CONSTRAINTS ON THE WAGING OF WAR This fully revised fourth edition of Constraints on the Waging of War considers the development of the principal rules of international humani- tarian law from their origins to the present day. Of particular focus are the rules governing weapons and the legal instruments through which respect for the law can be enforced. Combining theory and actual prac- tice, this book appeals to specialists as well as to students turning to the subject for the first time. frits kalshoven is Professor Emeritus of Public International Law and of International Humanitarian Law at the University of Leiden.
