On this installment of ST, we offer a discussion of how oil, coal, and other energy sources are influencing today's international geo-politics. Our guest is James Clad, a diversely experienced foreign-affairs and oil-policy expert who consults for various energy and investment firms worldwide. Clad is a senior adviser at the Center for Naval Analyses (CNA) in Arlington, Virginia, as well as an advisor to IHS Jane's and Cambridge Energy Research Associates (CERA). From 2002 to 2010, Clad served as U.S. Deputy Assistant Secretary of Defense for Asia, Senior Counselor and Director for Middle Eastern Affairs at the Overseas Private Investment Corporation, and Senior Counselor at the Agency for International Development. He has also been a Professor of Asian Studies at Georgetown University, has written several books, was trained as a lawyer in New Zealand, and has written articles for the Far Eastern Economic Review. Clad was in town earlier this week to address the Tulsa Committee on Foreign Relations on "The World Politics of a Changing Energy Landscape," and he stopped by our studios while he was here.
