Iran and six world powers can reach a comprehensive nuclear deal by agreeing on Iran’s practical needs for enrichment, which are limited in the near term; as well as on technical modifications that could be made to the Arak reactor and turning the Fordo enrichment site into a research and development facility, former US nuclear negotiator Robert Einhorn writes in a paper to be released by the Brookings Institution Monday.
“I think of the big issues, Arak is the easiest,” Einhorn told Al-Monitor in an interview last week. "Fordo is hard. But the hardest single issue is enrichment capacity."
