United Nations
The near-universal forum where sovereign states manage peace, rights and collective problems.
Purpose
The United Nations exists to keep war between states within bounds and to give sovereign governments a permanent place to negotiate instead of fight. Founded on the principle of sovereign equality, it maintains international peace and security, develops friendly relations among nations, and coordinates action on shared problems from famine to disease. It is not a world government: it has no power to tax or to legislate over citizens, and it acts only through the consent and contributions of its member states. Its authority rests on a treaty, the Charter, which member states voluntarily accept, and its greatest asset is legitimacy — the sense that its decisions speak for the community of nations as a whole.
Structure — organs & roles
General Assembly
The plenary chamber where every member state has one vote; debates any issue and adopts non-binding resolutions and the budget.
Security Council
The organ with primary responsibility for peace and security; its five permanent members hold a veto and its decisions bind all members.
Secretariat
The permanent civil service headed by the Secretary-General that administers programmes, mediates disputes and services the other organs.
Economic and Social Council
Coordinates the economic, social and development work of the UN and its network of funds and specialised agencies.
International Court of Justice
The principal judicial organ that settles legal disputes between states and gives advisory opinions to UN bodies.
Funds, programmes and specialised agencies
Semi-autonomous bodies such as UNICEF, UNHCR, the WHO and the World Bank that deliver the UN's operational work on the ground.

Mandate & Incentives
Mandate
The UN's authority flows from its Charter, a treaty that binds its members to settle disputes peacefully and to refrain from the threat or use of force. Only the Security Council may authorise coercive measures — sanctions or military action — and its decisions are legally binding on all states. The General Assembly, by contrast, can debate anything but its resolutions carry only moral and political weight. The organisation is expressly barred from intervening in matters that are essentially within a state's domestic jurisdiction, a limit that constantly collides with its human-rights ambitions.
Incentives
The UN is pulled between the interests of its most powerful members and the aspirations of the majority, and it survives by never straying too far from great-power consensus. Because the permanent five can veto any enforcement action, the Security Council goes silent precisely when their interests clash, which is often. The Secretariat guards its neutrality and access, wary of being seen as the instrument of any bloc, while agencies compete for the voluntary funding that keeps their programmes alive. The result is an institution that is indispensable for legitimacy yet chronically dependent on the goodwill of states that can withhold money or cooperation at will.
