As Iran prepares to break through limits set by its 2015 nuclear deal with world powers, each step narrows the time its leaders would need to have enough highly enriched uranium for an atomic bomb — if they chose to build one. By Thursday, June 27, 2019, Iran says it will have over 300 kilograms of low-enriched uranium in its possession, which would mean it had broken out of the atomic accord.
