The Rules Of War
The Rules of War: Restricting Brutality in Armed Conflict
The rules of war, collectively known as the laws of armed conflict (LOAC) or international humanitarian law (IHL), represent a crucial body of international law designed to mitigate the suffering caused by armed conflict. These rules do not seek to legitimize war itself, but rather to impose certain restrictions on the conduct of hostilities and the treatment of individuals affected by war. The primary aims of LOAC are to protect those who are not, or are no longer, participating in hostilities and to restrict the means and methods of warfare. These objectives are pursued through two main branches of law: the law relating to the protection of victims of conflict and the law governing the conduct of hostilities. The foundational principles of LOAC include distinction, proportionality, military necessity, and humanity. The principle of distinction mandates that parties to a conflict must at all times distinguish between combatants and civilians, and between military objectives and civilian objects. Attacks may only be directed against combatants and military objectives. Civilians and civilian objects are protected from direct attack. The principle of proportionality prohibits attacks which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof, which would be excessive in relation to the concrete and direct military advantage anticipated. Military necessity permits combatants to use only the degree and kind of force, no more than is necessary, to achieve a legitimate military objective. The principle of humanity prohibits the infliction of suffering that is neither necessary for the accomplishment of a legitimate military purpose nor inherent in the nature of warfare.
The Hague Law and the Geneva Law form the twin pillars of LOAC. The Hague Law, primarily stemming from the Hague Conventions of 1899 and 1907, focuses on the means and methods of warfare. It regulates aspects such as the use of certain weapons, the conduct of blockades, and the occupation of enemy territory. The Geneva Law, notably the four Geneva Conventions of 1949 and their Additional Protocols, centers on the protection of victims of war. These conventions provide comprehensive protections for wounded and sick members of armed forces in the field, wounded, sick, and shipwrecked members of armed forces at sea, prisoners of war, and civilians in times of war. The Geneva Conventions also establish a framework for the protection of specific categories of persons and objects, such as medical personnel and installations, cultural property, and civilian infrastructure.
The concept of "combatant" is central to the laws of armed conflict. Under LOAC, combatants are lawful participants in hostilities. They are entitled to treatment as prisoners of war (POWs) if captured. To qualify as a combatant, individuals must meet certain criteria, including being part of an organized armed group, wearing a distinctive sign recognizable at a distance (such as a uniform), carrying arms openly, and conducting their operations in accordance with the laws and customs of war. Unlawful combatants, such as mercenaries or those who do not meet these criteria, may not be entitled to POW status if captured, though they still retain basic protections under international human rights law. The status of civilians is equally crucial. Civilians are protected from direct attack. However, this protection is not absolute. Civilians can lose their protected status if they directly participate in hostilities. This direct participation in hostilities is a complex and often contentious area of LOAC. It generally refers to acts that are specifically calculated to harm the enemy and are carried out in the actual course of hostilities, such as firing weapons, planting mines, or acting as human shields.
The protection of wounded, sick, and shipwrecked members of armed forces is a cornerstone of LOAC. The First Geneva Convention dictates that such individuals, regardless of their nationality, shall be respected and protected in all circumstances. They shall be cared for without discrimination and without any adverse distinction founded on sex, race, nationality, religion, or any other similar criteria. Medical personnel and facilities dedicated to the care of the sick and wounded, including their transport and equipment, are also granted special protection and must not be attacked. Similarly, the Second Geneva Convention extends these protections to those who are wounded, sick, or shipwrecked while in naval warfare. The humane treatment of prisoners of war is codified in the Third Geneva Convention. POWs are not captives of individuals but prisoners of the detaining power. They must be treated humanely, protected from acts of violence or intimidation, and afforded respect for their person and honor. They are entitled to adequate food, clothing, and medical care, and have the right to communicate with their families and to receive relief parcels.
The Fourth Geneva Convention provides comprehensive protection for civilians in times of war, particularly those in occupied territories. It prohibits collective punishment, deportation of protected persons from occupied territory, and the transfer by the Occupying Power of parts of its own civilian population into the territory it occupies. Civilians are entitled to protection from arbitrary detention, torture, and other cruel, inhuman, or degrading treatment. The Convention also outlines the rights and obligations of an occupying power, emphasizing the need to maintain public order and safety while respecting the laws in force in the territory. Additional Protocols to the Geneva Conventions, adopted in 1977, expanded and strengthened protections. Protocol I relates to international armed conflicts and addresses issues such as the definition of combatant status, protection of civilians against the effects of hostilities, and the prohibition of starvation as a method of warfare. Protocol II relates to non-international armed conflicts, applying LOAC principles to situations like civil wars, and providing protections for persons affected by such conflicts, such as those no longer participating in hostilities and those whose liberty has been restricted.
The regulation of weapons and tactics is a significant aspect of the rules of war. LOAC prohibits weapons that cause superfluous injury or unnecessary suffering, or that are inherently indiscriminate. Examples include expanding bullets, chemical and biological weapons, and blinding laser weapons. The principle of distinction also informs the prohibition of indiscriminate attacks, which are attacks not directed at a specific military objective or that employ means or methods of combat which cannot be directed at a specific military objective or whose effects cannot be limited as required by LOAC. The prohibition of starvation as a method of warfare is also a critical tenet, meaning that it is unlawful to attack or destroy objects indispensable to the survival of a civilian population, such as foodstuffs, agricultural areas for the production of food, crops, livestock, drinking water installations and supplies, and irrigation works, for the specific purpose of denying them as sustenance to the civilian population or the enemy, whether in order to starve them out, to force them to move away, or for any other purpose.
The enforcement of LOAC is a complex challenge. International criminal tribunals, such as the International Criminal Court (ICC) and ad hoc tribunals like those for the former Yugoslavia and Rwanda, have been established to prosecute individuals for war crimes, crimes against humanity, and genocide. National courts also have a role in prosecuting war crimes through the principle of universal jurisdiction, allowing them to try individuals for grave breaches of LOAC regardless of where the crimes were committed or the nationality of the perpetrator or victim. The International Committee of the Red Cross (ICRC) plays a vital role in promoting and ensuring respect for LOAC, acting as a guardian of the Geneva Conventions, visiting POWs and other detainees, and facilitating communication between parties to a conflict.
The rules of war are dynamic and evolve to address new challenges posed by contemporary warfare. The rise of non-state armed groups, the use of drones and autonomous weapons systems, and cyber warfare all present new legal and ethical questions that require careful consideration within the framework of LOAC. The interpretation and application of LOAC are subject to ongoing debate and development, but the fundamental aim remains constant: to limit the brutality of war and protect those who bear its brunt. The continuing relevance of LOAC underscores the enduring human desire to mitigate suffering even in the face of organized violence, reflecting a commitment to core humanitarian values. The rules of war are not merely abstract legal principles; they represent a fragile yet essential bulwark against the complete descent into barbarism during times of armed conflict. Adherence to these rules, however imperfect, is a testament to the possibility of maintaining a degree of humanity amidst the devastation of war.
