What the secret agreement between Iran and the UN says

Here are some questions and answers about the document, and what it means for the larger deal between Iran, the United States and five other world powers to limit Iran's nuclear activities in exchange for easing sanctions against Iran.

WHAT HAVE IRAN AND THE IAEA AGREED?

According to a draft document viewed by AP, Iran has agreed to cooperate with the U.N. in answering longstanding allegations about possible past work to develop nuclear weapons at its Parchin plant — but only with the Iranians conducting the inspections themselves. Iran would collect its own environmental samples on the site and carry out other work usually done by IAEA experts. The IAEA will be able to review the Iranians' work after the fact. The deal on Parchin was between the IAEA and Iran. The Obama Administration was not a direct party to the agreement, but apparently was awere of it.A

WHAT DO OPPONENTS OF THE DEAL SAY? 

Opponents of the broader deal are seizing an opportunity to say the entire exercise of negotiating with Iran is flawed, that it relies too much on trust of the Iranian government.

WHAT DOES THE OBAMA ADMINISTRATION SAY?

The Obama administration and other supporters say the wider agreement say it is focused on the future, with ample inspections, and that the side accord between Iran and the IAEA is focused on Iran's activities in the past and therefore is not central to the overall deal.

HOW UNUSUAL IS THE AGREEMENT ON PARCHIN?

Any IAEA inspection of a country suspected of nuclear irregularities is usually carried out by agency experts. They may take swipes of residue on equipment, sample the air or take soil samples in attempts to look for signs of clandestine work on atomic arms or other potentially dangerous unreported activity.

The document on Parchin, however, will let the Iranians themselves look for signs of the very activity they deny — past work on nuclear weapons. It says "Iran will provide" the agency with environmental samples. It restricts the number of samples at the suspect site to seven and to an unspecified number "outside of the Parchin complex" at a site that still needs to be decided.

The U.N. agency will take possession of the samples for testing, as usual. Iran will also provide photos and video of locations to be inspected. But the document suggests that areas of sensitive military activity remain out of bounds. The draft says the IAEA will "ensure the technical authenticity of the activities" carried out by the Iranians — but it does not say how.

In contrast, the main nuclear deal with Iran gives IAEA experts greatly expanded authority compared to what it has now to monitor Iranian nuclear activities as it works to ensure that Tehran is hewing to its commitments; reducing the scope and output of programs that Iran says it needs to generate energy but which can also be turned to making the fissile core of atomic weapons.WHY IS THE PARCHIN AGREEMENT IMPORTANT?

Any indication that the IAEA is diverging from established inspection rules could weaken the agency, the world's nuclear watchdog with 164 members, and feed suspicions that it is ready to overly compromise in hopes of winding up a probe that has essentially been stalemated for more than a decade.

Politically, the arrangement has been grist for American opponents of the broader separate agreement to limit Iran's future nuclear programs, signed by the Obama administration, Iran and five world powers in July. Critics have complained that the wider deal is built on trust of the Iranians, while the administration has insisted it depends on reliable inspections.

The separate agreement on past nuclear activities does not affect the broader deal signed in July. And it doesn't appear yet that the revelation will change any votes in Congress for or against a resolution of disapproval, which President Barack Obama is expected to veto if it passes.
