In the same letter, Obama explained the possible unilateral and multilateral non-military reactions that should be used in the event of Iran`s violation of the agreement, but the president said, ”Ultimately, it is important to maintain the flexibility to decide what reactive measures we and our allies deem appropriate for any non-compliance.”  Flexibility meant that Obama had previously opposed the establishment of ”sanctions for minor violations of the agreement.”  Under the JCPOA, Iran must submit a full report on its nuclear history before sanctions can be received.  The IAEA has confidential technical agreements with many countries as part of the standard operating procedure.   ”Republican legislators call these agreements ”secret secondary restrictions” and assert that the JCPOA depends on a series of agreements that no one in government has really seen.”  Senator Tom Cotton of Arkansas, a Republican opponent of the agreement, said Kerry had ”behaved like Pontius Pilate” and ”washed his hands, kicked the IAEA, because he knew that Congress would not receive this information if no one came out to find it.”  On July 30, Texas Republican Senator Ted Cruz introduced a resolution requesting a delay in the audit period and argued that ”the 60-day period for reviewing such an agreement in the Senate can only be considered beginning when the majority leader certifies that all documents that must be submitted under such legislation according to the definition of ”agreement.” , including any ancillary agreement with Iran and the guidelines for Iran issued by the U.S. government, were forwarded to the majority leader.  On 5 August, IAEA Director General Yukiya Amano met with members of the Senate Foreign Relations Committee in a briefing on two IAEA documents: an agreement on inspection protocols with Iran and an agreement with Iran on the disclosure of its previous nuclear activities (known as potential military dimensions).   After this briefing with Amano, Corker told reporters: ”The majority of the members here left the group with many more questions than before the meeting” and ”We cannot even make him confirm that we will have physical access inside Parchin.” Cardin told reporters, ”I thought it was useful today, but it wasn`t a substitute for seeing the document.”  The agreement followed the Joint Action Plan (JPA), an interim agreement between the P5-1 powers and Iran, reached in Geneva on 24 November 2013.
