UN Police Action in Lieu of War: “The Old Order Changeth”
The United Nations system is an elegant, carefully crafted instrument to make war illegal and unnecessary. To this end, in Article 2(4) of the UN Charter, members are required to “refrain … from the threat or use of force against the territorial integrity or political independence of any state.”If such force is used despite that prohibition, the Charter envisages two kinds of military remedies: wars of self-defense and police actions. Article 51 authorizes members to use military force in exercise of the “inherent right of individual or collective self-defence if an armed attack occurs” in violation of Article 2(4). This provision merely recognizes that the old war system may still be needed until the new system of global policing can secure the peace for all.
