"The focus on three rather than on only one organization sets the book apart from other contributions…International Organizations and Military Affairs seems to answer the broader question of how the member states try to minimize agency costs (states can do this through non-delegation, agent selection, or actual control.) The book will be of interest to scholars working in the principal-agent tradition, but also to anyone working on international peacekeeping and international organizations more broadly." - Kseniya Oksamytna, University of Warwick, ACUNS"International Organizations and Military Affairs breaks new ground in that it thoroughly applies [principal-agent] insights to new territory and moreover does so in a comparative fashion – two significant lacunae in the study of security IOs. [It] provides a fruitful starting point for inquiring into P/A dynamics across a greater range of security IOs, deployment cases, and stages of the policy cycle … Dijkstra in many ways steers us in the right direction." — Sebastian Mayer, University of Bremen"The book is rich in both its theoretical and empirical dimensions, and offers an encompassing and highly compelling analysis with many fresh insights.” - Mai’a K. Davis Cross, Northeastern University"International organizations and military affairs is an interesting and important book. It does what few people have done before, notably look comparatively as well as in a theoretically informed way at how states cooperate in military affairs through international organizations." - Anand Menon, King’s College London, International Affairs "Hylke Dijkstra has written a highly interesting book that deserves to be widely read ... The book is well written and the conclusion is refreshing ... The bottom line is that every analyst of international cooperation will benefit from Dijkstra’s careful assessment of institutional trends in the UN, NATO, and the EU." - Sten Rynning, University of Southern Denmark"At a point in time when global governance is running into the quicksand of power politics, it is well worth revisiting the underlying mechanics of international organisations. Hylke Dijkstra’s book does precisely that with respect to their growing role in military affairs." - Alexander Mattelaer, Institute for European Studies, Brussels"At a point in time when global governance is running into the quicksand of power politics, it is well worth revisiting the underlying mechanics of international organisations. Hylke Dijkstra’s book does precisely that with respect to their growing role in military affairs. It investigates the question how the member states of the UN, NATO and the EU control the different international secretariats they have set up for supporting the conduct of multinational military operations. As such, the book presents a set of original findings that are the product of meticulous research... Hylke Dijkstra has delivered a scholarly tour de force." - Alexander Mattelaer (2016): International organisations and military affairs, Defence Studies"Hylke Dijkstra’s book is a good read for those involved in the law of international organizations." — Ramses Wessel, University of Twente"International Organizations and Military Affairs captures the breadth and depth of the interconnections between member states and international secretariats. Moreover, it offers not only an important scholarly contribution, but also fills a crucial gap for anyone who seeks to gain a better understanding of the politics within international organisations and international military collaborations." — Kai Chen, LSE Review of Books
