Applying role theory and Putnam's two-level game framework to the European migration crisis of 2015, Magdalena Kozub-Karkut expertly shows how the Czech Republic, Slovakia, Hungary, and Poland used the crisis to contest their roles in the European Union (EU) and how each country and the V4 as a group, subsequently used their new contested roles in the bargaining process within the EU structures.  In doing so, Kozub-Karkut demonstrates how international negotiations might be used by the chief negotiators as a way of triggering contestation and enhancing their position at the domestic level as well as how role contestation processes from the domestic level might be used at the international one.
Two-Level Role Theory and EU Migration is an excellent resource for scholars and students of Foreign Policy Analysis, International Relations Theory, European Studies, and Migrations Studies.
