'Engagement Is Losing Credibility': Iranian Foreign Minister

Iran would commit to permanent nuclear inspections in exchange for a permanent lifting of U.S. sanctions, Iran's Foreign Minister Mohammad Javad Zarif told NPR's Steve Inskeep on Thursday.

"We can do it right now in order to make sure that people can be at ease that Iran will never develop nuclear weapons ... in exchange for a permanent lifting of sanctions ratified by U.S. Congress, exactly as envisaged for 2023. We can do it now," Zarif said. He was in the U.S. to attend a United Nations meeting.
