State Dept. says it could 'revisit' key part of Iran nuke deal

The State Department on Tuesday refused to say that it would block sanctions relief for Iran if that country fails to give international inspectors full details about its prior efforts to build nuclear weapons.

Instead, a State Department spokesman indicated that the P5+1 countries that negotiated the deal might "revisit" the question of what to do in the face of a sub-par report on Iran's past activities.

The International Atomic Energy Agency is expected to release a report today explaining what it learned about the "possible military dimensions" of Iran's past nuclear work. Just last week, IAEA chief Yukiua Amano said that so far, the agency is "not in a position" to verify that "all nuclear material in Iran is in peaceful activities."

And as of this week, there were already reports implying that the IAEA will not be able to verify all past aspects of Iran's nuclear work. That finding would likely rekindle Republican opposition to the deal, and prompt them to reject the idea of lifting sanctions against Iran as now proposed in the agreement.
