In this critical examination, Dan Yahav delves into the complex concept of 'Purity of Arms' (Tohar HaNeshek), a foundational ethical principle of the Israeli Defense Forces. The book meticulously dissects the mythology surrounding the IDF's moral conduct, contrasting it with the stark realities of military occupation and conflict. Through historical analysis, soldier testimonies, and case studies, Yahav exposes the significant gap between the proclaimed ideal of using force only when necessary and the actual practices on the ground. It is a thought-provoking analysis of military ethics, national identity, and the moral compromises inherent in prolonged conflict.
