US Officials Say They Can Tell If Iran Is Cheating On Deal.

U.S intelligence officials say they are confident they can verify Iran's compliance with the recently completed nuclear deal, despite
a track record of misjudgments about weapons of mass destruction.

The main reason, according to a classified joint intelligence assessment presented to Congress, is that the deal requires Iran to provide an unprecedented volume of information about nearly every aspect of its existing nuclear program, which Iran insists is peaceful. That data will make checking on compliance easier, officials say, because it will shrink Iran's capacity to hide a covert weapons program.

"We will have far better insight (into) the industrial aspects of the Iranian nuclear program with this deal than what we have today," James Clapper, the director of national intelligence, told an audience last month at the Aspen Security Forum.

Outside experts don't dispute that. But they question — considering past analytical blind spots in the Middle East — whether American spying will really be able to catch every instance of Iranian cheating.

"The intelligence community can rarely guarantee, 'We're going find the secret site,' " said David Albright, a former weapons inspector who heads the Institute for Science and International Security. "They have found them before in Iran and that's good, but I think they are going to have to do more work and bolster their capabilities to find secret sites in Iran in an environment when Iran is taking counter measures against them."

Skeptics of the deal note that Iran is one of the world's hardest places in which to spy. Iran's intelligence agencies have penetrated CIA front companies, executed Western agents and captured a sophisticated U.S. drone.

The CIA has never had much success developing and keeping good intelligence sources in Iran, says Reuel Marc Gerecht, who worked as a CIA operations officer.

"The truth is that the CIA and the NSA are largely flying blind inside the Islamic Republic on the nuclear question," he wrote recently in the Weekly Standard.

Intelligence officials dispute that, saying their insights into Iran have improved considerably in recent years.

The CIA has "a reasonably high degree of confidence that we would be able to detect Iran if it were trying to deviate from the requirements that they've signed up to," David Cohen, the agency's deputy director, said at the Aspen Security Forum.

The United States, Russia, China, Britain, France and Germany reached the agreement with Iran on July 14 that would curtail its nuclear program in exchange for billions of dollars in relief from economic sanctions. The U.S. Congress is expected to vote next month on a resolution rejecting the agreement.

As part of the deal, Iran agreed to disclose nearly every element of its nuclear supply chain, including people, places, companies and infrastructure — "their entire nose-to-tail process for uranium production and processing," as one U.S. intelligence official put it, speaking on condition of anonymity because he was not authorized to speak publicly.

Those disclosures would vastly increase the chances that intelligence agencies would catch cheating, officials told Congress in classified briefings. That's because any illicit activity would have to take place outside the established network that had been laid bare to the West. Once the CIA knows all the places Iran has been importing and processing nuclear material, the country would have to develop new avenues to evade detection— a major undertaking. The briefings and the assessment were described by officials only on condition of anonymity.

The intelligence assessment presumes Iran will try to cheat, say officials familiar with it.

Even after 15 years, when restrictions on Iranian nuclear activities are lifted, Iran will still be prohibited from developing a nuclear weapon, and the U.S. will have more ability than it does now to detect any attempt, officials insist.

History provides reasons to be skeptical of U.S. ability to detect and gauge secret Iranian nuclear activity.

Foremost among them are the massive misjudgments in intelligence that helped justify the Iraq war. Nearly every U.S. spy agency concluded with some level of certainty that Saddam Hussein possessed active chemical and biological weapons programs. They were flat wrong.

Officials point out that the Iraq war debacle led to changes. On Iran, for example, agencies brought in "red teams," both from inside and outside to probe for weaknesses, question assumptions and ponder unlikely scenarios. The Iran analysis has withstood such probing, officials say.

Still, the American intelligence community has misjudged a number of major developments since then, including the Arab Spring, the Russian move into Ukraine and the swift military advance of the Islamic State.

The record on nuclear weapons development is particularly spotty. The CIA missed India's plan to test nuclear weapons in 1998, for example.
