The 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 a halfhearted confederation from the European side of the Atlantic. The themes that emerge in this volume (II) are whether or not libertarian alternatives to the status quo are workable and, if so, whatwould they look like.
