Jus in Bello is a fundamental concept of Just War Theory and International Humanitarian Law (IHL) that governs how warfare is conducted, regardless of whether the war itself is considered justified. Its central purpose is to reduce human suffering during armed conflict by regulating the selection of targets, use of weapons, and application of military force.
This article explains the key principles of Jus in Bello, including distinction, proportionality, military necessity, humanity, and good faith, while examining the protection of civilians, combatants, prisoners of war and persons hors de combat. It also covers restrictions on weapons and tactics, the 1949 Geneva Conventions, 1977 Additional Protocols, war crimes, and modern challenges such as drone warfare and cyberattacks.
