Abstract

This dissertation aims to look at the moral justification for war in a critical way so that we can better understand both the justice and morality of war. In contrast to natural disasters, war has historically been viewed as an extreme manifestation of human social failure. The vast majority of theorists who address the morality of war do so within the moral framework established by Just War Theory; a normative account of war that dates all the way back to the Western Philosophical Tradition over 1500 years. Recent events in the conduct of wars around the world, however, have called into question the just war theory's relevance and applicability to contemporary wars. For instance, morality and virtue have had no place in society during recent wars. This work will examine several major theorists in the history of Western Just War Theory (St Thomas Aquinas and Augustine), demonstrating that the forefathers of Just War Theory did regard moral virtues and ethical principles as central to the morality of war. I will critically examine the concept of a just war through a discussion of various formulations of the realist and pacifist positions and argue that, while the just war tradition offers a reasonable alternative to either of these extremes, its glaring shortcomings (the theory's inability to address the rise of non-state actors such as al-Qaeda, the increasing availability of weapons of mass destruction, etc) should not be overlooked. Finally, I will argue that the theory of just war is obsolete, impractical, unrealistic, and flawed in the modern era, particularly if one wishes to maintain a moral constraint on war.
