- Explain the historical context for the UN's founding (1945) and how it differs from the failed League of Nations.
- Identify the six principal organs of the UN and the role of each.
- Describe the composition of the Security Council, the powers of the P5, and the consequences of the veto.
- Distinguish between binding Security Council resolutions and non-binding General Assembly resolutions.
- Summarize the 17 Sustainable Development Goals and identify two that a chosen country is making real progress on.
Key Concepts
The United Nations was created in 1945 by 50 founding states determined not to repeat the catastrophe of the League of Nations, which had failed to prevent World War II. The UN Charter, signed in San Francisco on June 26, 1945, took effect that October. Today the UN has 193 member states — effectively every recognized sovereign country except the Vatican City and a handful of disputed territories.
The UN's stated purposes are four: to maintain international peace and security, to develop friendly relations among nations, to achieve international cooperation in solving economic, social, cultural, and humanitarian problems, and to be a center for harmonizing the actions of nations. Its work happens through six principal organs created by the Charter, each with distinct authority.
The most powerful and most criticized organ is the Security Council. Of its 15 seats, five are permanent — held by the United States, United Kingdom, France, Russia, and China — and ten rotate among other member states for two-year terms. Each P5 member has a veto that can block any substantive resolution. The veto is the structural reason the Security Council cannot enforce action against a P5 country (or its close ally), and it has been wielded over 250 times.
In 2015 the General Assembly adopted the Sustainable Development Goals (SDGs) — 17 global targets to be reached by 2030, ranging from "no poverty" to "climate action" to "peace, justice, and strong institutions." Each country reports voluntarily on its own progress; the UN tracks progress on 232 indicators. The SDGs replaced the earlier (2000-2015) Millennium Development Goals.
The Six Principal Organs
General Assembly
All 193 members, one vote each. Adopts non-binding resolutions, sets the budget, elects the Secretary-General. Meets annually in New York.
Security Council
15 members (5 permanent + 10 rotating). The only organ that can authorize binding force or sanctions. P5 veto applies to substantive votes.
Economic and Social Council
54 members. Coordinates the UN's specialized economic, social, and humanitarian agencies; reviews national reports on the SDGs.
Trusteeship Council
Created to supervise decolonization of trust territories. Suspended in 1994 after Palau achieved independence; could be repurposed.
International Court of Justice
The UN's principal judicial organ. 15 judges sit in The Hague. Settles disputes between states (with their consent) and issues advisory opinions.
Secretariat
The UN's civil service. Roughly 37,000 staff worldwide. Headed by the Secretary-General, currently António Guterres (Portugal), serving since 2017.
Country Case Studies
United States
P5 host nationThe US hosts UN headquarters in New York and was one of the chief architects of the post-war system. It is the largest single contributor to the regular budget and one of two P5 members (with the UK) that has used the veto rarely in recent years.

Russia
P5 inheritorRussia inherited the Soviet Union's permanent Security Council seat in 1991 without a vote. It has used the veto more than any other P5 member, often blocking resolutions on Syria and Ukraine.

Switzerland
Geneva — UN's second HQSwitzerland was famously neutral and only joined the UN in 2002. Yet Geneva has long hosted the European headquarters of the UN, including the Human Rights Council, WHO, ILO, UNHCR, and UNCTAD.

Kenya
UNEP and UN-Habitat hostNairobi is the only UN headquarters in the Global South. It hosts UNEP (the UN Environment Programme) and UN-Habitat, reflecting an effort to balance the geography of the UN system.
Country page →Discussion Questions
- The Security Council's P5 veto reflects the geopolitical reality of 1945. What would a more representative Security Council look like, and what countries would have the strongest claim to a permanent seat today?
- The General Assembly passes hundreds of resolutions each year, all non-binding. Why does the UN bother with non-binding resolutions, and what do they actually accomplish?
- The UN has a budget roughly the size of the city of San Diego's. Is the organization underfunded for its mandate, or is the budget about right given how much it actually does?
- Pick one Sustainable Development Goal. Identify three countries making real progress on it and one that is moving in the wrong direction. What explains the difference?
- The UN failed to prevent the genocides in Rwanda (1994) and Srebrenica (1995). What changes to the system would have allowed it to act in those cases, and what new risks would those changes create?
Classroom Activities
Mock Security Council
Students roleplay the 15 current Security Council members debating a current crisis (Ukraine, Sudan, climate, etc.). Each P5 member can veto. The session ends with a recorded vote and a written reflection on what the veto changed.
SDG Country Report Card
Each student picks one country and one SDG. Using the UN SDG dashboard, they write a one-page report card on that country's progress, citing at least three indicators.
