‘An impossible hybrid: the structure of the United Nations’ explains the various functions of the conglomeration of organizations, divisions, bodies, and secretariats that make up the UN. The Security Council is the central organ of the UN system and has primary responsibility for the maintenance of international peace and security. The General Assembly is the forum where the 193 member states can make their cases heard. The UN Secretariat serves the other principal organs of the UN and administers the programs and policies laid down by them, with the Secretary-General at its head. The roles of the Economic and Social Council, World Bank, International Monetary Fund, and World Trade Organization are also described.
