Opinion | United Nations Day 2026 and Why Global Cooperation Matters

From preventing wars to tackling climate change and artificial intelligence, countries need to work together to address problems that affect the whole world.

Every year on October 24, the world observes United Nations Day. It marks the United Nations’ establishment in 1945, after the destruction caused by the Second World War. But is this day just an anniversary? Is it simply a date we remember every year? There is a much bigger reason behind it. The day reminds us that countries need each other to deal with problems that no nation can solve alone.

Today, we live in a connected world where events in one country can affect people thousands of kilometres away. Climate change, wars, disease, cybercrime and the rapid growth of artificial intelligence have made cooperation more important than ever. These issues affect our daily lives, even when they happen far away from us. Understanding the role of the United Nations is therefore important for everyone, not just diplomats and political leaders.

Born from Global Conflict

To know about the formation of the UN, we have to consider the first part of the twentieth century. The Second World War had brought death and destruction to many, and it was clear to countries that they had to do something new to avoid a third global war.

The failure of the League of Nations, formed after the First World War, to prevent another world war was one of the reasons for forming a more powerful organization which would promote talks and keep peace in the world.

On June 26, 1945, representatives of 50 countries signed the United Nations Charter in San Francisco. The Charter came into effect on October 24 that year. Poland signed the Charter later and became the 51st founding member of the UN.

The aim of forming the United Nations was quite obvious: nations needed a common ground where they would be able to talk about the existing disagreements and find ways of resolving them peacefully. The UN did not manage to stop each and every conflict, but it provided the means to deal with international issues through talks and cooperation.

More than eight decades later, the world faces different challenges, yet the need for countries to work together remains the same.

How the United Nations Works

The United Nations is not a world government. It is an international organisation where independent countries come together to discuss common problems and cooperate on global issues.

It has six principal organs. The General Assembly provides a platform for all member states to discuss international matters. The Security Council deals with international peace and security. The Economic and Social Council works on economic, social and development issues. The International Court of Justice deals with legal disputes between states within its jurisdiction. The Secretariat manages the organisation’s daily work under the Secretary-General. The Trusteeship Council, meanwhile, suspended its operations in 1994 after completing its original purpose.

The activities undertaken by the UN touch on peace and security, human rights and sustainable development. They are interrelated. When there is a conflict in a certain nation, for example, the schools are closed, the hospitals struggle, and the people have lost their homes and source of income. While peace has to be restored, other needs arise.

Sustainable Development Goals and the 2030 Agenda

UN member states formulated 17 Sustainable Development Goals (SDGs) back in 2015. The SDGs include goals related to poverty, hunger, education, health care, equality between genders, water, energy, climate change, and others.

What this all means is that there will be better lives and a saved planet. Every country has its own challenges and priorities. For some, the challenges may include poverty and unemployment, whereas others might find themselves dealing with issues of water scarcity, environmental pollution, or lack of access to education and healthcare services. The SDGs have made it easier for countries to move in the same direction, hence collaboration and exchange of experience in order to solve these problems.

It is easier said than done, because now governments need to follow through on their promises, fund and assess the effectiveness of their policies. With 2030 fast approaching, there should be some serious movement towards this objective.

Navigating a Changing World

When the United Nations was established in 1945, much of the world’s attention was focused on rebuilding countries and preventing another major war. Today, many challenges are more complex and can cross national borders within seconds.

Climate change affects countries regardless of where emissions originate. Infectious diseases can spread through international travel, while cyberattacks can target systems across continents. False information can reach millions of people through social media in a short time.

The advent of artificial intelligence has opened up many possibilities in education, healthcare, and research. However, there are fears over privacy, human rights, misinformation and abuse of the technology. Nations have to ensure that they utilize these opportunities and, at the same time, protect themselves from any potential danger.

In September 2024, UN member states adopted the Pact for the Future at the Summit of the Future. It focuses on strengthening international cooperation, improving global governance, addressing emerging technologies and giving greater attention to young people and future generations. The agreement also includes commitments on sustainable development, peace and security.

Why Global Cooperation Matters

Take, for example, climate change, epidemics and cybersecurity issues. They have no boundaries, meaning that even an institutionally sound and technologically advanced country can suffer consequences of events happening elsewhere.

Through cooperation, nations can share knowledge in science, exchange information, as well as coordinate action in cases of emergencies. Through this, nations can also be able to utilize their resources better and benefit from each other’s experience.

This can apply to humanitarian situations as well. Conflicts may lead to population displacement and disruption of education, among other vital services. International aid can offer necessities including food and medical care, among others.

Cooperation does not imply that every nation has to agree on every matter. There is diversity in terms of interests, political ideologies and priorities, among other things. What matters most is agreeing on common ground and ensuring that differences do not impede progress on mutual problems.

Challenges and the Need for Reform

It is no small task to bring together 193 member states of the UN and reach a consensus on anything. Every state has unique interests and economic and security concerns, which makes decision-making within international organizations quite difficult.

Take the Security Council as an example. There are five permanent members with the right to veto substantive decisions made in this body: the USA, Great Britain, France, Russia and China. When there is disagreement between these parties, the work of the Security Council slows down even in cases of significant international events.

There are still questions regarding representation, funding and accountability in international organizations. Today, many states think international organizations should represent the world as it is now and give more influence to developing nations when it comes to decision-making.

The UN80 initiative, initiated in March 2025, is one attempt to improve the performance of the organization. This process involves evaluation of the mandate, improvement of cooperation and finding effective means to utilize current resources.

Looking Towards the Future

As the United Nations marks its 81st anniversary in 2026, an important question remains: can countries overcome their differences to address the problems they share? A simple solution does not exist. Cooperation necessitates dialogue, trust, and a political will to cooperate. Cooperation also necessitates an understanding by governments that some issues can only be addressed in collaboration and not individually.

The United Nations has had some criticism and disappointments in its history, and its shortcomings must be acknowledged openly. Nonetheless, it remains a forum for diplomacy, humanitarian aid, international law, and development cooperation.

The theme for United Nations Day still holds; problems affecting humanity as a whole require cooperation on an international scale. Since the end of the Second World War, which saw the emergence of the UN, the world has changed dramatically, with new issues arising such as climate change, artificial intelligence, and digital security.
