Is the United Nations still relevant?

The UN's relevance is debated more fiercely than ever — I'll gather current assessments of its role and challenges.

Short answer: Yes — but its relevance is uneven, contested, and increasingly conditional on reform.

The answer depends on what you mean by "relevant." If you mean "does it still matter as a global institution that affects diplomacy, humanitarian outcomes and international norms?" — most world leaders and publics still say yes. If you mean "is it effective at stopping the major wars and geopolitical crises of the moment?" — its record is widely seen as weak and paralyzed.

1. Why many still say the UN is indispensable

a) Universal forum where everyone still shows up
After six days of speeches at the 81st UN General Assembly General Debate in September 2026, Assembly President Khalilur Rahman said leaders confronted a world of conflict, stalled development and inequality, but heard a common conviction: "the United Nations remains indispensable".

That popularity is itself a measure of relevance. In September 2026, 194 speakers took the floor, including 113 Heads of State and Government, one crown prince, 11 Vice Presidents and others. As Chicago Council analysis notes: "its more than 190 member states, with only a few exceptions, are sending representatives" and "The vast majority are sending heads of state, presidents, or prime ministers", a "clear indicator that the United Nations is widely viewed to be politically relevant and an important platform".

The Chicago Council also notes public opinion remains net-positive:

> Most publics in the 25-nation 2025 Pew Global Attitudes Survey hold net-positive views of the United Nations

And that perception makes it a "still-useful venue for international contestation—and a tool for nations seeking international power and prestige".

b) The "other UN" — agencies doing work in the field

Analysts often describe the UN as "a tale of two institutions" — one a gridlocked political body, and the other a network of agencies doing "real, important work in the field".

That field work includes:

In a fractured world, its defenders argue its "universal character, institutional capacities, implementation muscle, and broad-based legitimacy as a venue for dialogue and diplomacy are irreplaceable".

c) Preventing great-power war and setting norms

One school argues the original purpose was not to stop all wars, but to prevent another world war between great powers: "The United Nations is still relevant if one keeps in mind the core purpose of its founding: to prevent another world war between the great powers" and that it has "lasted longer than both of those failed attempts is, of itself, an accomplishment. But that the world has not witnessed another war on the scale of either the First or Second World Wars in the 80 years...is a testament to its success".

The UN also remains central to climate pledges (Nationally Determined Contributions under the Paris Agreement), sustainable development goals, and emerging governance of AI — 128 delegations raised AI in the 2026 debate, up from only five four years earlier.

2. Why relevance is questioned

a) Security Council paralysis and the veto
The most common criticism:

> "Increasingly, the United Nations is seen as an ineffective body in managing conflicts in the world. The problem is the veto power of the five permanent members of the United Nations Security Council"

Example cited in 2025: "While all 14 other members of the UNSC had voted in favour of the resolution [for Gaza ceasefire and release of hostages], the United States, as one of the five permanent members of the UNSC, vetoed the draft". Russia has repeatedly vetoed resolutions on Syria, and China joined Russia to veto on Syria, Myanmar and Zimbabwe.

This leads to "a constrained role in maintaining international peace and security" with a "mixed track record, intervening successfully in some crises (e.g., Somalia), but not in others (e.g., Rwanda and Gaza)".

b) Representativeness and legitimacy crisis

c) Financial and structural strain
"Undercut by financial shortfalls, US retrenchment, and growing geopolitical divides", the UN's ability is "radically diminished by the United States' decision to delay critical budgetary support and put caps on its contributions to UN peacekeeping" and the US decision to withdraw from the Paris Agreement and World Health Organization "has disrupted progress on two of the greatest challenges". Another summary notes the UN is in "clear crisis. The United States has retracted essential financial contributions, plunging the organization into financial freefall. The Security Council is deadlocked politically, and its composition, essentially frozen since 1945, has undercut its global legitimacy".

Critics note "Decades of negotiations on Security Council reform have not produced real outcomes, other than frustration and cynicism" and that bureaucracy and slow decision-making reduce effectiveness.

3. The central debate: Reform or decline

At the 2025-2026 debates, observers noted:

> "A recurring question throughout the debate was not whether the United Nations should exist, but whether it can produce results"

President Rahman summarized outside perception: "Outside these walls, people are not asking whether the United Nations still exists" — implying they are asking whether it delivers.

Reform proposals center on:

Without reform, analysts warn of alternatives: "We may find ourselves in a mini-lateral world of issue-specific, politically-driven alliances of convenience, a 'world minus one' configuration where the United States stands outside a measure of global consensus", or a system where "China takes up the reins". China's own public supports greater UN engagement — 68% say China's participation has been very important and 77% agree China should be more willing to make decisions within the UN framework.

Bottom line

The UN in 2026 is both:

Many experts conclude, as one put it, salvaging its "financially-starved humanitarian capabilities should be the most urgent task" even while political deadlock persists. Its future relevance will likely depend less on whether it exists and more on whether members allow the "UN80" style reforms to make it "changes realities on the ground" rather than just resolutions and speeches.
