United Nations — The U.S. and other global powers are grappling with how to respond to the recent discovery of uranium particles in Iran that were enriched up to almost 84% — very close to the purity required to make nuclear weapons. A team of inspectors from the United Nations' International Atomic Energy Agency (IAEA) found the tiny amount of high enriched uranium at one of Iran's nuclear facilities during a scheduled visit and included it in their report.

 

The IAEA report, obtained by CBS News, noted the discovery of some particles enriched to 83.7% at the Fordow nuclear plant, but did not conclude that Iran was stockpiling uranium enriched above 60%, which the world already knew Iran was doing.

From the Iranian point of view, possessing nuclear weapons has a big benefit: warding off major attacks on its territory. I'm sure it hasn't been lost on them that Ukraine, by surrendering all its nuclear weapons, left itself vulnerable to a Russian invasion.
