The United Nations Security Council (UNSC) is the most important international institution.
- The UNSC has five permanent members: The United States, Russia, China, United Kingdom, and France. These are the winners of World War II.
- Ten other members rotate on two-year terms.
- All important United Nations legislation must go through the Security Council.
- Passing a resolution requires 9 of 15 votes. Each permanent member can unilaterally veto any resolution, however. This reflects their military strength.
