'The book is an excellent example of the 'positivist-objectivist' approach to interpreting the international law on the use of force. The result is a comprehensive and even-handed treatment of the many complex arguments on the urgent issue of our time, the legality of resort to military force.' Mary Ellen O'Connell, University of Notre Dame, Indiana
'As Professor of International Law at the University of Sussex and co-editor-in-chief of the Journal on the Use of Force and International Law, Christian Henderson comes from a position of exceptional expertise to explore the framework for the use of force by states. On the one hand, a state is forbidden from utilizing force against foreign states in an aggressive manner; but on the other, a sovereign entity is entitled to defend itself. Overarching this is the moral obligation to protect civilians and jus cogens norms. In light of this complexity, Henderson's practical exploration of the international law governing the resort to force provides an enlightening and practical perspective on the topic Overall, I would recommend this book.' Kathryn Allinson, Leiden Journal of International Law
'Henderson's book presents the competing views on many of these issues in a thoughtful, balanced, and scholarly manner, which makes the book highly suitable for use in teaching an advanced level course. As a whole, this is a deeply researched, comprehensive, and erudite contribution to the literature on the law governing recourse to force.' Allen S. Weiner, The American Society of International Law
'Henderson's book offers a comprehensive, pragmatic, thoroughly argued, and helpful access to the world of the ius contra bellum, precisely identifying and squarely addressing undeniable problems that rules governing the use of force face It will thus equip international lawyers at any level to critically engage with the use of force in international relations, to take upon future challenges and rene the law from a solid basis, and to defend it against death threats.' Benjamin K. Nussberger, Journal of Conict & Security Law
'The Use of Force and International Law is a book that oers signicant coverage of the topic without falling into the trap of being overly dense, meeting its primary goal of acting as an introduction for those who are new to the subject while also providing analysis at a level that will inform the work of established ad bellum scholars. It soon will be appearing on the reading lists for my students.' James A. Green, International and Comparative Law Quarterly
