The UNSC, one of the six principal organs of the UN, is responsible for maintaining international peace and security. The Security Council has the authority to call for use of force to achieve the same. The decisions taken by the UNSC in general are binding in nature on all member nations. The other powers of the UNSC include the authority to start peacekeeping operations and place international sanctions. Approvals to the changes to the UN Charter are also through the UNSC.
