The Security Council, the United Nations’ principal crisis-management body, meets regularly to assess threats such as international security, natural disasters, and terrorism.
Its 5 permanent members—the United States, China, France, Russia, and the United Kingdom—each have veto power.
The veto gives them each the power to block any substantive resolution or decision that threatens their national interests, security, or foreign policy objectives. In response to these threats, the Security Council can impose sanctions, establish peacekeeping missions, and, in certain instances, authorize the use of force.
Permanent members of the council have exercised their veto power to varying degrees. Russia has been the most frequent user of the veto—counting the years when the Soviet Union held its seat—blocking 162 resolutions since the Security Council’s founding, as of August 2026. The U.S. has used the veto 95 times, often to protect Israel from Security Council decisions.
China has vetoed fewer resolutions, but has done so more frequently in recent years; Russia joined China in more than three-quarters of those votes. By contrast, neither France nor the UK has exercised its veto power since 1989, and each has advocated for other permanent members to use it less.
Members’ competing interests have often stymied the Security Council’s ability to respond to major conflicts and crises, including Russia’s 2022 invasion of Ukraine. Russia’s vetoes of Security Council action on Ukraine have spurred calls to kick Russia out as a permanent member of the global body.
The UN human rights chief from 2014 to 2018, Zeid Ra’ad al-Hussein, repeatedly criticized the outsize power of the veto-wielding member states, warning that without institutional change the United Nations could collapse.
Critics also argue the threat of a veto alone can prevent action, allowing permanent members to shape Security Council outcomes even when no vetoes are cast.
