Maintenance of international peace and security
The main function of the United Nations is to preserve international peace and security. Chapter 6 of the Charter provides for the pacific settlement of disputes, through the intervention of the Security Council, by means such as negotiation, mediation, arbitration, and judicial decisions. The Security Council may investigate any dispute or situation to determine whether it is likely to endanger international peace and security. At any stage of the dispute, the council may recommend appropriate procedures or methods of adjustment, and, if the parties fail to settle the dispute by peaceful means, the council may recommend terms of settlement.
The goal of collective security, whereby aggression against one member is met with resistance by all, underlies chapter 7 of the Charter, which grants the Security Council the power to order coercive measures—ranging from diplomatic, economic, and military sanctions to the use of armed force—in cases where attempts at a peaceful settlement have failed. Such measures were seldom applied during the Cold War, however, because tensions between the United States and the Soviet Union prevented the Security Council from agreeing on the instigators of aggression. Instead, actions to maintain peace and security often took the form of preventive diplomacy and peacekeeping. In the post-Cold War period, appeals to the UN for peacekeeping and related activities increased dramatically, and new threats to international peace and security were confronted, including AIDS and international terrorism.
Notwithstanding the primary role of the Security Council, the UN Charter provides for the participation of the General Assembly and nonmember states in security issues. Any state, whether it is a member of the UN or not, may bring any dispute or situation that endangers international peace and security to the attention of the Security Council or the General Assembly. The Charter authorizes the General Assembly to “discuss any questions relating to the maintenance of international peace and security” and to “make recommendations with regard to any such questions to the state or states concerned or to the Security Council or to both.” This authorization is restricted by the provision that, “while the Security Council is exercising in respect of any dispute or situation the functions assigned to it in the present Charter, the General Assembly shall not make any recommendation with regard to that dispute or situation unless the Security Council so requests.” By the “Uniting for Peace” resolution of November 1950, however, the General Assembly granted to itself the power to deal with threats to the peace if the Security Council fails to act after a veto by a permanent member. Although these provisions grant the General Assembly a broad secondary role, the Security Council can make decisions that bind all members, whereas the General Assembly can make only recommendations.
