The UN's Legitimacy Problem Is Increasingly About Who Gets to Exercise Power

Calls for African representation and Security Council reform reflect a widening gap between the UN's universal membership and the concentrated authority of its postwar institutions.

In this analysis
  1. Representation without authority has limits
  2. Incumbents possess the veto over reform
  3. Institutional legitimacy can erode before institutions change

The most persistent institutional argument at the 2026 General Assembly was not whether multilateral cooperation remains useful. It was whether a system designed around the distribution of power in 1945 can retain legitimacy when the distribution of population, economic weight and geopolitical influence has changed.

Demands for stronger African representation concentrate that tension in the Security Council, where permanent membership and veto power remain fixed.

Representation without authority has limits

The General Assembly gives states a voice, but the Security Council can authorise coercive measures and its permanent members can block action. Reform advocates are therefore asking for more than recognition. They are asking to redistribute decision rights.

Incumbents possess the veto over reform

The paradox is structural. The states whose privileged position is being challenged hold decisive power over changes to the Charter. That makes major reform difficult even when dissatisfaction is widespread.

Institutional legitimacy can erode before institutions change

The risk for the UN is not immediate collapse. It is gradual substitution, as governments route security, finance and diplomacy through smaller coalitions when universal institutions appear unable to act. The more that happens, the harder formal reform becomes to avoid.
