Can you tell me what part of the UN charter it contravened. I know. Do you?
The international legal rules governing the use of force take as their starting point Article 2(4) of the U.N. Charter, which prohibits any nation from using force against another. The charter allows for only two exceptions to this rule: when force is required in self-defense (Article 51) or when the Security Council authorizes the use of force to protect international peace and security (Chapter VII).
Article 2(4): All members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.
Article 51: Nothing in the present Charter shall impair the inherent right of individual or collective self-defense if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security. Measures taken by Members in the exercise of this right of self-defense shall be immediately reported to the Security Council and shall not in any way affect the authority and responsibility of the Security Council under the present Charter to take at any time such action as it deems necessary in order to maintain or restore international peace and security.
