Summary and Keywords
The concepts of ethics, justice, and security are inextricably linked within the field of International Relations (IR). In IR, three concepts are most often deployed in understanding the ethics of security: norms, rules, and laws. These norms, rules, and laws evaluate security, which is an alternative concept for describing what IR as a discipline has long sought to address: namely, war. Hence, norms, rules, and laws provide a means to evaluate violence and war. Using the first three concepts to evaluate the latter two is the heart of ethics and security. The concept of justice, however, suggests that simple norms, rules, and laws may not be enough. There have been debates about the use of military force since ancient times—the Judeo-Christian, Greco-Roman, and Islamic traditions have their own conceptions of how war and violence ought to be addressed. One of the more prominent ideas drawn from these debates is the concept of the “just war,” which emerged from Christian tradition. The concept of just war has played a role in constructing the international legal tradition. This tradition as an explicit moral one was subsumed into international law during the nineteenth century, but re-emerged in the mid-twentieth century. Today, it has become an influential source of critical reflection upon both legal and practical dilemmas in international security, informing a wide range of debates around the world.
