International Theory

International Theory is an interdisciplinary peer-reviewed academic journal published triannually by Cambridge University Press, with the support of the David L.

The current editors are Claudia Aradau (King's College London), Catherine Lu (McGill University), and David A. Welch (Balsillie School of International Affairs, University of Waterloo); the Associate Editor is Mark Raymond (University of Oklahoma).
