Why the UN's Western Sahara Mission Ended: The Security Council Veto Explained
For 35 years a small UN mission called MINURSO watched over a ceasefire in Western Sahara, a desert territory in north-west Africa claimed by both Morocco and the Polisario Front. On 30 October 2026 the UN Security Council could not agree to extend it: a US draft was vetoed by Russia, and a Russian draft did not get enough votes. The mandate expired on 31 October. Here is how the veto works, why it matters and what India, a top peacekeeping nation, should take from it.
What happened
On 30 October 2026 the Security Council voted on two drafts to keep MINURSO going. A US-drafted text, which would have renewed the mission for a year and renamed it, got 11 votes in favour, 1 against and 3 abstentions. It needed only nine votes, but the vote against came from Russia, a permanent member, so it failed: that is a veto. A Russian-drafted one-year renewal then failed to get the nine votes it needed.
With no new resolution, MINURSO's mandate expired on 31 October 2026. The United States said any drawdown must be orderly and protect UN staff. What replaces the mission, if anything, is still unclear.

The Security Council has 15 members. Ten are elected for two years; five (the US, UK, France, Russia and China) are permanent. A decision on any important matter needs at least nine 'yes' votes, and none of the five permanent members may vote 'no'. One 'no' from any of them blocks the decision, however many others agree. That is the veto. An abstention does not block.
🏠 Everyday analogy
It is like a housing society where any one of five founder members can stop a decision by saying 'no', even if eleven of fifteen members want it.
🇮🇳 Real Indian example
In 2026, eleven countries wanted to renew MINURSO under the US plan, but one 'no' from Russia was enough to stop it.

Official TextArticle 51 and the UN Charter's Voting Rule
Constitution of India, Article 51. Promotion of international peace and security.
The State shall endeavour to (a) promote international peace and security; (b) maintain just and honourable relations between nations; (c) foster respect for international law and treaty obligations in the dealings of organised peoples with one another; and (d) encourage settlement of international disputes by arbitration.
Article 253. Legislation for giving effect to international agreements.
Notwithstanding anything in the foregoing provisions of this Chapter, Parliament has power to make any law for the whole or any part of the territory of India for implementing any treaty, agreement or convention with any other country or countries or any decision made at any international conference, association or other body.
- UN Charter, Article 27(3): decisions on non-procedural matters need the affirmative votes of nine members, including the concurring votes of the permanent members. By long practice, an abstention by a permanent member is not a veto.
- Article 23 of the Charter names the five permanent members; ten non-permanent members are elected for two-year terms.
- Article 51(b) and (c) of India's Constitution ask the State to maintain just and honourable relations between nations and foster respect for international law, which shapes India's support for UN peacekeeping.

Defenders of the veto say
- It keeps the great powers inside the UN
- It forces compromise before action
- Without it, decisions could be ignored by major powers
- Any reform needs P5 consent under Article 108
