CEVAP:

The only exception to the prohibition of the use of force is provided in Article 51 of the Charter. Article 51 establishes the right to self-defense of a state against armed attack. In case of armed attack, member states have the inherent right of individual or collective self-defense until the UNSC takes necessary measures. Members are obliged to immediately report their measures to the UNSC. However, such measures taken by member states under the right of self-defense cannot prevent the UNSC to take necessary measures for the maintenance of international peace and security. Given the history of international relations, it is not easy to establish which state has the right to self-defense and which state is the aggressor or victim in each and every case, because states have no consensus on the definition of aggression and attack (Mingst and Karns, 2012:24).
