The Prohibition on the Use of Force in International Law
The prohibition on the use of force is one of the central rules of modern international law. Anchored in Article 2(4) of the United Nations Charter, it restricts states from using or threatening force against the territorial integrity or political independence of other states, while leaving narrow space for Security Council authorization and self-defense. This article explains the legal meaning of force, threats of force, aggression, intervention, occupation, proxy warfare, drones, cyber operations, and humanitarian intervention claims. It examines the UN Charter, the Definition of Aggression, ICJ jurisprudence, self-defense doctrine, collective security, and the relationship between use-of-force law and state responsibility. It also addresses selective enforcement, great-power impunity, Palestine, Ukraine, Iraq, Kosovo, and the future of the Charter framework in an age of hybrid conflict, technological change, and geopolitical fragmentation.
