This unique two-volume book covers virtually the whole spectrum of international conflict and security law. It proceeds from values protected by international law (Part I), through substantive rules in which these values are embodied (Part II), to international and domestic institutions that enforce the law (Part III). It subsequently deals with current challenges in the application of rules of international conflict and security law (Part IV), and crimes as the most serious violations of those rules (Part V). Finally, in the section on case studies (Part VI), lessons learnt from a number of conflict situations are discussed. Written by an international team of experts representing all the major legal systems of the world, the book is intended as a reference work for students and researchers, domestic and international judges, as well as for legal advisers to governments and international and non-governmental organisations.
