The book presents a model of interaction effects between policymakers and the media which can shed light on the former's ability to enhance democratic legitimacy in foreign policy decision-making. Three types of interaction effects between the media and policymakers are identified within the European public sphere: indexing, bounding, and agenda setting. Empirically, two distinct areas of EU foreign policy are explored: the EU's approach to global climate change and its policy towards Russia. Nitoiu demonstrates in his central case study on the EU's approach to climate change the media's ability to endow EU foreign policy with democratic legitimacy, and how the EU has acted accordingly.
