Israel Exposes Iran's Nuclear Lies, and the Limits of U.S. Intelligence

Since Iran and six world powers reached an agreement to pause Iran's enrichment of uranium and allow weapons inspectors into declared facilities, Israel's prime minister has argued the deal would give Iran a glide path to a nuclear weapon. On Monday he announced that he had proof.

If the West can verify the new Israeli intelligence that Iran had preserved its design and research work into a nuclear weapon, that's a big deal — particularly now in light of the May 12 deadline that President Donald Trump has imposed on U.S. negotiations with Europe to come up with fixes to strengthen the nuclear bargain. The trove of data would be a blow not only to Iran's credibility but also to the reputation of American intelligence gathering.

As negotiations with Iran came to a close in summer 2015, John Kerry, then secretary of state, assured reporters that American intelligence agencies had "absolute knowledge" about Iran's past efforts to build a nuclear weapon.

It was a strange remark. As the intelligence assessments before the 2003 Iraq War showed, intelligence is never absolute. What's more, the International Atomic Energy Agency, or IAEA, still had its own outstanding questions for Iran. Indeed, that agency could not give Iran a clean bill of health on the possible military dimensions of its nuclear program nearly six months later.

Now Israeli Prime Minister Benjamin Netanyahu is claiming that his country's spies have purloined a warehouse full of videos, files, blueprints and designs for nuclear weapons compiled between 1999 and 2003. If verified, the new Israeli intelligence would show there were many details the U.S. didn't know back in 2015.
