Dan Trabue of Payne Hollow and I have been exchanging views about the concept of a 'Just War', and rather then leave them in comments, I thought I would start a new post. The concept interests me from both legal and historical aspects.
Just as peoples, cultures and nations develop laws to regulate their civil affairs, they also develop laws and codes and traditions that determine how and when they may make war. Implicit in these codes is the concept of a 'just war', i.e. war that may be waged without putting a moral onus on the people / nation waging it. In the Western tradition, the first systematic discussion of 'just war' was written by St. Thomas Aquinas in the Summa Theologica. He identifies three requirements for war to be considered just:
In order for a war to be just, three things are necessary. First, the authority of the sovereign by whose command the war is to be waged. For it is not the business of a private individual to declare war, because he can seek for redress of his rights from the tribunal of his superior...
Secondly, a just cause is required, namely that those who are attacked, should be attacked because they deserve it on account of some fault. Wherefore Augustine says (QQ. in Hept., qu. x, super Jos.): "A just war is wont to be described as one that avenges wrongs, when a nation or state has to be punished, for refusing to make amends for the wrongs inflicted by its subjects, or to restore what it has seized unjustly."
Thirdly, it is necessary that the belligerents should have a rightful intention, so that they intend the advancement of good, or the avoidance of evil. Hence Augustine says (De Verb. Dom. [The words quoted are to be found not in St. Augustine's works, but Can. Apud. Caus. xxiii, qu. 1): "True religion looks upon as peaceful those wars that are waged not for motives of aggrandizement, or cruelty, but with the object of securing peace, of punishing evil-doers, and of uplifting the good."...
More recently, St. Thomas' principles have been expanded to seven requirements by those who support the concept of a just war:
- A just war can only be waged as a last resort. All non-violent options must be exhausted before the use of force can be justified.
- A war is just only if it is waged by a legitimate authority. Even just causes cannot be served by actions taken by individuals or groups who do not constitute an authority sanctioned by whatever the society and outsiders to the society deem legitimate.
- A just war can only be fought to redress a wrong suffered. For example, self-defense against an armed attack is always considered to be a just cause (although the justice of the cause is not sufficient--see point #4). Further, a just war can only be fought with "right" intentions: the only permissible objective of a just war is to redress the injury.
- A war can only be just if it is fought with a reasonable chance of success. Deaths and injury incurred in a hopeless cause are not morally justifiable.
- The ultimate goal of a just war is to re-establish peace. More specifically, the peace established after the war must be preferable to the peace that would have prevailed if the war had not been fought.
- The violence used in the war must be proportional to the injury suffered. States are prohibited from using force not necessary to attain the limited objective of addressing the injury suffered.
- The weapons used in war must discriminate between combatants and non-combatants. Civilians are never permissible targets of war, and every effort must be taken to avoid killing civilians. The deaths of civilians are justified only if they are unavoidable victims of a deliberate attack on a military target.
Within fairly broad limits, I accept these principals and believe that they have been upheld by the United States in most of our wars (the Mexican War and the Spanish-American War are notable exceptions). However, there are some points that I question:
Requirement (2) seems to prohibit guerilla / partisan warfare of the sort waged by Americans during our War for Independence, by the Spanish during their guerilla war against Napoleon, or by the followers of Mao during World War II and China's long civil war. Further, "legitimate" authority may well be subject to interpretation.
Requirement (3) seems clearly to prohibit preemptive action. I realize that this concept is especially controversial of late, but there are cases where preemptive action makes logical sense. For example, if the US had detected the Japanese fleet steaming toward Hawaii on December 6, 1941, it seems reasonable that the United States could have attacked that fleet even though Japan had not yet taken any offensive action.
Requirement (3) also seems to preclude peace keeping or police actions. For example, the Janjaweed militia committing genocide in Darfur has not caused any injury to the United States. Therefore, we could not wage 'just' war against them even if we so desired.
Requirement (4) interests me because it hearkens back to the medieval concept of 'guilty in defense' (see The Life of King Henry V, Act III, scene 3). The problem lies in who should decide when a cause has become hopeless. Should Britain have surrendered along with France in 1940? Her cause seemed hopeless. Should the Soviet Union have surrendered when the Nazis were mere miles from Moscow? If the USSR had launched a massive nuclear attack against the United States, should we have refrained from retaliation?
Requirement (6) is dangerous and, frankly, bloody stupid. Use of minimum force will almost certainly prolong a war and ultimately cause more devastation and loss of life. Further, it implies 'tit for tat'. No nation or people can reasonably be expected to accept such a state of affairs.
Requirement (7) is a nice sentiment, but it is nearly impossible in the modern world because nation-states make war. Thus, their civilians become targets to the extent that they support the state's ability to make war. Workers in munitions plants, civilian members of the state's military apparatus, and even workers not directly employed in war-related industries (such as farmers, miners, railway workers, etc) can become legitimate targets.
Naturally, I do not believe that the United States should make war rashly or maliciously. Diplomacy should be pursued to the greatest extent possible without sacrificing our national goals. If diplomacy fails, there are other options such as economic embargoes and attempts to get other nations to align with us to bring pressure to bear on the offending party. However, these methods have there limitations, and when they fail, force becomes the only remedy other than surrender.
It goes without saying that the United States should wage war with as much charity and mercy as possible. We should not set out to bomb civilians, raze entire cities, or inflict catastrophic damage on the enemy. Further, we have laws and rules governing the conduct of our military personnel both on the battlefield and in occupied territory, and I believe that such rules should be strictly enforced. However, the ultimate aim of winning cannot be sacrificed if the national security of the United States is at risk, nor should American lives be lost needlessly to spare the lives of the enemy. Our goal should always be to establish a just and lasting peace, but we should always be the victor.
