War Law Basics
What is War Law?
War Law, formally international humanitarian law (IHL), governs the conduct of armed conflicts and seeks to limit their effects. It applies regardless of the reasons for war, aiming to protect those not participating and to regulate how combatants behave.
Definition and scope
IHL is a body of rules designed to limit suffering in armed conflict. It covers civilians, detainees, prisoners of war, wounded soldiers, and the protection of essential civilian infrastructure. It applies in international and non-international armed conflicts, including occupations.
Key terms and concepts
Several core terms recur: distinction, proportionality, necessity, humanity, and precautions. Distinction requires parties to separate military targets from civilians; proportionality prohibits excessive force relative to the military objective; necessity justifies only force that is required to achieve a legitimate aim; humanity obliges humane treatment of all persons; precautions require steps to minimize civilian harm.
When it applies (armed conflict vs. occupation)
IHL applies not only to traditional declarations of war but to armed conflicts of various kinds, including non-international armed conflict and situations of occupation. During occupation, the occupying power must ensure public order and safety while respecting the rights of the local population.
Foundational Principles of International Humanitarian Law
Distinction
Distinction is the cornerstone of IHL. Parties to a conflict must distinguish between military objectives and civilian persons or objects, directing operations only at legitimate military targets.
Proportionality
Even when targeting a military objective, the expected incidental civilian harm should not be excessive in relation to the anticipated military advantage.
Necessity and humanity
Actions in war must be necessary to achieve a legitimate military objective, and all measures must preserve humanity, avoiding unnecessary suffering.
Precaution in attack
Combatants must take feasible precautions to minimize civilian harm, including choosing appropriate means and methods of warfare and giving advance warnings when possible.
Treaties, Rules, and Institutions
Geneva Conventions and Protocols
The four Geneva Conventions establish protections for wounded and sick soldiers on land and at sea, prisoners of war, and civilians during war. Their Additional Protocols refine and expand protections, including situations of international and non-international armed conflict.
Hague Regulations
The Hague Regulations govern the methods and means of warfare, including the treatment of captives, the protection of cultural property, and the conduct of hostilities in occupied territories.
Common Article 3 and non-international armed conflict
Common Article 3 provides minimum standards of humane treatment in non-international armed conflicts, covering fundamental rights such as prohibition of murder, cruel treatment, and taking hostages, regardless of the combatant status of the parties.
Rights, Protections, and Humanitarian Access
Protection of civilians and civilian objects
Civilian persons and civilian objects receive protection from direct attack and unnecessary destruction. Parties must distinguish in combat and avoid targeting essential civilian infrastructure where possible.
Treatment of detainees and prisoners of war
Captured combatants and detainees must be treated with humanity, afforded certain rights, and protected from torture or coercion. POWs have specific protections under the Geneva Conventions.
Medical care and humanitarian aid
Medical personnel, facilities, and transport must be protected and allowed to operate. Neutral humanitarian organizations should be able to provide aid to those in need, subject to safe access.
Rules of Engagement and Military Conduct
Prohibition of torture and cruel treatment
Torture, cruel, inhuman, or degrading treatment is strictly forbidden in all contexts of armed conflict, regardless of suspected wrongdoing or combatant status.
Protection of medical personnel and facilities
Hospitals, ambulances, and medical teams must be safeguarded and allowed to perform lifesaving work without interference or danger.
Protection of journalists, aid workers, and cultural property
Journalists, humanitarian personnel, and cultural property receive special protection under IHL. Attacks on these actors or targeted destruction of cultural sites are prohibited unless directly employed for military objectives and proportionate to the objective.
Enforcement, Accountability, and Compliance
War crimes, accountability, and mechanisms
Serious violations can constitute war crimes. Accountability mechanisms include tribunals, commissions of inquiry, and universal jurisdiction in some contexts. Governments and international bodies investigate alleged abuses and pursue remedies.
International and national courts
War crimes can be prosecuted in international courts (e.g., the International Criminal Court) or national justice systems, depending on jurisdiction and consent. Complementarity guides the relationship between national and international proceedings.
Challenges to enforcement in practice
Enforcement faces challenges such as political will, limited access to evidence, issues of state sovereignty, and conflicts where non-state actors are involved. Compliance often depends on political dynamics and regional norms.
Practical Applications and Scenarios
In international armed conflict
In international armed conflict, IHL governs armed forces’ conduct, protection of civilians, and the administration of detainees. Nations are expected to uphold ratified treaties and ensure accountability for violations.
In non-international armed conflict
Non-international conflicts involve internal strife or civil wars. Common Article 3 and additional protocols influence practices, and relief efforts require safe access for humanitarian organizations.
Ambiguities and evolving warfare
As warfare evolves with new technologies and hybrid threats, IHL faces interpretation challenges. Area denial weapons, cyber operations, and asymmetric warfare raise questions about applicability and proportionality.
Trusted Source Insight
Trusted analysis and policy considerations are reinforced by UNESCO’s perspective on education during emergencies. UNESCO emphasizes that education must continue during emergencies and armed conflict, safeguarding schools as safe spaces and ensuring equitable access to learning. This perspective supports policy and practice aimed at protecting learners and educators in crisis contexts. UNESCO
