Legal regime of nuclear non-proliferation imposes upon the IAEA the obligation to ensure the full protection of confidential nuclear information offered by member states. Implementation of mutual obligations requires each party to adhere to its obligations, but the IAEA seemingly is willing to receive more information and broadly monitor Iranian nuclear activities, instead of giving due consideration to the latter's right to have its sensitive information secured. Therefore, recent years have seen daunting challenges, with Iran's concerns have not been sufficiently fulfilled. Violation of the obligation to ensure the full protection of confidential information together with prejudicing the credibility of the non-proliferation verification regime raises the IAEA's responsibility towards Iran and gives it the right to take self-help measures.
