Background

The United Nations is a 193-member intergovernmental organisation founded in 1945, the main global forum for peace, international law and humanitarian coordination. Its work runs from Security Council diplomacy to peacekeeping missions and specialised agencies that monitor nuclear material, shipping and public health.

The Iran war has tested each layer. On 17 April the International Maritime Organization invoked the Law of the Sea against discriminatory Hormuz tolls and reported 20,000 seafarers and 2,000 vessels trapped in the Gulf; by 10 September its count of attacks on merchant ships had reached 75, with 22 seafarers dead. The IAEA lost continuity of knowledge over Iran's enriched uranium, and the Security Council deadlocked over Hormuz.

Outside the war, UN Tourism lowered its expectation for growth in 2026 international arrivals to 1-2%, against 3-4% in its January outlook. The organisation supplies shared procedures, public records and operational capacity; its binding decisions still depend on agreement among the five permanent members of the Security Council.

Key Issues
Iran nuclear file

Iran's nuclear file reaches the Council

The IAEA, the UN's nuclear watchdog, reported on 4 June that it had lost track of Iran's 440.9 kg stockpile of 60%-enriched uranium after 97 days without inspector access, with about 240 kg in no confirmed location. Around 1 September the agency told members that Iranian nuclear material remained unverified and pressed for urgent entry to the Isfahan plant.

On 9 September the agency's governing board backed referral to the Security Council by 23 votes to 3, with eight abstentions, a step last taken against Iran twenty years earlier. The referral moves the file from the UN's technical body to its political one, where China and Russia, which opposed the board vote, hold vetoes over any binding response.

Security Council

Vetoes block the Council on Iran

On 10 April the Security Council voted 11 to 2 for a resolution calling for the strait of Hormuz to reopen. Russia and China vetoed it, closing the Council's route to a binding demand while Chinese tankers kept transiting under Iranian tolls.

The same two members used the veto again on 17 September, blocking by 11 votes to two the renewal of the UN panel that investigates breaches of Iran sanctions; its mandate expired on 26 September. Britain accused Moscow and Beijing of shielding Tehran. With the panel gone, no body is appointed to keep the Iranian entries on the UN's consolidated sanctions list accurate, and the Council has not elected a chair for the committee that would appoint one.

Lebanon peacekeeping

Peacekeepers come under fire again

Two Ghanaian peacekeepers with UNIFIL, the UN Interim Force in Lebanon, were critically wounded at their base in Qawzah on 6 March, and Ghana lodged a formal protest with Secretary-General António Guterres. On 10 April six peacekeepers were injured and one detained by Israeli forces after a UN convoy was blocked.

On 4 June Serbian peacekeeper Sergeant Milovan Jovanovic died in mortar fire near Marjayoun and two others were wounded; UNIFIL said the attack might be a war crime. The force, deployed under Resolution 1701 with about 10,000 troops, has no enforcement mandate in the zone it patrols. On 22 June its peacekeepers helped reopen roads after Israeli forces pulled back from Debbine.

Common Questions

UNIFIL carries frontline risk

What can UNIFIL do in southern Lebanon?
UNIFIL monitors its mandate area and reports violations, but it cannot compel belligerents to withdraw or stop attacks without stronger Security Council authority.Source: Lowdown
Can UNIFIL stop Israel's advance north of the Litani?
No. UNIFIL has a monitoring mandate under Resolution 1701, not an enforcement mandate. Israeli forces struck north of the Litani Ceasefire line on 26 April 2026 while UNIFIL remained present but unable to compel withdrawal.Source: Lowdown U#82

Reference

How must a country report military self-defence to the United Nations?
Article 51 of the United Nations Charter requires a member exercising self-defence to report its measures immediately to the Security Council.Source: United Nations Charter
Why can Security Council vetoes block United Nations action?
A substantive Security Council resolution cannot pass if any permanent member vetoes it. This can prevent binding action even when most members support a proposal.
How many countries belong to the United Nations?
The United Nations has 193 member states and operates through bodies including the General Assembly and Security Council.Source: United Nations
What is UNIFIL and why are its peacekeepers in Lebanon?
UNIFIL (United Nations Interim Force in Lebanon) is a UN peacekeeping mission deployed under Security Council Resolution 1701, which ended the 2006 Lebanon War. About 10,000 troops from contributing nations including Ghana, France, and Italy monitor the Ceasefire line but have no enforcement authority to stop Israeli operations that breach the buffer zone.Source: UN / Resolution 1701
What is the difference between UNIFIL and the UN Security Council on Lebanon?
UNIFIL is an operational peacekeeping force on the ground in southern Lebanon, created by and answerable to the Security Council under Resolution 1701. The Security Council is the political decision-making body; it sets UNIFIL's mandate but cannot act if any P5 member vetoes a resolution, meaning UNIFIL can be placed in danger while the Council remains deadlocked.Source: UNSC Resolution 1701
What is the United Nations?
The United Nations is an intergovernmental organisation of 193 member states founded in 1945 to maintain international peace and security. It operates through bodies including the Security Council, General Assembly, and a range of peacekeeping and humanitarian agencies.Source: UN Charter
Does the UN have to be notified before a country launches military strikes?
Under Article 51 of the UN Charter, member states that exercise the right of self-defence in response to an armed attack must immediately notify the Security Council. The US filed no Article 51 notification before CENTCOM strikes on Iran in June 2026, a pattern that has drawn criticism from international law scholars and UN observers.Source: UN Charter Article 51 / CENTCOM reporting
Why can't the UN stop the war in Lebanon?
The UN Security Council requires consensus among its five permanent members to authorise enforcement action. The US, which holds a veto, maintains strategic support for Israel, blocking binding resolutions. This P5 deadlock leaves UNIFIL with a monitoring mandate but no enforcement power as Israel's offensive advances beyond the Litani.Source: UNSC
Were UN peacekeepers attacked in Lebanon in 2026?
Yes. Two Ghanaian UNIFIL peacekeepers were critically wounded at their base in Qawzah, southern Lebanon. UNIFIL confirmed the soldiers were inside the base when struck. Ghana lodged a formal protest with UN Secretary-General Guterres demanding an investigation.Source: UNIFIL / Ghana Government
Who leads the United Nations in 2026?
António Guterres is the United Nations Secretary-General. His second five-year term runs through December 2026.Source: United Nations
Why can't the United Nations stop the war between the US and Iran?
The UN Security Council cannot pass binding resolutions without consensus among its five permanent members. The US, which backs Israel and conducted strikes on Iran, holds a veto that blocks any binding condemnation. Russia holds a veto on other disputes. Without P5 agreement the Council can only call for dialogue, not authorise enforcement action.Source: UN Charter / Security Council structure
