Security Council Veto
The power of any of the five permanent members of the UN Security Council to unilaterally block the adoption of a substantive resolution.
Updated April 23, 2026
How It Works
The Security Council veto power is a unique authority granted to the five permanent members (P5) of the United Nations Security Council: the United States, the United Kingdom, France, Russia, and China. When a substantive resolution—one that addresses significant issues like peace and security—is put to a vote, any one of these P5 members can exercise their veto to block its adoption, regardless of the majority support it may have. This means that even if 14 out of 15 members vote in favor, a single veto from a permanent member stops the resolution from passing.
Why It Matters
The veto power was designed to ensure that major powers remain engaged in the UN system by protecting their vital interests. It serves as a check to prevent the Security Council from taking actions that could be perceived as hostile or unfair by any of these key nations. However, this power also means that the Security Council can be deadlocked, preventing timely action in crises when one permanent member opposes intervention. This has profound implications for international peacekeeping, conflict resolution, and global diplomacy.
Security Council Veto vs General Assembly Decisions
Unlike the Security Council, the UN General Assembly does not have veto powers; decisions there are usually made by majority vote. The veto is exclusive to the Security Council's permanent members and only applies to substantive matters. Procedural votes in the Security Council cannot be vetoed, allowing the council to at least manage its agenda even when divisions exist.
Real-World Examples
One notable instance of the veto in action was during the Syrian conflict, where Russia and China have repeatedly vetoed resolutions aimed at condemning the Syrian government or authorizing intervention. Another example is the United States' frequent use of its veto in matters relating to Israel. These vetoes have often sparked debate about the effectiveness and fairness of the Security Council's decision-making process.
Common Misconceptions
A common misconception is that the veto power can be used on any UN matter. In reality, it only applies to substantive Security Council resolutions, not all UN decisions. Additionally, some believe that vetoes are used frequently and indiscriminately, but in practice, vetoes tend to be reserved for issues of critical national interest to the P5 members.
Example
In 2011, Russia and China used their veto power to block a Security Council resolution authorizing military intervention in Syria, illustrating the impact of the veto on international conflict resolution.
