The use of veto power in the United Nations Organization (UNO) is only exercised by the Security Council. The Security Council is one of the main bodies of the UNO and is responsible for maintaining international peace and security. It consists of 15 members, including 5 permanent members (China, France, Russia, the United Kingdom, and the United States) who have the power to veto any substantive resolution. This means that if any one of the five permanent members votes against a resolution, it cannot be passed, even if all the other members vote in favor of it. The use of veto power has been a controversial issue, as it can often lead to a deadlock in decision-making and prevent action on important issues.
