Is the United Nations still relevant?

Whether the United Nations (UN) is still relevant is one of the most critical debates in modern international relations. As the organization marks eight decades since its founding in 1945, it is facing unprecedented geopolitical polarization, financial crises, and structural paralysis. At the same time, many diplomats and experts argue that the global system would collapse into chaos without it.

To understand its current standing, it is helpful to look at both sides of the debate.

The Case Against: Why the UN is Losing Relevance

Critics argue that the UN is increasingly ineffective, outdated, and unable to meet the security challenges of the 21st century.

•Security Council Paralysis: The UN's primary body for maintaining global peace—the Security Council—is frequently deadlocked. Because the five permanent members (the U.S., Russia, China, the UK, and France) hold veto power, any major power involved in a conflict can block collective action. This has paralyzed the UN’s ability to halt devastating conflicts, such as the war in Ukraine, the Israel-Gaza-Iran crisis, and the civil war in Sudan.

•Outdated Power Structure: The UN's design reflects the geopolitical realities of the immediate post-World War II era. It does not adequately represent the rise of the Global South, nor does it give permanent representation to emerging global powers like India, Brazil, or African nations. Despite years of talk about reforming the Security Council, member states remain deadlocked on how to do it.

•Financial Instability and Funding Cuts: The UN is enduring severe financial strain. Key donors, most notably the United States, have historically frozen or significantly cut funding to various UN agencies. This has forced sweeping staff reductions and severely weakened the UN’s operational capacity precisely when humanitarian needs are at record highs.

•Failure of Core Goals (SDGs): The UN's ambitious Sustainable Development Goals (SDGs) for 2030 are severely lagging. Reports show that the vast majority of targets—ranging from ending poverty to combating climate change—are off track, raising questions about the UN's ability to drive tangible global progress.

The Case For: Why the UN Remains Indispensable

Supporters argue that while the UN is flawed, its absence would leave a dangerous vacuum that no other organization could fill.

•An Irreplaceable Humanitarian Lifeline: Even when the political wings of the UN fail, its humanitarian agencies—such as the World Food Programme (WFP), UNICEF, the World Health Organization (WHO), and the High Commissioner for Refugees (UNHCR)—remain the primary safety net for tens of millions of people in active war zones and disaster areas. No other global network has the scale, logistics, or legal mandate to deliver life-saving aid to the world's most vulnerable populations.

•The Only Universal Forum: The UN General Assembly remains the only venue on Earth where all 193 sovereign nations, regardless of size or wealth, have an equal voice and a seat at the table. It is the premier stage for diplomatic communication, allowing adversarial nations a channel to speak and prevent misunderstandings from escalating into direct world wars.

•Managing Transnational Threats: Modern crises are global and cannot be solved by individual nations. The UN is the only body capable of orchestrating multilateral treaties on issues like climate change (the Paris Agreement), global health (the WHO Pandemic Agreement), and digital and AI safety (addressed in the UN’s Pact for the Future).

•Conflict Mitigation and Peacekeeping: While the UN struggles to stop wars between major powers, its peacekeeping forces and special envoys work quietly to stabilize dozens of fragile areas worldwide, preventing local skirmishes from spiraling into wider regional wars.

The UN at a Crossroads

The UN is undergoing a critical period of transition. Under the UN80 Initiative, the organization is actively trying to restructure, cut costs, and streamline its sprawling agencies. Furthermore, with Secretary-General António Guterres's term concluding, member states are searching for a successor to lead the organization, with many hoping a new leader can break the current diplomatic malaise.

Ultimately, the UN's relevance depends on how one defines its purpose. If the UN is judged on its ability to enforce world peace and eliminate geopolitical rivalry, it is failing. However, if it is judged as a necessary buffer—a flawed but vital shock absorber designed to keep the world talking and to keep the most vulnerable alive—then the United Nations remains as relevant as ever. As the saying often attributed to diplomat Dag Hammarskjöld goes: "The UN was not created to take mankind to heaven, but to save humanity from hell."
