This book investigates the legal status of depleted uranium weapons under international law. Jann K. Kleffner, an expert in international humanitarian law, examines the complex legal framework surrounding the use of depleted uranium (DU) munitions. The work analyzes the available scientific evidence regarding the environmental and health impacts of DU, juxtaposing these findings with existing international treaties and customary law. Kleffner's argument centers on whether the use of DU weapons violates principles of distinction, proportionality, and the prohibition of unnecessary suffering in armed conflict.

The book is recognized as a significant contribution to the legal scholarship on weapons of mass destruction and international humanitarian law. It is cited for its thoroughness in analyzing the scientific and legal dimensions of depleted uranium weapons. The work is considered essential for legal scholars, policymakers, and military strategists grappling with the ethical and legal challenges posed by modern armaments.
