Is the United Nations still relevant?

Is the UN still relevant? I'll gather current assessments of its effectiveness and challenges to give you a balanced view.

The United Nations is still relevant, but its relevance is increasingly contested and uneven - strong in humanitarian, development and as a diplomatic forum, weak in its core mandate of maintaining international peace and security - a tension sharpened as it marks its 80th anniversary.

> As the United Nations marks its 80th anniversary, the question of the body’s relevance looms large. Undercut by financial shortfalls, US retrenchment, and growing geopolitical divides, can the UN remain a vital stage for global diplomacy

Why it is still seen as relevant

1. Indispensable forum and legitimacy:
Almost all of its more than 190 member states still send heads of state to the General Assembly high-level week, which is described as a clear indicator that the United Nations is widely viewed to be politically relevant and an important platform for shaping international discourse.

Even critics note that since its inception, the United Nations has played a pivotal role in shaping international relations and addressing global challenges.

That perception is reflected in public opinion. In the Spring 2025 Pew Global Attitudes Survey a majority of South Africans (57%) have a favorable opinion of the UN, which generally receives positive marks across the 25 countries surveyed.

More broadly in 2026, a median of 55% have a favorable opinion of the UN, according to a spring Pew Research Center survey. A median of 37% have an unfavorable opinion. In 2025 the median was 61% favorable to 32% unfavorable. That perception makes the United Nations a still-useful venue for international contestation — and a tool for nations seeking international power and prestige.

The UN maintains that with China stepping back from engagement, others will step in, and Beijing's influence within the UN has steadily grown as China has taken over leadership positions throughout the UN agency system.

2. Humanitarian and development work:
The UN is often judged not by Security Council votes but by its agencies.

Together with partners, the UN coordinated a $50 billion appeal for the humanitarian needs of 198 million people. “In 2024, the United Nations helped to mobilize $25 billion of the $50 billion funding target, enabling life-saving humanitarian assistance to reach 116 million people in urgent need across 77 countries and territories.”

It also allocates emergency funds like $100 million from its Central Emergency Response Fund to underfunded aid operations.

3. Peacekeeping and global norms:
The United Nations maintains a substantial peacekeeping apparatus comprising military and civilian personnel deployed across multiple regions to monitor ceasefires, separate combatants, and create conditions for political dialogue. As of recent years, the UN has maintained approximately 13 peacekeeping operations across Africa, Asia, Europe, and the Middle East, involving nearly 100,000 military personnel and civilian staff

UN peacekeeping chief Jean-Pierre Lacroix said he wanted UN peacekeeping to “continue to be an indispensable multilateral tool in the peace and security toolbox"

Other historic normative achievements cited include the Universal Declaration of Human Rights (1948) and the 2030 Agenda for Sustainable Development.

Why its relevance is questioned

1. Security Council paralysis and veto:
Much of the criticism directed at the United Nations eventually arrives at the Security Council.

The veto power of the P5 frequently hindering effective action.

As it stands, a veto from any of the permanent members can halt any possible action the Council may take. One country's objection, rather than the opinions of a majority of countries, may cripple any possible UN armed or diplomatic response to a crisis.

Examples frequently cited: since 1982, the US has vetoed 32 Security Council resolutions critical of Israel, and Russia has vetoed attempts to impose sanctions on Syria and to condemn Russia's own annexation of Crimea.

Due to its restrictive administrative structure, the permanent members of the Security Council themselves have sometimes prevented the UN from fully carrying out its first two mandates. Some have questioned whether the UN might be relevant in the 21st century.

This legitimacy crisis was described in 2025 as:

> The most fundamental challenge to the relevance of the United Nations is intimately linked to perceptions of its legitimacy. For many, this has been irretrievably compromised

That includes Russia's violation of Ukraine's sovereignty, China refusing to condemn it, and the United States seen to have hit a high-water mark in hypocrisy over Gaza. Other critics note there are essentially no consequences for violating a Security Council resolution.

2. Financial and structural crisis:
The International Crisis Group describes the UN at 80 as:

> The United Nations is an institution that is having to take a crash diet. The world organisation is struggling with a severe financial crisis as the Trump administration has withheld almost all US funding for its activities

That has threatened to create a spiral downward as other states, especially China, delay their own financial support, reducing the ability to tackle climate change, global health, humanitarian disasters and development goals which is shrinking rapidly. The US withdrawing from the Paris Agreement and the World Health Organization has disrupted progress on two of the greatest challenges.

Bureaucratic dimension has long been a cause for frustration, and the organization has faced persistent criticism from governments, scholars, and publics over its effectiveness, consistency, and ability to prevent wars.

3. Declining favorability in some countries:
While net-positive globally, favorable views are down in 10 countries over the past few years, including a 17 point drop in Nigeria (80% in 2025 to 63% in 2026) and 16 points in the Philippines, and to the lowest level in South Korea since 2007.

Verdict

Most analysts argue the UN remains relevant but not in the way its 1945 founders envisioned:

The current debate is therefore less about abolishing the UN and more about reform - expanding the Security Council, limiting veto use on genocide, ensuring predictable funding, and adapting peace operations to climate, technology and urban conflict - to make it "fit for purpose" for the next 80 years.
