President Trump wants a deal to constrain Iran’s nuclear program, and he sees an opportunity while the country is struggling at home with growing dissent following nationwide protests last month. Iran meanwhile has maintained it wants to continue to enrich uranium even as its program sits in ruins, following Trump ordering an attack in June on three of the Islamic Republic's nuclear sites, part of a bruising 12-day war last year.
If an American attack happens, Iran has said all U.S. military bases in the Mideast would be considered legitimate targets, putting at risk tens of thousands of American service members. Iran has also threatened to attack Israel, meaning a regional war again could erupt across the Middle East.
In this round of negotiations after the June war, Trump has pushed to halt Iran's enrichment of uranium entirely, as well as address Tehran's ballistic missile program and its support of regional militant forces. Iran has maintained the talks must remain focused only on nuclear issues.
U.S. Secretary of State Marco Rubio told reporters Wednesday that Iran is “always trying to rebuild elements” of its nuclear program. He said that Tehran is not enriching uranium right now, “but they’re trying to get to the point where they ultimately can.”
