Why can it be said that the Security Council does not operate a democracy?

The Security Council of the United Nations does not operate as a democracy because its decision-making power is concentrated in the hands of five permanent members—China, France, Russia, the United Kingdom, and the United States—who possess veto power over substantive resolutions. This structure allows these countries to block any action, regardless of majority support from other members, undermining principles of equal representation and majority rule. Additionally, the Council's membership and procedures do not reflect a one-person, one-vote system, further distancing it from democratic ideals.
