IR theory and international history
Ethics of War
US Climate Change
His research combines IR theory and international history. After working initially on Soviet foreign policy, his research concentrated for many years on the history of nuclear strategy, especially Anglo-American relations. This developed into an associated interest in the ethics of war. He then produced a number of historical and theoretical works about globalization. During most of the past decade, he has been researching aspects of international legitimacy, and making the case for the importance of this hitherto neglected aspect of international affairs. Currently, he is investigating the forms, understandings, and distribution of vulnerability in international order.
