David Rodin 
War and Self-Defense [PDF ebook] 

When is it right to go to war? The most persuasive answer to this question has always been ‘in self-defense’. In a penetrating new analysis, bringing together moral philosophy, political science, and law, David Rodin shows what’s wrong with this answer. He proposes a comprehensive new theory of the right of self-defense which resolves many of the perplexing questions that have dogged both jurists and moral philosophers. By applying the theory of self-defense tointernational relations, Rodin produces a far-reaching critique of the canonical Just War theory. The simple analogy between self-defense and national defense — between the individual and the state — needs to be fundamentally rethought, and with it many of the basic elements of international law and theethics of international relations.
