The primary function of the United Nations Security Council is to maintain international peace and security. It oversees the implementation of international laws, mediates conflicts, and can authorize military actions or sanctions against aggressor states. Comprising 15 members, including five permanent members with veto power, the Council is responsible for addressing threats to global stability. Its effectiveness, however, can be challenged by political divisions among nations, highlighting the complexities of diplomacy and the ongoing strive for peace in a multipolar world.
