The foreign minister said the Biden administration has a "limited window of opportunity" to re-enter the 2015 nuclear agreement from which the former US administration withdrew unilaterally in May 2018.

Asked just how swiftly Iran could scale back its uranium enrichment program to comply with the nuclear deal if the US lifts sanctions, Zarif said, "8,000 pounds of enriched uranium can go back to the previous amount in less than a day."
"If we wanted to build a nuclear weapon we could have done it some time ago.
"But we decided that nuclear weapons are not, would not augment our security and are in contradiction to our ideological views. And that is why we never pursued nuclear weapons," Zarif noted.
