Iran's nuclear program remains a top focus for inspectors from the International Atomic Energy Agency, particularly as any possible deal between Tehran and the United States over the program would likely rely on the agency long known as the United Nations' nuclear watchdog.
This week, Western nations will push for a measure at the IAEA's Board of Governors censuring Iran over its noncompliance with inspectors, pushing the matter before the U.N. Security Council. Barring any deal with Washington, Iran then could face what's known as “snapback” — the reimposition of all U.N. sanctions on it originally lifted by Tehran's 2015 nuclear deal with world powers, if one of its Western parties declares the Islamic Republic is out of compliance with it.
