The Iran nuclear deal will clear a crucial milestone on December 15, when the International Atomic Energy Agency submits a report on the extent of Iran's
previous nuclear-weaponization activities.
The completion of that investigation into the possible military dimensions (PMDs) of Iran's nuclear program is one of the major prerequisites for the full implementation of the Joint Comprehensive Plan of Action (JCPOA), the landmark nuclear deal that Iran and a US-led group of six countries signed in July.
In theory, the JCPOA won't be implemented unless Iran complies with a separate "roadmap" agreement with the IAEA. That agreement, which was signed the same day as the JCPOA, lays out the parameters of the agency's weaponization investigation. The JCPOA isn't supposed to go into effect unless the sides "fully implement" that roadmap agreement.
But "full implementation" doesn't really have a fixed meaning within the JCPOA, an agreement that is voluntary and non-binding. And according to an Associated Press analysis out Monday, the IAEA's investigation is likely going to have inconclusive results.
As the AP notes, the head of the IAEA has "been careful to diminish expectations, describing his upcoming report last week as 'not black and white.'" And according to the AP, Iranian officials have spoken about the IAEA probe using similar language, "suggesting they already know that the agency's conclusions won't be damning."
Iran has already threatened that it simply won't comply with the JCPOA if it's dissatisfied with the IAEA's report. That might be more than just an empty ultimatum, since according to the AP the announcement is consistent with what Iranian diplomats are saying behind closed doors as well.
"Two Western diplomats familiar with the issue say those same threats have been made in negotiations with IAEA officials," the AP reported.
The weaponization report is considered crucial to the successful implementation of the nuclear deal, as it will be used to formulate an inspection baseline for Iran's nuclear program. There is extensive evidence that Iran had a nuclear weapons program until as late as 2003. The IAEA needs to be able to identify key personnel, facilities, supply chains, and past activities to establish exactly how far along Iran's weaponization activities really are and to recognize whether those activities have been restarted.
But as the AP's analysis suggests, the roadmap is also contentious — and perhaps even inconvenient, given its potential to interrupt the smooth implementation of a deal that Iran and the US-led group spent nearly two years negotiating. There are already signs that the US wants to get past the investigation as smoothly as possible — even if the IAEA's "roadmap" doesn't result in Iran's full disclosure of its past weaponization work.
