This chapter examines the main theoretical approaches to war and the circumstances under which it is permissible to wage war. War is one of the most morally difficult, and morally pressing, aspects of human existence. It nearly always involves killing and maiming on a vast scale. Despite its destructive nature, and despite the rise of rights talk on the international stage and the spread of democracy across large parts of the world, war persists. The chapter first considers the just war tradition and alternatives to just war theory before discussing two theoretical approaches to the ethics of war: collectivism and individualism. It also explores three principles that govern the fighting of war: jus ad bellum, jus in bello, and jus post bellum. A case study on Afghanistan and the ‘war on terror’ is presented, along with Key Thinkers boxes featuring Michael Walzer and Jeff McMahan.
