Is the United Nations still relevant?

Is the UN still relevant? I'll gather the latest evidence on its global impact and its current challenges.

Yes — but its relevance is increasingly contested and conditional.

There is no consensus that the UN is obsolete, but almost all observers agree its effectiveness is sharply limited and it is at a crossroads as it turns 80.

Why many still say the UN is relevant

1. It is the only universal platform
The UN Office of Legal Affairs argues the UN "remains a unique platform to address contemporary global challenges, being, as it is, the only universal platform with the mandate to maintain international peace and security".

On the commemoration of its 75th anniversary, the General Assembly agreed: "There is no other global organization with the legitimacy, convening power and normative impact of the United Nations".

As one 21st century assessment put it, the UN is still relevant if one keeps in mind the core purpose of its founding: "to prevent another world war between the great powers".

Speakers at the General Assembly debate have called it an "indispensable 'family of nations' that had nurtured countries in search of equality, peace and prosperity".

2. Humanitarian, development and normative work outside the Security Council

Even critics note the UN is "not just the chamber behind me. It is tens of thousands of women and men around the world. Feeding the hungry. Vaccinating children. Promoting development."

It also functions as "Protecting civilians in peacekeeping operations. Mediating conflicts. Supporting refugees and migrants. Advancing human rights. Standing, delivering, extending a lifeline of hope." and remains "a major actor for the weak and forgotten; and it is sometimes the only actor assisting in certain countries — an institution that is ready and able to go where others are not."

In practice in 2024:

Another analysis summarized: regional organizations play supporting roles, but "none can replace the United Nations in legitimacy, scale, or authority" and it "remains relevant, particularly in humanitarian coordination, international law, refugee protection, and global health. However, its effectiveness in preventing or stopping conflicts between major powers is widely debated."

This reflects the UN's paradox: "unmatched global legitimacy coupled with structural constraints that limit effectiveness."

Public opinion in the United States reflects this ambivalence: "Americans don't believe the United Nations is doing a good job, but mostly continue to support its mission and existence".

Why its relevance is questioned

1. Security Council paralysis and the veto

The most frequent criticism is that the Security Council does not reflect today's world.

Secretary-General António Guterres on 17 September called Security Council reform an "'absolute priority'" and warned that the conduct of permanent members has fostered a global "'environment of impunity' that emboldens nations to defy international law".

In practice:

This has led to warnings that the "UN's slide into near-irrelevance continues unabated."

2. Inability to end major wars

As world leaders gathered for the 80th anniversary General Assembly in September 2025:

Observers noted the annual gathering is "less important for what the UN does (which is little in the realm of preventing or ending wars) than for what it provides, namely a venue for all sorts of bilateral and multilateral meetings among the high-level visitors. Think of it as Davos for diplomats."

Richard Gowan, UN director for the International Crisis Group, described the United Nations as "an organization that is sort of in free fall."

Many resolutions "are non-binding, even as they may impact international norms... Yet, these symbolic gestures often fail to translate into practical and actionable outcomes."

This echoes President Donald Trump's criticism: "It has such tremendous, tremendous potential, but it's not even coming close to living up to that potential. For the most part, at least for now, all they seem to do is write a really strongly worded letter and then never follow that letter up."

3. Budget, bureaucracy and geopolitical headwinds

Can it stay relevant? Reform efforts

The UN is trying to adapt.

Analysts note that while reforming the veto is unlikely - since it would require unanimous P5 support - streamlining what the UN does best — its humanitarian organizations — which "sit one step removed from the veto politics of the P5 and can deliver tangible gains to places in need, even when high diplomacy stalls" may be the most constructive path.

Bottom line

The UN is still relevant as:

It is widely seen as ineffective and in need of reform when it comes to preventing or ending wars involving a P5 member or its allies, enforcing international law, and reflecting 21st century power realities.

As one expert concluded: "The case for multilateralism and global governance is stronger than ever. But, for better or worse, it will have to take place largely outside the UN" unless the organization reforms — a view many still debate but that captures the current tension between the UN's indispensability and its limitations.
