About ‘Unwilling or Unable’ Doctrine:

• What It Is: A contested international law doctrine that allows a state to use force against non-state actors (NSAs) within another state’s territory if that state is unwilling or unable to stop them.

• Key Features: Removes the need for state attribution of an attack to invoke self-defence. Justifies cross-border strikes if the host country harbours or fails to act against terrorist groups. Championed by the United States in operations like the 2011 Osama bin Laden raid (Pakistan) and 2014 IS strikes (Syria). Lacks wide state practice or opinio juris, and is not yet customary international law. Opposed by countries like China, Russia, and Mexico for violating sovereignty norms.
