United Nations Security Council
If a country has behaved in a way seen as bad, the member countries of UNSC can make a ruling, known as a United Nations Security Council Resolution. All five of the permanent member countries must either agree to this ruling or at least not vote against it; if any of them do, it is said to have been "vetoed" and does not come into effect. This Resolution may call for UN members to take certain actions to punish the country, called "sanctions".
