'A must-read for students of international relations theory, international security, and European studies, The Return of Geopolitics in Europe? by Stefano Guzzini and collaborators combines theory making, methodological innovation and comparative empirical analysis to deliver an outstanding and important book. This is not only because of the book's compelling answer to the puzzle of why a geopolitical school of thought began thriving in parts of Europe after the Cold War's peaceful end, but also as an exemplar of how excellent and rigorous constructivist theoretical and empirical research can and should be done.'
