Lehmann has won Hamilton College’s most distinguished teaching awards, including most recently in May 2013, the Sidney Wertimer Award by the student assembly. Lehmann published “Keeping Friends Close and Enemies Closer: Classical Realist Statecraft and Economic Exchange in U.S. Interwar Strategy,” in Security Studies in 2009. His forthcoming article “It Takes a Quaker to Destroy the Global Village: Herbert Hoover, the Manchurian Incident and the League of Nations,” reverses common understandings of U.S. isolationism and Anglo-American relations and explains the demise of democratic internationalism by focusing on Herbert Hoover’s deeply flawed statecraft. Lehmann has written three pieces on the Iraq War and American hegemony as well as a book chapter on contemporary Sino-American rivalry. His first book manuscript explains the origins of American hegemony and details the centrality of the Pacific theater to the global war that still defines international order. Its title is Slippery Perch: Oil and the Asian Origins of American Hegemony. Lehmann is also editing a volume of global energy experts for Lynne Rienner press, Scarcity or Plenty? The International Political Economy of Global Natural Resources that will be published in 2014. Lehmann teaches “International Political Economy,” “The International Politics of Oil,” and “U.S. Foreign Policy,” among other introductory and seminar courses.
