Is the United Nations still relevant?

Is the UN still relevant? I'll gather up-to-date analysis on its role, effectiveness, and reform debates.

The United Nations is still relevant, but its relevance is increasingly contested - and increasingly selective.

The debate has intensified as the organization marked its 80th anniversary in 2025-2026. The question is not new, but it has "sharpened dramatically as the organization marks its eightieth year"and the high-level week of the 81st General Assembly in September 2026 unfolded against "severe global structural strain".

There are two different UNs being judged:

1. Why many say it is still indispensable

> The United Nations remains indispensable to international co-operation and humanitarian action, but an organisation created in 1945 can’t meet today’s challenges if its funding, leadership and ability to act remain vulnerable to the political interests of powerful governments.

Proponents argue:

a) Humanitarian and development work has no substitute. In 2024 the UN:

It also coordinates health, climate, SDGs, and rights work - supporting 170 countries in implementing their nationally determined contributions to reduce emissions and advancing initiatives to eliminate violence against women and girls.

b) Normative and diplomatic forum. Even critics note "There is no realistic sign that the organization is about to vanish". The UN provides the only universal membership forum of 193 states, where, as one analysis notes, "the organisation can’t deliver what its 193 member states are unwilling or unable to support"but where norms, treaties like the Paris Climate Accord, and legitimacy are produced. The 2024 Summit of the Future adopted the Pact for the Future, a landmark agreement to revitalize international cooperationincluding calls for Security Council reform.

c) Public legitimacy remains relatively high. A Pew Research Center survey in September 2025 covering 31,938 adults in 25 countries found that a median of 61 percent of adults had a favorable view of the world organization, while only 32 percent had an unfavorable one. In the US, 57 percent of Americans held a positive view. A Spring 2026 survey across 37 countries still found a median of 55% have a favorable opinion.

The view summarized by supporters is: "We need the United Nations. What we need is a UN better equipped to do its job".

2. Why many say it is losing relevance

a) Security Council paralysis. The central criticism is the gap between ambitions and capacity:

> "This widening gulf between the United Nations’ institutional ambitions and its practical capacity to enforce international norms, prevent aggression, and deliver emergency relief has reignited debate over whether the UN system can effectively manage an increasingly multipolar, fragmented world".

Specific mechanisms:

Indian External Affairs Minister S Jaishankar argued the organisation has become "largely disconnected from major international decision-making because of persistent deadlock within the UN Security Council", and has "struggled to play a meaningful role in some of the world's most pressing challenge".

Critics point to "repeated failures of the United Nations in preventing conflicts such as Ukraine, Gaza, and Sudan along with veto paralysis"and that "The UN has been ineffective in major crises such as Ukraine, Israel-Gaza, Syria, and Sudan often reduced to passing symbolic resolutions"with earlier failures in Rwanda (1994) and Bosnia (1990s).

At UNGA 2026, observers noted the institutional "moment" has clearly faded in 2026, making this year’s UNGA a relatively low-profile political spectacle and more of a regular venue for bilateral diplomacy and speeches about crises instead of the central mechanism for resolving them.

b) Financial vulnerability. The UN’s financial dependence on a handful of countries, especially the United States (contributing around 22% of its regular budget), makes it vulnerable to political pressures. The United States owes the UN roughly $4 billion, arrears that Guterres warns have brought the organization to the brink of "imminent financial collapse". US humanitarian funding to the UN has fallen by roughly four-fifths in three years, with broader cuts including $800 million already appropriated for peacekeeping rescinded.

c) Structural mismatch with 2026 reality. "The Security Council's permanent membership reflects the world of 1945, not the world of 2026". As a result, the critique is that the organization increasingly exists "as a stage without authority, a forum without consequence, and a system that watches crises unfold without the power to prevent or resolve them".

A more nuanced analysis from Carnegie describes not decline but "decomposition" :

> The UN is not declining so much as decomposing—what was a one-stop shop for peace and security is becoming a bundle of boutiques.
> What was a one-stop shop for peace and security is becoming a bundle of boutiques. This is not the first time this has happened.

In this view, great powers are "picking which parts of the UN to contract for their own diplomatic purposes and leaving the rest to fend for themselves" - an "à la Carte Peace" model that pulls the system apart at the seams.

3. Reform or further irrelevance?

The consensus among analysts, even those defending the UN, is that reform is essential. Proposed reforms include:

As noted in one medium analysis, the UN "confronts an existential crisis, caught between an outdated post-war structure and the complex realities of a multipolar 21st century" where "Security Council's paralysis, driven by the veto power, undermines its core mission, while its humanitarian and development agencies perform vital work".

Bottom line: If relevance is measured by the ability to stop wars between great powers or veto-wielding states, the UN looks increasingly irrelevant - by design, since it was "not created to lead mankind to heaven but to save humanity from hell" and requires great power unanimity to act. If relevance is measured by feeding the hungry, sheltering refugees, keeping peace where peace exists, setting global norms on climate, health and development, and providing the only universal forum where all states can talk, it remains - as Pew polling shows - broadly supported and without a viable replacement. What has changed is that relevance is no longer automatic or comprehensive; it must be earned issue-by-issue, and will depend on whether member states allow reform of finance, veto restraint, and Security Council representation.
