Contributor(s): Professor Etel Solingen | The 2020 Susan Strange lecture will pay tribute to Professor Strange's contributions by focusing on the international political economy dimensions of nuclear choices, for or against nuclear weapons. Whereas relative power and security dilemmas have dominated the study of nuclear proliferation for decades, an approach centered on the "cui bono" (who benefits) question reveals how domestic distributional implications related to the global economy have systematic effects on states’ nuclear choices. Etel Solingen is the Thomas T. and Elizabeth C. Tierney Chair in Peace and Conflict Studies at the University of California Irvine and the Susan Strange Visiting Professor, 2019-20 at LSE. She received the 2018 William and Katherine Estes Award from the National Academy of Sciences recognizing basic research on issues relating to nuclear weapons. She is a former President of the International Studies Association and the recipient of the 2019 Distinguished Scholar award in International Security. Karen E Smith is a Professor of International Relations and Head of the Department of International Relations at the London School of Economics and Political Science, and Director of the European Foreign Policy Unit (within the International Relations Department). The International Relations (IR) Department (@LSEIRDept) is one of the oldest as well as largest in the world. We are ranked 4th in the QS World University Ranking by Subject 2019 tables for Politics and International Studies.
