The United Nations considers NATO to be a "regional arrangement" under UN Article 52, which allows it to deal with matters relating to the maintenance of international peace and security as are appropriate for regional action provided that such arrangements or agencies and their activities are consistent with the Purposes and Principles of the United Nations. However, the UN policy on military intervention by regional arrangements in UN Article 53 states the Security Council can, where appropriate, "utilize such regional arrangements or agencies for enforcement action under its authority. However, no enforcement action shall be taken under regional arrangements or by regional agencies without the authorization of the Security Council."
