Iraq war (2003) A Brief History of The Just War Tradition (1 of 3)
Since Antiquity, the manifest and physical conflict between groups organised towards that end we call war, seems to be a fact of human nature or at least a fact of human society. The causes for war are numerous and of differing nature and vary, among others, according to time, place and culture. Many subjective and objective factors lead to wars. We can differentiate between those factors situated within the individual, the group or State or its international relations and those of various economical, political, militaristic and psychological developments.
Next to this casuistic approach, wars can be differentiated by ends, motives and justifications. The ends for which wars are waged are often not identical with its intentions or motives. Where the end might well be situated in the retrieval of lost goods or lost territory – sometimes a limited area of little political or economic use – the actual reasons might well be grounded in nationalism, as the indignity suffered by the nation convinces its subjects to restore the loss of face.
Nonetheless, justification of a war has always been a necessity. A necessity, because the principle exists in many cultures and religions that the killing and maiming of fellow humans is not self-evident, but that it requires justification. The use of physical force without any form of justification remains within the realm of the insane and madmen. In general, a person applies such force with reference to higher ideals, necessity or divine dispensation. It is, however, not only this ethical dimension that requires such justification. More pragmatic considerations sometimes require that we must first convince our allies of the justice of our cause before they are willing to participate in a war. This is especially true in democracies where such justification is also necessary to mobilise civilians for the war effort. Such legitimacy is most often in accordance with the opinion of specific communities.
However, the problem of such a term as legitimacy is that its meaning is not semantically fixed. In its philosophical approach the basis on which legitimacy or illegitimacy is assumed, refers to criteria that lie outside the judging subject . The characteristics of the legitimate political system are fixed within objective, philosophical definitions. This is different when we approach legitimacy from a sociological perspective. Here the criteria by which legitimacy or illegitimacy is assumed, exists in the minds of its judging subjects. This might imply that a political system, or at least a part or an aspect – e.g. war – of it, can be considered legitimate whereas it should be considered illegitimate by more objective standards of right and wrong. What is of paramount importance to the sociological approach is that a majority of the relevant community experiences the political system or an aspect of it as right. Nevertheless, in legitimising a justification for war, convincing the subjects of the political system often requires an appeal to the characteristics of objective legitimacy. However, this is not a requirement. It is important to note that these approaches exist next to each other. One does not exclude the other and I will make use of both of them.
The Just War tradition is the designation for a diverse collection of literature on the morality of war and its conduct, which academically is often referred to as respectively Ius ad Bellum and Ius in Bello. It aims at offering criteria by which a war is considered just and by which its conduct is considered just. The tradition as a whole does not argue against war but aims at restraining the resort to war and its conduct on a moral basis. In opposition to this, it should be noted that the Christian pacifistic movement, as part of this tradition, does argue against war. It is, however, not predominant.
The Just War tradition can be traced back to ancient Grecian philosophy when Plato and Aristotle offered their insights on war. During the Dark Age the sources for legitimising wars were the Old and New testament, the rules of law of the Romans, Greek philosophy and the Fathers of the Church of whom Saint Augustine of Hippo in the fifth century is most notable. In general, it is considered that Saint Thomas Aquinas in the 13th century was the first to approach the tradition systematically. Considering that saint Thomas Aquinas bases his work mostly on the thoughts of Augustine and Gratian, who in turn based their works on non-Christian Greek and Roman scholars, brevity on my part when considering these earlier scholars should be excused.
The Reformation in the 16th century did lead to a partial secularisation. During this time, most religious philosophers maintained that war for religion was the most just cause for the use of force. In opposition to this view stood those secular philosophers who thought about justice in war in terms of natural law.
As is apparent, the tradition is mostly Christian and Western, although a similar debate exists in Islam. Modernity also shows a greater participation by non-Western countries in the development of Just War thinking through international institutions such as the U.N. and the adoption of treaties. The prevalence of Western thinking is still obvious, which is most likely due to political, economic and social dominance of the West. The tradition’s universality can therefore be questioned but remains unchallenged, if for no other reason than the fact that the tradition has shaped the lines along which most western scholars think and they should not be disregarded by a simple act of will.
1. The Greeks & Romans
In the earliest times (750-500 BC) of Grecian history violence, plunder and sudden migrations were common in the area that is now the south and middle of Greece and the west coast of Asia Minor. Thucydides, an Athenian historian, notes that the lands that were called Hellas in his time (ca. 460-400 BC) had no permanent population in olden times. Migrations were common because the differing tribes easily left their territories under the pressures of superior forces of invaders. There was no trade between the different tribes, nor was there safe travel over land or by sea.
During Thucydides´ time things had changed to some degree. By this time stock-breeding became less important as opposed to agriculture. It was this stock-breeding that allowed for easy migrations before. As agriculture grew in importance, the leaders became aristocratic landowners who had their own retinue. They developed a system of values and rules, which they applied both in battle as well as in sports. Heralds and emissaries were spared, the dead of the enemy were returned for proper burial, they respected, if possible, the right of asylum of temples and other holy places and the substitution of wars of destruction by organised and regulated battles between champions or selected groups. The conquered population would not always be killed, but were often partially or entirely enslaved.
One of the first examples in which morality is seemingly separated from war is given in Thucydides’ History and is covered by Michael Walzer in Just and Unjust Wars as the “Melian Dialogue”. In this dialogue two Athenian generals meet with the magistrates of the island Melos. Melos was a Spartan colony and, although it rested on neutrality, refused to be subject unto the Athenians. The Athenian generals put forward that if they did not conquer what they could, they would reveal their weakness and invite attack and that it was therefore necessary to conquer what they could, which was in this case Melos. The Melian magistrates considered themselves innocent against men unjust and hoped for the assistance of Sparta. They thought of the Athenians unjust as they had no just cause to attack them. However, the Athenian generals pointed out that Sparta would do no such thing since they would only think of themselves as “they hold for honourable that which pleaseth and for just that which profiteth.”
It illustrates that one of the reasons, why the whole notion of morality in war would fail according to realists, is when those that resort to war are realists. That is to say, they consider war apart from normal life, where self-interest and necessity dictate their actions, and morality and law have no place. Nevertheless, as they consider war outside the realm of morality, they do so within the language of morality. Realists are still speaking on the subject of morality. They consider the conduct of war to be free of any moral constraints but justify this on the basis that winning a war is the highest good and that all other goods, for instance the rights of non-combatants and prisoners of war, are inferior to this goal. For war to be entirely free of morality it should be separated from the whole concept of winning and losing, as this concept in itself is normative. Yet, the object of war is to win by force that which cannot be obtained or is thought not to be obtainable by other means. So, as these realists first justify their need to wage war by pointing out that it is necessary, which in itself is a moral argument, they subsequently justify their conduct by referring to this necessity. And in all this they fail to answer vital questions; what is necessary? Is it necessary to kill civilians? And if so, when is it no longer necessary to kill civilians? Is it necessary to declare war on neutrals? Etc. Etc.
Leaving Thucydides and with him archaic Hellas behind, the Greece of Antiquity as it is generally known came into being with the development of the – incorrectly named – city-states (hereafter: "poleis"). Agriculture developed even further and gradually the poleis monopolised the use of force due to which the private wars of aristocrats and plunderers were considered illegitimate and therefore criminal. The poleis signed treaties with their neighbours in order to limit violence and this often led to a situation of peace (eirèné) between the contracting poleis. However, even after the development of the poleis, military expeditions would sometimes end up as expeditions of plunder under the direction of the general, in which neither friend nor foe was out of harm's way.
The philosopher Plato stated rules for the resort to war and the conduct of war in his Politea and Nomoi. He disapproved of expansive wars, civil wars and revolutions based on power politics or material ends and he felt that wars should only be waged as a last resort. The purpose of a war should be a new peace and the conduct should not be too harsh, especially against other Greeks, and the overbearing of women and mass slavery were wrong in his eyes. Plato also made a distinction between civil strife and war and the emerging idea of non-combatants can be inferred, at least in the case of civil strife, when he states that not the whole people of a poleis – its men, women and children – are to be regarded as enemies but only the hostile minority. Of course, this does allow for the hostile minority to be part of what we now consider non-combatants. Still, it is clear that he means to introduce some form of discrimination.
With respect to the conduct of war Aristotle agreed to a large extent with Plato and on the resort to war he said: "… for we are busy that we may have leisure, and make war that we may live in peace." That the object of war should be peace can be inferred from this. Despite this, the Greeks were thought to be superior to the barbarians, that is to say; those that were not Greek, and it was therefore their duty to subjugate and enslave them for the purpose of peace.
After the conquest of the Persian Empire (334-323) by Alexander the Great and his death, his empire fell apart in kingdoms, poleis and leagues of poleis. Between these a near constant state of conflict existed. Limited wars were fought by mercenaries, who had no interest in the annihilation of their "comrades in arms" because they might well lose the battle themselves on another day. Prisoners were released for ransom and truces were mostly upheld. In general the treatment of the conquered areas was more humane as an expression of the general humanisation of the relations between peoples from different communities.
The Roman Republic in the times of 600-300 BC shows little evidence of private wars. Perhaps this is due to the lack of sources on these times or perhaps it points to the possibility that the Roman Republic monopolised the use of force at an early age. According to Livius, a Roman historian of around 59-17 BC, the Romans had clearly defined ideas on the justification of wars from the beginning of their history and a complicated ritual for their declarations of war. As a reason for and a justification of wars the Romans identified the incursio hostilis, which is a breach of Roman territory, an attack aimed at an ally, infringement of treaty provisions, support to an enemy, not extraditing hostile persons and the molest of Roman emissaries. Nevertheless, these justification were often utilised as artificial excuses for aggressive wars. Even the expressed motivation for war was often a mere pretext, as the real reason was to acquire plunder, land and fame.
It was not until the era of Marcus Tullius Cicero (hereafter: "Cicero") that Roman thought on war and peace was established. During the times of Cicero the Roman Empire was inflicted with civil war that coincided with large military operations by Caius Julius Caesar and Cnaeus Pompeius. It was within these setting that reflections on the State, society, values for public and private life and the problem of war came into existence. Of the writers of these times Cicero is the most well known.
During the time of the Roman Empire the primary care for peace and justice rested with the government, including the emperor. This care referred to both the external peace, by protecting the border with a professional army, as well as the internal peace, by instituting courts and convicting criminals. The emperor alone was authorised and justified to use force.
According to Cicero a war was justified when negotiations with the enemy had failed, after which the enemy should be warned and finally war should be formally declared. He also considered that a new and better peace should be the aim of a war and that it should not be commenced without a valid reason. Peace to Cicero and other Romans of his time was the absence of hostilities. However, justice did not mean to Cicero what it means to us. A war for imperial glory was to him a legitimate motive for war, although he was of the opinion that such wars were to be fought with lesser intensity. As a matter of fact, justice to the Romans was mostly formalistic. Cicero did differentiate between civil wars and wars against others and separated defensive wars from aggressive wars, without condemning the latter.
In a just war the capture of civilians, the destruction of land and the plunder of cities was allowed according to Cicero. In practice, the warlords waged wars largely in the spirit of the times before Cicero. However, there was a tendency to give greater consideration to the justification of war. Caius Julius Caesar demonstrated his wars in Gaul as defensive wars and justified his ruthless treatment of certain Gaelic and Germanic tribes with rather forced reasoning in which he would depict his enemies as aggressors.
2. Early Christians & Augustine
The official position of the early Christians with regard to war was one of non-participation. In accordance with the Christian command "Thou shalt not kill", which was a command to the individual, the refused to serve in the Roman armies. It has also been put forward that Christians did not serve as soldiers, because it automatically required them to participate in idolatrous ceremonies. The early Christians were also expecting the return of Christ who would bring a new world. To them, peace was the Messiah's peace of God's kingdom to come and as such unattainable on earth.
This was the official line of the early Christian church until the beginning of the fourth century AD. The most influential change was the conversion of the Roman Empire to Christianity as its official religion within a century after the adoption of this religion by Constantine the great in 313 AD. Christian writers mainly copied the war ethics of Plato, Aristotle and Cicero.
According to these early Christian writers war should be a means in the hands of a sovereign instituted by God, which or who alone was allowed to take life. The war should be preceded by the proper diplomatic steps and should be waged as humanely as possible and should be waged with the right intention. A better peace should be its aim and unnecessary bloodshed should be avoided.
It was Saint Augustine that first established a firm Christian doctrine. When he did so he gave little consideration to wars of defence, because he thought such wars obviously justifiable and even obligatory. Augustine´s main exposition was on just wars of aggression. He required that the supreme authority alone was allowed to declare. Only an injustice or wrong caused by the enemy was considered as a sufficient justification for war, although the direct command of God could provide justification as well. It would seem that Augustine implies a right of punishment and he certainly accepts war as a means of God to punish the just as well as the unjust. He was, however, more concerned with defending and maintaining objective justice. Augustine insisted on war to be necessary and to have as its aim the achievement of peace, despite this he did not consider the contradiction and tension between war and peace. He thus leaves objective justice for what it is and from this the importance of the criteria of right intention might be inferred as it only leaves us with the subjective justice of these intentions.
As stated above on page XXX the Roman Emperor had the sole right to resort to force. However, during the Dark Age the Roman Empire disintegrated due to the invasion of the Germanic Tribes. Every free man of these tribes was a warrior. War to the Germanic Tribes was an enterprise to obtain fame and wealth and the charge of their Kings was very different from that of the Roman Emperor. These Kings were not primarily responsible for peace and justice; on the contrary, their duty was in the first place that of warlord. In fact, war to them was the natural state of things and the annual campaign was a part of their living pattern.
Neither was the internal peace fully under the charge of the Kings. For the solution of litigation the subjects had recourse to two alternatives; they could either bring a case before the court, or they could resort to force by exercising their feud right. The feud is a condition of formal and declared hostility that can exist between two persons when one has wronged the other and is unwilling to amend that wrong. The purpose of this force is to coerce the opponent to amend the wrong. This feud right was a fundamental apart of Germanic Law.
When Charlemagne tried to live up to his Roman predecessors he once again attempted to monopolise the use of force. Especially the nobility of that time saw any restriction on their feud right as a breach of their freedom and therefore as an injustice. Here the two radically different legal systems clashed.
After the disintegration of Charlemagne´s Empire due to the struggle between his descendants, the position of the King of the Western Empire was weakened severely. The power vacuum that was created was filled by the dukes. The further this disintegration continued the less willing these local authorities were to subjugate their disputes to a higher authority. The consequence of this was that the disputes between them were again resolved through feuds, with several notable differences:
a) The nobility enforced their own jurisdiction because of which the subordinate population lost their feud rights. This right became an exclusive privilege of the ruling upper class.
b) Because of the invincibility of the strongholds the feuding parties would redirect their force against the defenceless peasantry to compel the opponent to capitulate.
c) The feud developed from a purely legal action into a political military means of coercion until it finally became war.
The main problem was whether feuds could fulfil the requirements of a just war. Primarily the problem revolved around who was to be considered as the right authority. Strictly along the lines of earlier thinkers only the Kings and Emperor were allowed to declare war. Obviously, the actual practice was very different. Although many attempts to banish feud rights failed, certain rules were created by which feuding parties were supposed to adhere. First of all, before resorting to force parties had to strive for a non-violent solution. They were not allowed to use force before the feud was formally and openly declared. A feud that met these requirements was considered in practice to be just.
The theory usually let both parties put forward irrefutable arguments, which allowed them to invoke the just war theory in good faith. The articulation of a just cause was based on vague distinctions such as "fault" or "wrong" that were not further defined and the idea to intend a "better peace" is unclear too. Although a fault or wrong was a thing that existed prior to the decision to declare war and as such some objective measurement was possible, the aim of a better peace was – and still is- immeasurable and solely subject to the expectations and "rational" predictions of the future. The main weaknesses of the tradition lie therefore with the classical distinctions of right authority, just cause and right intention. Especially the purpose of a right intention turns the theory into a teleological one and as war is one of the most socially complex activities of mankind its outcome is impossible to predict beforehand. This is even more true when one considers that rationality is often absent in the heat of battle. As a consequence such precognition is even less likely to be accurate. At the same time the tradition in medieval times and from then on rests on this teleological consideration of a better peace. The classical distinctions of right authority, just cause and right intention have survived to this day.
