The Responsibility to Protect (R2P) doctrine holds that sovereignty is not a shield for mass atrocities.

When a State is unable or unwilling to protect its population from genocide, war crimes, ethnic cleansing, or crimes against humanity, the international community has a responsibility to step in—starting with diplomatic and humanitarian measures, and, as a last resort, collective action through the UN Security Council.

R2P reframes sovereignty as responsibility, not absolute control.

Medium–High yield in Public International Law. Commonly tested in problems involving humanitarian intervention, use of force, UN Security Council authority, and the limits of non-intervention. 

A frequent trap is assuming unilateral military action is allowed under R2P—it is not; Security Council authorization is key.

United Nations Security Council Resolution 1973 (2011) – Libya (Official UN Documents).

In response to mass violence against civilians under the Gaddafi regime, the UN Security Council invoked R2P and authorized member States to take “all necessary measures” to protect civilians, including the establishment of a no-fly zone. 

This marked the first major operational use of R2P to justify collective military action aimed at civilian protection rather than regime change.

🥜 R2P allows collective international action—authorized by the UN Security Council—when a State fails to protect its people from mass atrocities.
