Now the onus is on Iran to begin implementing the deal, as noted by AL Monitor:
The next JCPOA benchmark is “adoption day,” Oct.18, when Iran must begin to make changes in its nuclear infrastructure in compliance with the JCPOA, working with the International Atomic Energy Agency. US officials this week summarized what needs to happen before sanctions are lifted, including “taking out thousands of centrifuges and putting them into IAEA-monitored storage [at the Natanz enrichment facility) … taking out a very large amount of infrastructure, specifically some of the pipework and electrical infrastructure that allows for the enrichment process to work; …
& etc – an impressive list. They finish with,
Only when Iran takes these and other steps, including a report from the IAEA on the past military dimensions of Iran’s nuclear program, does the process shift to the next benchmark, “implementation day,” when certain sanctions are lifted. Implementation day is expected to take place in spring 2016, but could be longer, or even never. It all depends on Iran.
The Tehran Times reports,
It is thought unlikely that international sanctions will be lifted before next year. The timing depends on when Iran meets its commitments and the IAEA confirms Iran has resolved all outstanding issues with the agency.
And The Iran Project suggests the deal isn’t quite done yet:
Speaking with reporters on Saturday [presumably September 19 – Hue], the Supreme Leader’s top aide, Ali Akbar Velayati, was cautious about the confirmation of the deal by Iranian officials: “I should say that the nuclear negotiations have not ended yet since the legal authorities should still make a decision about it, and it is still soon to make any comments before the legal authorities declare their decision.”
Velayati noted the ongoing review by Parliament: “This will continue until we come up with definite results and we hope that the Islamic Republic of Iran’s interests and expediencies will be met in this trend.”
