The rapidly changing global energy supply situation, coupled with a host of social, political, and economic challenges facing consumer states, has significant implications for the United States generally and for the U.S. military specifically. The U.S. Army War College gathered experts from the policymaking community, academia, think tanks, the private sector, and the military services at the Reserve Officers Association in Washington, DC on 19-20 November 2013 to address first the major ‘new realities’ both geographically and technologically and then the specific military implications. This compendium of executive summaries is based on the presentations delivered at that conference, which was funded through the generous support of the U.S. Army War College Foundation.
