Answer :
The United Nations (UN) was established in 1945, principally to prevent military conflicts among nations and to maintain international peace and security. One core component of the UN's structure dedicated to this purpose is the United Nations Security Council, which includes fifteen member states, with five of them being permanent members: United States, Russia, China, France, and the United Kingdom. These permanent members wield significant power, including the right to veto resolutions, which can stop major UN decisions.
The UN Security Council's composition and functions have been established to address threats to global peace and facilitate diplomatic solutions. With ten non-permanent members elected for two-year terms and five permanent members, the Council has the power to authorize sanctions, peacekeeping operations, and even military force in cases of aggression. The high threshold for resolutions—a nine-out-of-fifteen vote majority—and the veto power of permanent members are significant political tools in the UN's efforts to fulfill its mission.
