International humanitarian law and peace: A brief overview

International humanitarian law (IHL), also known as the law of armed conflict, seeks to limit the humanitarian impact of war by regulating the conduct of hostilities and protecting those not or no longer participating in combat. IHL does not prevent war, nor is that its role. IHL is only one part of the fabric of international law, other parts of which (jus ad bellum) govern the legality of war itself. However, IHL plays an essential role in mitigating suffering and fostering conditions that may facilitate a return to peace. This article examines the long-standing debate over whether IHL inadvertently legitimizes war or whether it can actually contribute, indirectly, to peace by imposing humanitarian constraints on conflict. It explores how adherence to IHL can preserve human dignity and support post-conflict reconciliation. Ultimately, while IHL does not prevent war, its strict application helps to reduce war's brutality and create pathways for sustainable peace.
