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 are elected by the General Assembly for two-year terms.
UN 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 UN 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 has gone to war or invaded a country without Security Council approval.
