Two broad competing normative conceptions of war can be distinguished in the history of legal and political thought. The first and nowadays more familiar belongs to the tradition of \"just war.\" It sees war as an instrument of justice, indeed the most extreme form of supra-national lawenforcement, justified only in the most serious cases of violation of right. The second conception has been labelled \"lawful\", \"legitimate\", or \"regular war\", where war is not enforcement of justice, but a legally regulated procedure governing the pursuit of conflicting legitimate claims amongequal and autonomous political entities. This book sheds light on the relationship between law and morals in armed conflict, and can be read as a historical argument against the disappearance of the regular war concept. Kalmanovitz highlights three important contemporary challenges: the juridification of aggression and the \"turn to ethics\"in international law; the progressive individualization of war; and the predominance of asymmetrical warfare and armed nonstate actors. This study of the regular war tradition brings historical and theoretical perspective to these recent conceptual transformations, which undermine the fundamental and long-standing distinction between war and police action. It contributes to clarify the stakes in the erosion of internationalpluralism and the normative depoliticization of war. In revisiting the regular war tradition, a clearer sense of these ongoing transformations is realised, inspiring fresh perspectives on the justifiability of war. | The Laws of War in International Thought by Pablo Kalmanovitz, Hardcover | Indigo Chapters
