Just War Theory

“For war, as a grave act of killing, needs to be justified.” These words were written by Murray N. Rothbard, dean of the Austrian School and founder of modern libertarianism, who spent much of his academic career trying to determine what, exactly, defined a “just war”. In fact, for as long as humans have been fighting wars, there have been quotations referring to the justification and moralities of wars and how warfare can be considered fair and acceptable to each society’s individual standards. While the time and place of each war differs, the reality of the devastation of battle may be found warranted by those fighting using these just war standards to vindicate their actions.

According to James Pattison, just war theory covers many conditions and splits itself into two categories: one of them is jus ad bellum, which

Another principle of just war is reasonable chance of success, these principle advices nations not to resort to war when they see the results will be futile. For example if a small nation is attacked by a greater nation, it should not opt to go to war since it has no chance of success. Such a nation needs to do nothing and hope to make use of diplomatic resolution in the future.

The legitimate defense of a nation and the responsibility of the Security Council to take actions in the course of maintaining peace within its areas of influence. With the establishment of United Nations and the modernization of war and its materials; the theories and doctrines of the past also needed to evolve. The modern Just war theory in composed of two principles: jus ad bellum, the right to conduct war, and jus in bello, the correct conduct within war. Each principle also has its own set of criteria to follow. Jus ad bellum contains six: Just cause, right intention, proper authority and public declaration, last resort, probability of success, and proportionality. (Orend, 2006)

According to Hedley Bull, war is “organized violence waged by sovereign states” which was the outcome of a “process of limitation or confinement of violence” via the ethical doctrine of just war theory. Clausewitz classified warfare as not just an act, but also a social institution for obtaining ulterior objectives (e.g. political) and strategic lines of command within and between states. He defined the social relationship between forces and the elements of war (rationality, chance and violence). Martin Shaw claims that contemporary warfare has completely evolved so that the “core of the new mode of warfare is a different general relationship between war fighting and the political, economic, and cultural-ideological domains.” (Nowaczynski, J. (2012, December). E-International Can

St. Augustine provided comments on morality of war from the Christian point of view (railing against the love of violence that war can engender) as did several critics in the intellectual flourishing from the 9th to 12th centuries. Just war theorists remind warriors and politicians alike that the principles of justice following war should be universalizable and morally ordered and that winning should not provide a license for imposing unduly harsh or punitive measures or that state or commercial interests should not dictate the form of new peace. “The attraction for jus post bellum thinkers is to return to the initial justice of the war”. This means that war is considered as self-defense.

The question "Can war be justified?" plagued mankind since the first war. The Just War Theory holds that war can be just. The theory has evolved for thousands of years and modern theorists, such as Michael Walzer, author of Just and Unjust Wars, puts forth criteria for a just war, such as jus ad bellum and jus in bello. Jus ad bellum includes reasons for going to war, and jus in bello deals with the people who wage war. The criteria in jus ad bellum include; just cause, declaration by a proper authority, right intention, a reasonable chance of success, the end proportional to the means, and war as a last resort. Jus in bello includes keeping innocents outside the field of war, and limiting the amount of force used. Just War Theorists

According to traditional just war theory, a just cause must serve peace and not simply protect an unjust status quo. War must be used as a last resort and all pacifistic approaches must be

The theory is not intended to justify wars but to prevent them, by showing that going to war except in certain limited circumstances is wrong, and thus motivate states to find other ways of resolving conflicts. A war is only a Just War if it is both justified, and carried out in the right way. The circumstances of Just-War Theory must be of: Last Resort, Legitimate Authority, Just Cause, Probability of Success, Right Intention, Proportionality, and Civilian Casualties.

“War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other’s children. This famous quote is from James Earl “Jimmy” Carter, Jr., who served as the 39th President of the United States. It implies that war can be justified under strict circumstances where it can be necessary, but it is still abhorrent. War is defined as a state of armed conflict between different countries or different groups within a country. Justification refers to the action of showing something to be right or reasonable. War brings many negative and catastrophic impacts not just to the country, but to the people living in the country as well, which this paper

The Just War Theory is a doctrine founded by Saint Augustine which has helped bring much discussion and debate to wars and the morality to fight in them. Wars and fights between people have gone on forever and are not perceived to stop anytime soon so it is important that some people thought about when and why they should ever fight. For many years Christians never part toke in this fighting due to teachings of the Bible and Jesus' teaching on 'turning the other cheek' and 'live by the sword, die by the sword'. Saint Augustine would be one of the first to talk about how a Christian could be a soldier and serve God at the same time. Through this thought we would receive the Just War Theory which gave a set of requirements for someone to partake

Classical realist theory is based upon the idea that human nature is inherently bad and selfish, the international system is anarchic, and the state is the most important actor in international affairs. Basing policy decisions on human nature, the state looks to maximize it’s power and security within its geographic location. Realist theory sees all conflict deriving from power struggles between states, though it is not about fostering wars; rather the opposite.

There must be a just cause when resorting to war. This can imply either self-defence actions or be fought in order to provide humanitarian aid to the victims of aggression.

Jus in Bello falls between two broad categories of discrimination and proportionality. Discrimination and proportionality are key factors that must be considered when engaging in war. For example, Michael Walzer argues, “war should only occur between combatants – soldier to soldier and noncombatants should be shielded from harm”. 2 Essentially, this means during times of conflict only legitimate targets should be targeted, combatants should distinguish against whom is attacked and should not include innocent bystanders. Furthermore, Alexander Moseley states, “In waging war, it is considered unfair and unjust to attack indiscriminately since non-combatants or innocents are deemed to stand outside the field of war”. 3 Unfortunately, this can be difficult at times since it may be hard to distinguish a combatant from a non-combatant especially since they do not always wear a uniform or carry arms, making it impossible to distinguish between them.

This essay intends to define and give an overview of the ‘Principles of War', the philosophers that coined these principles and with examples from the various countries that used and have their own perspectives on the ‘Principles of War'.
