Is the United Nations still relevant?

The UN's relevance is hotly debated — I'll survey current evidence of its impact and its critics.

The United Nations remains relevant, but its relevance is uneven and increasingly contested - it is indispensable in some areas, paralyzed in others.

Why It Is Still Considered Relevant

1. Near-universal membership and legitimacy: As it marks its 80th anniversary, the question of relevance looms large, but the fact that its more than 190 member states, with only a few exceptions, are sending representatives from across the world to New York City for the 80th sessionis seen as a clear indicator that the United Nations is widely viewed to be politically relevant and an important platform for shaping international discourse and influencing public opinion. An assessment at the 81st General Assembly was that the world still needs the United Nations — and that its universality must not become hostage to the convenience of the powerful.

Polling suggests this view is shared globally. Though the United Nations may not be a priority for Americans, the United Nations' image around the world remains favorable. Most publics in the 25-nation 2025 Pew Global Attitudes Survey hold net-positive views, with favorable views rising in countries such as South Africa, Nigeria and Germany.

More generally, it is still described as one of the world's most important — and surprisingly impactful — institutions.

2. Humanitarian, health and development work:

Yes, the United Nations remains relevant, particularly in humanitarian coordination, international law, refugee protection, and global health.

The UN system touches lives daily, including work many may not realize:

In that sense, as one analysis put it: So, is the United Nations still relevant today? Spoiler: Yes.

3. Forum for diplomacy: At its core, the UN is a space where countries — big and small — can talk and hash things out without needing to send troops, and in a world that feels more divided by the day, the United Nations is one of the few institutions trying to pull humanity in the same direction — toward peace, progress, and shared responsibility.

Why Its Relevance Is Questioned

1. Security Council Paralysis and the Veto:

The most frequent criticism is aimed at the UN Security Council (UNSC), established to maintain global peace and security, which has faced increasing criticism for its inability to address contemporary crises effectively. The veto power held by the five permanent members (P5) has often led to inaction during critical conflicts.

The United Nations Security Council has repeatedly demonstrated inadequacies in preventing mass atrocities and maintaining international peace, primarily due to the veto power wielded by its five permanent members (P5), which enables any one to block substantive action aligned with their national interests.

International institutions, foremost among them the United Nations, established to resolve conflicts, prevent wars, and ensure collective security, are increasingly marginalized or paralyzed due to geopolitical tensions and institutional deadlock.

On Gaza and Ukraine, a veto holder is a party or a patron, and the Council is paralysed as a result, and the Council's inability to adopt unanimous decisions on Syria, Ukraine and Palestine is seen as evidence of institutional deadlock.

Structurally, the UN has grown from 50 members 75 years ago to 193 members, but its basic structure gives little real power to the main body, the General Assembly, and the most to the World War II victors‐ Britain, China, France, Russia and the United States ‐ with each wielding a veto on the 15‐seat Security Council as permanent members.

Related to legitimacy, one expert argued: 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, pointing to Russia blatantly violating the sovereignty of Ukraine, China refusing to condemn it, and the United States providing seemingly unconditional support for Israel's actions in Gaza.

2. Financial Crisis and Power Shifts:

Undercut by financial shortfalls, US retrenchment, and growing geopolitical divides, can the UN remain a vital stage for global diplomacy or will competing powers shape a world order that sidelines it.

The UN's ability to deliver material solutions has been radically diminished by the United States' decision to delay critical budgetary support and put caps on its contributions to UN peacekeeping.

In 2025, President Donald Trump issued an executive order mandating the withdrawal of the United States from several United Nations agencies, including the Human Rights Council (UNHRC) and UNRWA, and later withdrew from UNESCO, while undertaking a comprehensive review of American financial contributions.

By early 2026, Secretary-General António Guterres warned the organization could exhaust cash for core operations by mid-year, with outstanding dues hitting a record $1.568 billion by the end of 2025, with collections covering just 76.7% of assessments.

With the United States stepping back, China is looking to step up and has steadily grown its influence within the UN agency system.

3. Implementation Gap:

On climate and development, annual gatherings have lost steam as an important driver of progress. New NDC pledges were due in February 2025 but only 36 states had announced new ones, illustrating the gap between UN agreements and country implementation.

Conclusion: Relevant but in Need of Reform

Analysts generally agree the UN is not heading for disappearance, but for transformation. The UN is Turning 80. Is It Still Relevant? — the answer from most experts is: yes for humanitarian action, peacekeeping, international law, and as a universal forum where all voices can be heard, but no for effective collective security without reform of the veto, funding model, and representation.

Common reform proposals include expanding permanent membership of the Security Council, limiting use of the veto in cases of mass atrocities, and securing more predictable financing. Without such changes, the UN risks remaining, as critics argue, indispensable for keeping people alive but ineffective at stopping the wars that put them in danger.
