Overview: The Security Council has 15 members.
There are five permanent members: the United States, the Russian Federation, France, China, and the United Kingdom.
Ten temporary members elected by the General Assembly for two-year terms.

U.N. Security Council Voting: To be approved, a Council resolution must have nine "YES" votes out of 15 and no "NO" votes from any of the five permanent members.
Each Council member has one vote.
A "NO" vote from one of the five permanent members kills the resolution.
There is no such thing as a "VETO" vote in formal U.N. rules, though a "NO" vote from a permanent member has the effect of vetoing a resolution.
If a member "ABSTAINS" from voting, it does not count as either a "YES" or "NO" vote.
Members raise their hands to vote, and sit at a horseshoe-shaped table.
Each of the five Permanent Members have gone to war or invaded a country without Security Council approval.
Security Council Vetoes: The United States has used its veto 83 times. The United States did not use its veto until 1970, but has used it frequently since, over issues concerning the Middle East.
