The United Nations as a global actor: VCE Politics
“The role of the United Nations as an institution of global governance in responding to global issues and crises, and the limits on its effectiveness”
The United Nations was founded in 1945 to maintain peace, develop friendly relations, achieve cooperation on shared problems and harmonise state action, and it now has 193 members. Its six principal organs are the General Assembly (universal but non-binding), the Security Council (binding but limited by the five permanent members' vetoes), the Secretariat, the International Court of Justice, the Economic and Social Council and the suspended Trusteeship Council. It is highly effective in humanitarian relief, peacekeeping, development goals and norm-setting, but the veto paralyses collective security when a great power is involved, as Russia's veto over Ukraine shows. Its power is borrowed from members, so effectiveness is uneven.

What this dot point is asking
The United Nations is the leading example of an institution of global governance in the study design, so it appears in many answers on how global actors respond to a global issue or crisis, not just as one item in a list of actors. You need to know its founding purposes, its principal organs and what each does, and you need to judge how effective it is at maintaining peace, advancing development and protecting human rights. Exam questions ask you to evaluate the effectiveness of the United Nations, so you need to weigh its achievements against its structural limits and support both with current examples.
The answer
What the United Nations is for
The United Nations was created in 1945 after the Second World War to prevent another global catastrophe. Its Charter sets out four broad purposes: to maintain international peace and security, to develop friendly relations between states, to achieve cooperation on economic, social and humanitarian problems, and to be a centre for harmonising the actions of states. It now has 193 member states, making it the closest thing to a universal forum in global politics. Its founding principles include the sovereign equality of members and the prohibition on the use of force except in self-defence or when authorised by the Security Council.
The principal organs
The Charter establishes six principal organs.
- The General Assembly. All members sit and vote equally on a one-state-one-vote basis. It debates any issue, sets the budget and passes resolutions, but its resolutions are recommendations rather than binding law.
- The Security Council. The body responsible for peace and security, able to impose sanctions and authorise force. It has five permanent members (China, France, Russia, the United Kingdom and the United States) who each hold a veto, plus ten elected members.
- The Secretariat. The administrative arm, led by the Secretary-General, who manages the organisation and can use diplomacy and standing to influence events.
- The International Court of Justice. The principal judicial organ, which settles legal disputes between states and gives advisory opinions.
- The Economic and Social Council. Coordinates economic, social and development work.
- The Trusteeship Council. Created to oversee decolonisation, now suspended having completed its task.
Around these organs sit specialised agencies such as the World Health Organization, the refugee agency UNHCR and the children's fund UNICEF, which deliver much of the practical work.
Evaluating effectiveness
The record is genuinely mixed.
- Where it works. The United Nations has delivered large-scale humanitarian relief, run peacekeeping missions that stabilised post-conflict states, set global development goals and built the human rights framework. The General Assembly can confer legitimacy by condemning aggression with large majorities, as it did over Ukraine.
- Where it stalls. The Security Council veto is the central weakness. When a permanent member is a party to a crisis, it can block any binding action against itself. Russia's veto over Ukraine and deadlock over Syria show how the body designed to keep the peace can be paralysed by the very great powers it was meant to discipline.
- Structural limits. The organisation depends on members for funding, troops and enforcement. It has no army of its own, so its power is borrowed and conditional.
A defensible judgement is that the United Nations is highly effective in humanitarian and norm-setting roles and weakest where great-power rivalry is sharpest, namely collective security.
The five permanent members of the Security Council (China, France, Russia, the United Kingdom and the United States) each hold a veto. A single veto blocks any binding resolution, which is why the Council is often paralysed when a permanent member is involved in a crisis, as Russia is over Ukraine.
Examples in context
Example 1. Legitimacy without enforcement. After Russia's 2022 invasion of Ukraine, the General Assembly condemned the aggression by overwhelming majorities, conferring strong international legitimacy on Ukraine's position. Yet because Russia could veto the Security Council, this condemnation could not be turned into binding action, illustrating the gap between the United Nations as a moral forum and as an enforcer.
Example 2. Practical work through agencies. Agencies such as UNHCR and the World Food Programme deliver food, shelter and protection to tens of millions of displaced people each year. This shows the United Nations is often most effective not through the Security Council but through its specialised agencies doing concrete humanitarian work.
Students often write as though the United Nations can order states around and enforce its will. It cannot. It has no army, depends on members for funding and troops, and respects sovereign equality. Marks for evaluation come from recognising that its authority is borrowed and conditional, not assuming it commands.

- Cue. General Assembly, Security Council, Secretariat, International Court of Justice, Economic and Social Council, Trusteeship Council.
Q2. Explain why the Security Council is often unable to act. [6 marks]
- Cue. The veto held by the five permanent members; when a permanent member is involved, binding action is blocked, as over Ukraine and Syria.
Q3. Evaluate the effectiveness of the United Nations as a global actor. [10 marks]
- Cue. Weigh humanitarian relief, peacekeeping, development and norm-setting against the veto and dependence on members, and reach a defensible judgement.

2022 VCAA-style (previous design)5 marksDiscuss the effectiveness of the United Nations (UN) in achieving two of its aims.Show worked answer →
Five marks for a "discuss", so pick two clear aims and weigh successes against limits for each, with current examples.
Aim 1 - maintaining international peace and security. The UN runs peacekeeping missions and can authorise sanctions or force through the Security Council, and it conferred strong legitimacy on Ukraine when the General Assembly condemned Russia's 2022 invasion by large majorities. But the veto held by the five permanent members paralyses collective security when a great power is involved: Russia vetoed binding action over Ukraine, and the Council deadlocked over Syria. So the UN is partly effective but structurally limited where rivalry is sharpest.
Aim 2 - cooperation on economic, social and humanitarian problems. Through agencies such as UNHCR, the World Food Programme and the World Health Organization the UN delivers relief to tens of millions and sets shared goals (the Sustainable Development Goals). This is where it is most effective, though it depends on member funding and cannot compel states.
A strong conclusion judges the UN as highly effective in humanitarian and norm-setting roles and weakest in enforcement, because its power is borrowed from members. Markers reward two named aims, evidence on each side, and an overall judgement.
2021 VCAA-style (previous design)7 marksFrom the list below, select another global crisis that you have studied this year [climate change, armed conflict, terrorism, economic instability]. Analyse the effectiveness of one intergovernmental organisation (IGO) in responding to this global crisis.Show worked answer →
Seven marks: name a crisis, name an IGO, and analyse how effective its response has been with evidence on both sides. The United Nations is the strongest IGO to choose.
Take armed conflict and the United Nations. Analyse its tools: Security Council authorisation of peacekeeping and sanctions, UN-brokered ceasefires and humanitarian access, and General Assembly resolutions that build legitimacy.
Where effective: UN peacekeepers have stabilised post-conflict states and protected civilians, and UN agencies deliver large-scale relief to people displaced by war.
Where limited: the veto lets a permanent member block binding action when it is party to the conflict, as Russia did over Ukraine, leaving the UN able to condemn but not enforce. The organisation has no standing army and relies on members for troops and funding.
The analytical judgement that earns the top band: the UN is effective at relief and legitimacy but weak at coercive resolution precisely where great-power interests collide. Tie every point to the chosen crisis.
