Article 51 of the United Nations Charter is about the right to self-defense. This right was less controversial before the 9/11 attacks.But during the last twenty years, following two major conflicts in the Middle East and the Security Council's reaction to it, this right and how to invoke it, became the subject of controversy again. In this article, according to the claim of revision of the security council in the concept of self defense and issuing resolutions on behalf of this organization, the behavior of the council has been investigated and analyzed in this regard. In general, despite the issuance of the resolutions of 1368 and 1373, but the lack of repetition of this issue in several resolutions issued by the council in the following years, shows the lack of fundamental change in the behavior of the council towards the concept of self defense. Even the issuance of Resolution 2249, which some consider as a basis for resorting to self defense against ISIS, lacks the necessary justification. it was not issued based on the seventh chapter of the charter. On the other hand, the council has increasingly strengthened the role of the structures under its supervision in its procedure to deal with terrorism. It has also strengthened the council's literature on terrorism as a threat to international peace and security, which is considered its main area of responsibility.Therefore, the Council's action regarding the permission to resort to self defense against terrorism should be considered an exception.
