A House Divided Against Itself: Can the United Nations Still Deliver for the World?

The United Nations was founded to stop wars. Eight decades later, it has become remarkably efficient at documenting them. As world leaders gather in New York for the 2026 United Nations General Assembly under the theme, "Restoring trust, managing transformation: a United Nations that delivers for all," Gaza remains devastated, Ukraine grinds through another year of war, Sudan descends deeper into catastrophe, and great-power rivalry has returned as the defining force of international politics. The irony is difficult to ignore. The United Nations is no longer failing because it lacks ideals; it is failing because the world's major powers no longer wish to be constrained by the very rules they once created.

The UN's founding promise in 1945 was ambitious: to prevent another global war, uphold international law and replace power politics with collective security. It helped dismantle colonialism, built the modern human rights architecture and coordinated peacekeeping and humanitarian relief across continents. Yet today's reality tells a harsher story. From Iraq in 2003 to Russia's invasion of Ukraine and the repeated paralysis over Gaza, the organisation has proved unable to restrain powerful states. It has become increasingly effective at recording violations of international law, but far less capable of preventing them.

The deeper problem is not the Secretariat or its Secretary-General. The UN merely reflects the political will of its members. Institutions rarely become stronger than the states that control them. The Security Council is paralysed not because diplomacy has failed procedurally, but because powerful nations increasingly treat international law as optional whenever it conflicts with strategic interests. Washington condemns territorial aggression in Ukraine while defending Israel against many UN resolutions. Moscow invokes sovereignty while violating it. Beijing champions multilateralism even as it rejects unfavourable international rulings in the South China Sea. Rules applied selectively cease to be rules; they become instruments of power.

Nowhere is this contradiction more visible than in the Security Council. Its permanent membership and veto power continue to reflect the geopolitical realities of 1945 rather than those of 2026. Africa has no permanent seat despite representing more than a quarter of UN member states. India, the world's most populous nation, along with Brazil, remains excluded, while Latin America lacks permanent representation altogether. Small island states that contribute least to climate change face its gravest consequences yet possess limited influence over global decisions. The UN increasingly asks the Global South to trust institutions in which it has little voice. Reform has been debated for decades, but the tragedy is that meaningful reform requires the consent of precisely those powers whose privileges it would diminish.

The consequences extend beyond the Security Council. The world's most consequential strategic decisions increasingly emerge outside the UN through minilateral groupings such as the Quad, AUKUS, BRICS, the G20 and other regional coalitions. Great powers increasingly prefer flexible partnerships based on shared interests over universal institutions bound by consensus. The UN remains the venue for speeches; geopolitical bargains are struck elsewhere.

Even in areas where the organisation performs indispensable work, it faces growing constraints. Agencies such as UNHCR, the World Food Programme and UNICEF continue to save millions of lives through refugee protection, food assistance and vaccination campaigns. Yet liquidity crises, delayed assessed contributions and growing dependence on voluntary donor funding have forced budget cuts and staff reductions. An organisation dependent upon the generosity of the very governments it may one day have to criticise inevitably sacrifices a measure of independence.

The same contradiction shapes emerging global challenges. Climate change, pandemics, cyber conflict and artificial intelligence cannot be managed by any nation acting alone. The UN remains the only universal forum capable of convening nearly every country, drafting norms and facilitating dialogue. Yet it possesses almost no authority to enforce collective action. It can negotiate principles. It cannot compel compliance. Its legitimacy therefore rests increasingly on persuasion rather than power.

Declaring the United Nations obsolete would nevertheless be a mistake. No alternative institution can coordinate humanitarian relief, negotiate global treaties or provide smaller states with an equal diplomatic platform. The real alternative is not a stronger international order but a fragmented world governed by competing spheres of influence, transactional alliances and unconstrained power politics.

The crisis of the United Nations is therefore not merely institutional. It is civilisational. It reflects a world where sovereignty increasingly outweighs solidarity, power routinely overwhelms principle and national interest consistently defeats collective responsibility. The organisation has become less the architect of world order than its mirror.

As another General Assembly concludes with carefully crafted speeches and familiar promises of reform, the challenge is no longer identifying what must change but finding governments willing to change it. The greatest danger is not that the United Nations disappears. It is that the world quietly adjusts to its irrelevance. History will judge the UN not by the resolutions it adopted or the summits it convened, but by whether it found the courage, and whether its members found the will, to adapt before irrelevance became irreversible.
