume (I) are two-fold: one 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.
