"This is, as far as I am aware, the only book of its kind, devoting such focused, thorough and systematic treatment to the consideration of a specific conventional weapon, and its harmony with the principles of distinction and unnecessary suffering in international humanitarian law. This fact, and the quality of Barak’s analysis, makes this book a significant contribution to existing literature in international humanitarian law, both in its specific analysis with regard to flechette weapons, but even more importantly, in its exemplary demonstration of a template for application of these principles, which can and should be used by other scholars when considering the legality of other weapon technologies.Deadly Metal Rain is a masterful achievement, and an exemplary piece of legal scholarship; well organized and thorough in its scope, and demonstrating a deep understanding on the part of the author of the complexities and nuances of the relevant legal standards, and a rare ability to apply interdisciplinary analysis to holistically, creatively and persuasively apply these standards."Daniel H. Joyner, Journal of Conflict & Security Law,Volume 19 issue 3, Oxford University Press 2014.
