Is the United Nations still relevant?

The relevance of the United Nations is one of the most fiercely debated questions in modern global politics. At recent UN General Assembly summits, world leaders from all regions have increasingly questioned whether the 80-year-old institution is still fit for purpose.

The consensus among foreign policy experts, diplomats, and leaders is dual: the UN is deeply paralyzed at its highest political levels, yet it remains absolutely indispensable on the ground.

An overview of both sides of the debate reveals why the UN is struggling, alongside the reasons it remains vital to the global order.

The Case Against: Why the UN Appears Increasingly Irrelevant

Critics, and even many of the UN's own member states, argue that the organization is failing in its primary post-WWII mandate: to prevent wars and maintain international peace and security.

•Security Council Paralysis and Gridlock: The UN Security Council (UNSC) is the only body with the authority to issue binding resolutions, deploy peacekeepers, or authorize military action. However, because the five permanent members (the U.S., Russia, China, France, and the UK) hold veto power, the council is regularly deadlocked. Wars in Ukraine, Gaza, and Sudan have highlighted a system unable to act because great powers routinely block resolutions that conflict with their geopolitical interests.

•An Outdated 1945 Power Structure: The UN’s architecture reflects the geopolitical realities of the end of World War II, not the multipolar world of today. Entire regions and rising powers—most notably Africa, Latin America, and India—have no permanent representation on the Security Council, despite representing billions of people. This has triggered a profound crisis of legitimacy, with leaders arguing that the UN has lost global trust.

•Sidelined by Regional and Bilateral Diplomacy: Increasingly, nations are bypassing the UN to resolve major crises. Peace talks, economic coordination, and security agreements are being negotiated through regional blocs (such as the G20, the African Union, or minilateral partnerships) or independent bilateral initiatives, leaving the UN to act merely as a bystander.

•Financial and Budgetary Crises: The UN has been gripped by severe financial strain, driven in part by member states failing to pay their dues. Budget cuts, particularly from the United States, have forced the organization to trim its bureaucracy, leading to internal operational struggles.

The Case For: Why the UN Remains Indispensable

Despite these severe shortcomings, supporters and realist diplomats argue that if the UN were disbanded today, the world would immediately have to reinvent it.

•The Unreplaceable Humanitarian Lifeline: While the UN’s political arms struggle, its operational agencies do the heavy lifting of global survival. Agencies like the World Food Programme (WFP), the High Commissioner for Refugees (UNHCR), and the Office for the Coordination of Humanitarian Affairs (OCHA) are the premier actors delivering aid, medicine, and food to millions in war-torn regions like Sudan and Yemen.

•Active Peacekeeping in Fragile Zones: Despite dramatic cuts in funding, the UN continues to field thousands of peacekeepers across active missions globally. These forces, though imperfect, prevent local conflicts from escalating into regional wars in some of the world's most dangerous environments.

•The Sole Forum for the "Global Commons": Issues that transcend national borders—such as climate change, pandemics, and the regulation of artificial intelligence—cannot be solved by any single country or regional bloc. The UN Framework Convention on Climate Change (UNFCCC) remains the only mechanism capable of bringing 193 nations together to set binding climate targets and coordinate action.

•A "Safety Valve" for Great Powers: Czech President Petr Pavel famously remarked that "diplomacy matters most not between friends, but between adversaries." Even in times of heightened geopolitical tension, the UN provides a physical space where rivals (such as the U.S., China, and Russia) are forced to sit in the same room, maintain communication channels, and outline red lines, preventing miscalculations that could lead to global conflict.

The Verdict: "Reform or Lose Trust"

The debate over the UN is no longer about whether the institution is flawed, but rather how it must adapt to survive.

As UN Secretary-General António Guterres has noted, the world has changed, but the UN has not kept pace. For the UN to remain relevant, it must undergo structural reform—particularly by expanding the Security Council to reflect 21st-century demographics and power balances.

Without these changes, the UN risks becoming a grand but toothless talking shop, even as its humanitarian arms continue to serve as the world's ultimate safety net.
