7.1 International Organisations

No country can do it alone

Climate change, pandemics, terrorism, economic instability -- the biggest problems of our age have one thing in common: none of them respect national borders, and none can be solved by a single country acting alone. International organisations provide the frameworks and institutions through which states work together on these shared challenges.

The modern system of international organisations was built largely after the devastation of the Second World War. Leaders had seen how unchecked nationalism and the absence of effective cooperation helped produce two catastrophic global conflicts within a single generation. The answer was a new architecture of global governance, centred on the United Nations but reaching out to a wide range of specialised agencies and regional bodies. Today there are hundreds of international organisations shaping everything from trade policy to human rights standards. Understanding how they work -- and where they fall short -- is essential for making sense of contemporary international relations.

The United Nations and its powers

At the centre stands the United Nations (UN), founded in 1945 with 51 member states and now numbering 193. Its purposes, set out in the UN Charter, are to maintain international peace and security, develop friendly relations among nations, achieve cooperation on economic, social and humanitarian issues, and promote respect for human rights. The UN works through several key organs. The General Assembly gives every member one vote and discusses and recommends on global issues. The Security Council has 15 members -- including five permanent members with veto power: the USA, UK, France, Russia and China -- and bears responsibility for peace and security. The Secretariat is the administrative arm, led by the Secretary-General, and the International Court of Justice settles legal disputes between states. Crucially, the UN has no army of its own and no power to tax, so its effectiveness depends on the willingness of member states, especially the major powers, to cooperate.

One of the UN's most visible roles is peacekeeping. Since 1948 it has deployed over 70 peacekeeping operations, typically involving soldiers from many member states wearing the UN's distinctive blue helmets. Peacekeepers are not sent to fight wars; they monitor ceasefires, protect civilians and help build conditions for lasting peace, with successes in Mozambique, East Timor and Sierra Leone. But an honest account must include the failures too. In Rwanda in 1994, a small UN force was unable to prevent genocide, and in Srebrenica in 1995, Dutch peacekeepers failed to protect Bosnian Muslims from massacre. These tragedies raised hard questions about when and how the international community should intervene. The veto power of the five permanent members is itself a defining and controversial feature: it can block action even in the face of grave crises, which some defend as keeping the major powers engaged and others criticise as paralysing the Council -- a debate worth presenting fairly rather than taking a side on.

Beyond the UN: regional cooperation

Global bodies like the UN are not the whole story. Numerous regional organisations play significant roles in international relations, often allowing states with geographic proximity and shared interests to cooperate more effectively than they could through global institutions alone. The European Union (EU) is a supranational organisation of 27 European states with shared institutions, a common market and a single currency, the euro, used by most members; notably, it can pass laws that are binding on member states. NATO, the North Atlantic Treaty Organization, is a military alliance of 32 states in North America and Europe, built on the principle in Article 5 that an attack on one member is considered an attack on all. The African Union is a continental organisation of 55 African states promoting political and economic integration, and ASEAN, the Association of Southeast Asian Nations, is a regional bloc of 10 states focused on economic cooperation and stability.

These organisations illustrate two important distinctions in how states cooperate. The first is between intergovernmental and supranational bodies. Most international organisations are intergovernmental, meaning states cooperate while keeping their sovereignty -- the UN works this way. But some, like the EU, are supranational, meaning their authority can transcend and bind member states, who pool some of their sovereignty for shared benefit. This trade-off is central to debates about international cooperation: pooling sovereignty can enable more effective collective action but raises questions about democratic control. The second distinction concerns multilateralism -- cooperation among multiple states through institutions -- which is the basic principle underlying the whole system. The structure of these organisations affects how responsive they are, how power is checked, and how citizens experience the reach of international governance in their daily lives. The picture that emerges is of a layered system, with global, regional and specialised bodies each playing a part in helping sovereign states address problems too big for any one of them.

In short

Because the great challenges of our age cross borders, international organisations provide frameworks for states to cooperate, an architecture built largely after the Second World War. At its centre is the United Nations, with 193 members and key organs including the General Assembly and the Security Council, whose five permanent members hold a defining and controversial veto power. The UN has no army or taxing power, so it depends on member states' cooperation, and its peacekeeping record includes both successes and failures like Rwanda and Srebrenica. Regional organisations such as the EU, NATO, the African Union and ASEAN add further layers, illustrating the distinction between intergovernmental cooperation and the supranational pooling of sovereignty. The result is a layered system of multilateralism through which sovereign states tackle problems too big to face alone.
