Some argue that deterrence is the key to ensuring not only that Iran abides by the deal, but also to preventing them from developing nuclear weapons.  Former Assistant Secretary of Non-Proliferation Robert Einhorn, a supporter of the deal, wrote that it would be preferable to have permanent or longer-term restrictions on Iran`s enrichment program, but that it is possible to prevent a nuclearly armed Iran “provided that the United States and important partners maintain a strong and credible deterrence against a future Iranian decision to go with the bomb.”  According to Michael Eisenstadt, director of the Security and Defense Studies Program at the Washington Institute for Near East Policy, “Iran`s deterrence from the development or acquisition of nuclear weapons will remain in the coming years the core of the imperative that will drive U.S. policy.”  The reinstatement of sanctions amounts to a violation by the United States of the original agreement, while Iran was deemed compliant, according to international nuclear inspectors. On August 25, 2015, a group of 53 Christian religious of various faiths sent a message to Congress asking them to support the Agreement.  Christian leaders wrote: “This is a time to think of the wisdom of Jesus who, in the Sermon on the Mount, proclaimed, `Blessed are the peacemakers, for they will be called children of God` (Matthew 5:9). There is no doubt that with this agreement we are all better off than without.  The letter was coordinated by a group of Quakers, the Committee of Friends of National Legislation.

Foreign Department spokesman John Kirby replied, “There is no secret agreement between Iran and the IAEA of which the P5+1 has not been informed in detail” and stated, “Such technical agreements with the IAEA are a matter of standard practice, whether they are disclosed publicly or to other states, but our experts are familiar and familiar with the content. that we would like to discuss with Congress in a secret setting.  The Center for Arms Control and Non-Proliferation wrote, “The agreement establishes procedural information on how the IAEA will conduct its investigation into Iran`s nuclear history, including mentioning the names of informants interviewed. The publication of this information would endanger these informants and the information they hold.  Mark Hibbs, of the Nuclear Policy Program at carnegie Endowment for International Peace, and Thomas Shea, a former IAEA security officer and former head of defense non-proliferation programs at pacific Northwest National Laboratory, wrote that the allegations of a “secret agreement” made by opponents of the agreement were a “fabricated controversy.”  Hibbs and Shea wrote: “The IAEA has entered into a safeguards agreement with 180 countries . . .
