"Sauer ... shed new light on a phenomenon (and on a country case) that has been explored already in detail and from different perspectives ... . Regarding research design, Sauer skilfully navigates between utilizing, criticizing and enriching the state of the art, and between methodological reflexivity and pragmatism. Regarding theory building, his micro-level focus on individuals, as well as on emotions and fear in particular, opens up new perspectives for research on international norms and for International Relations in general."
