The theoretical framework of the book is extremely thorough, with strong analytical components detailing both concepts and methods of accountability as derived from prior contributions. The initial assumptions of the research are entirely reasonable. The methodology of the substantive inquiry blends legal doctrinal scholarship with interviews with policymakers. This is a welcome addition to the previous literature on EU security and defence, which tended to focus on only one of these approaches ... Accountability in EU Security and Defence is an excellent product and an invaluable read for the specialist with an interest in the EU law or foreign affairs policy, and to those with an interest in the accountability of the EU more broadly.
