Is the United Nations still relevant?

Is the UN still relevant? I'll make the case for and against — gathering the latest evidence on its global impact and its biggest challenges.

Yes - but it is at arguably its most vulnerable and contested moment in 80 years.

The short answer most analysts give is: the United Nations remains indispensable but ineffective in its core security role, and highly relevant in its humanitarian, development and normative roles - but its ability to perform any of those roles is now under severe pressure.

1. Why it is still considered relevant

A. Its foundational purpose still holds
One common argument is that 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. The UN came into existence 80 years ago, as its charter came into force... founded as an effort to avert another world war in the aftermath of Germany's surrender.

Arguably, it has succeeded so far, and on its 80th anniversary the Charter was described as:

> The Charter of the United Nations has been the foundation of the post-World War international order... It has saved humanity from the scourge of a new world war, a nuclear holocaust, prevented or settled numerous conflicts, advanced human rights, facilitated decolonization

Secretary-General António Guterres has argued that while the Charter's Principles are as relevant as ever, the role of the United Nations becomes even more relevant in a context of structural constraints and growing vulnerability.

The UN today remains one of the world's oldest and largest multilateral institution today, 193 member states, the only universal forum where all states can meet.

B. What only the UN system does at scale

No other organization replicates its operational footprint:

As one assessment for 2026 put it:

> The UN remains indispensable, and the expectations placed on it have expanded. Yet its authority and effectiveness are increasingly contested, while political support and resources have narrowed

2. Why many say it is becoming irrelevant

A. Security Council paralysis

The most cited reason is the veto. In the 2020s, the Council has faced renewed paralysis, with repeated vetoes by Russia over the war in Ukraine and by the United States over the war in Gaza, prompting fresh calls for structural reform.

At a debate on working methods, delegates said:

> ...some permanent members' abuse of the veto had serious consequences for the organ's credibility... the Council's paralysis amounted to death and destruction in Gaza and Ukraine

Some warned that ignoring widespread negative perceptions of the veto — and the Council's resulting inaction — risks rendering the UN irrelevant in the public eye.

Recent analysis notes the U.S.'s repeated use of the veto during the war in Gaza has depleted goodwill, while Russia's invasion of Ukraine has similarly left the Council unable to act.

B. Financial and political crisis

The UN enters 2026 at a moment when global disorder and institutional constraints converge, placing unprecedented pressure on how multilateral governance is exercised.

2025 was described as:

> Last year was among the darkest in the history of the United Nations. Gripped by a budgetary crisis and unable to respond to catastrophic wars in Sudan, Ukraine and Gaza, the U.N. spent much of 2025 focused on internal reform

The funding crisis follows the partial non-payment of assessed contributions ... operating at a level well below the approved 2025-26 budget. The crisis, which UN peacekeeping chief Jean-Pierre Lacroix described as "more daunting than ever," left the UN facing the possibility of ending 2025 with a cash deficit.

A major driver is the United States, which helped found the United Nations after World War... but issued Executive Order 14199 on February 4, 2025 Withdrawing the United States From and Ending Funding to Certain United Nations Organizations. By late 2025, the United States has almost stopped paying membership fees, and has now owed more than 3 billion US dollars in dues.

In response, Guterres proposed a 2026 regular budget of $3.715 billion slightly below the 2025 approved budget, later revised down to US$3,238 million, a reduction of US$577 million compared to 2025 with an 18.8% staffing cut, and launched the UN80 Initiative to modernize the organization.

Some observers argue that to stay relevant in 2026 the U.N. must become less inward-looking and more strategically relevant and re-focus on preventing great-power confrontation from escalating, rather than just internal budget discipline.

Other critiques include:

3. The verdict: Relevant, but not as designed in 1945

> This is not 1945

The consensus among most scholars and diplomats is:

The UN is not relevant as a collective security enforcer when the P5 are divided — it cannot stop a war waged by a permanent member or its ally. In that sense it is functioning as its founders intended — as a “Concert of Great Powers” rather than a world parliament — and when that concert fails, the Security Council fails.

The UN is highly relevant as a service provider, convener, and legitimizer — feeding hungry people, vaccinating children, sheltering refugees, monitoring elections, setting climate and development goals, and providing the only universal legal framework for state sovereignty and human rights. No other body can deploy 90,000 peacekeepers or coordinate aid in 70+ crises at once.

Whether it stays relevant depends on two 2026 tests often cited:

As one Small Island State delegate asked in the General Assembly: “Why has the UN Security Council failed humanity,” — a question that captures both the frustration and the expectation that the world still looks to the UN first when it fails.

Without the UN, there is no alternative universal forum. With it in its current form, expectations far exceed what the structure allows it to deliver.
