War crime

A war crime is a serious violation of the laws of war. These laws are also called international humanitarian law (IHL). They provide a set of rules for people fighting in armed conflicts. When these rules are broken, individuals can be held criminally responsible. This means that single people, not just entire nations, can be punished under international law.

War crimes involve many different types of harmful actions. Combatants may commit crimes by intentionally killing civilians or taking hostages. Other examples include torture, pillaging, or the conscription of children into the military. Some crimes involve the use of deception, which is called perfidy. Perfidy occurs when a person uses a flag of truce to trick an enemy during an attack. Additionally, the use of chemical and biological weapons is prohibited by several international agreements.

There are specific rules regarding how soldiers should behave during combat. For instance, the 1907 Hague Convention forbids punishing enemy spies without a trial. The Geneva Conventions also provide protections for people who are no longer fighting. Protocol I of the Geneva Conventions forbids attacking parachutists who have ejected from a disabled aircraft. It also protects those who have landed after surrendering. While wearing enemy uniforms for espionage is a legitimate ruse, using them to fight or assassinate people is unlawful perfidy.

The formal concept of war crimes has developed over many years. In 1863, the Union Army used the Lieber Code during the American Civil War. Later, the Hague Conventions of 1899 and 1907 established rules for international warfare. The 1899 Geneva Conventions also helped define new war crimes. These rules allowed states to exercise universal jurisdiction over criminals. In the late 20th and early 21st centuries, international courts expanded these definitions to include civil wars.

History shows how these laws are applied in international courts. After World War II, the Nuremberg and Tokyo Trials were held to judge leaders. These trials established the Nuremberg principles, which define war crimes clearly. The Tokyo Trials ruled that the attack on Pearl Harbor was a war crime. This was because the attack went beyond military necessity and occurred while the nations were at peace. More recently, the International Criminal Court has handled new types of cases. In 2016, the court convicted Jean-Pierre Bemba Gombo for sexual violence.

Sometimes, there is debate about whether certain actions are war crimes. This is often called "victor's justice" when only the losers are punished. For example, the Allies did not prosecute German leaders for bombing cities like Warsaw or Rotterdam. They also did not prosecute the Japanese for attacks on Chinese cities. During World War II, there was no specific treaty protecting civilians from aircraft attacks. Therefore, the strategic bombing of cities like Dresden or Tokyo was not officially ruled a war crime.

Modern law tries to balance military necessity with the protection of people. Military necessity allows for the destruction of targets that are essential to war. For example, an attack on an ammunition depot is allowed even if a farmer is nearby. The farmer is not the object of the attack, so the action may be permissible. However, killing innocent people for revenge is never allowed. The law seeks to prevent unnecessary suffering and to protect those who are not participating in the fight.
