Expert: I'd be surprised if we don't get an Iran deal

(CNN) - As fellow American officials met with allied and Iranian counterparts in Geneva, Switzerland, U.S. Secretary of State John Kerry said that all sides are closer than they've been in a long time on a nuclear deal.

"We have the best chance we've had in a decade, we believe, to halt progress and roll back Iran's program," Kerry said from Washington.

Experts seem to agree.

"I would be surprised, I think, if we don't get a deal," said Robin Wright, Middle East analyst with the Woodrow Wilson Center.

"Iran needs a deal like never before. The value of its currency is gone, has been cut by over half. Its oil exports have also been cut by more than half," said Wright. "They have an enormous incentive."

While important negotiations are happening in Geneva, several more happening in other regions will also play a role in any deal that is brokered.

"There is a debate inside Iran in which the moderates led by President Rouhani and the chief negotiator who is in Geneva are dealing with the hardliners, including the Iranian Revolutionary Guard," said David Sanger, reporter with The New York Times.

"Then there's another debate going on and another deal will have to be brokered right back here, between the White House and those in Congress who want to add on additional sanctions at a time that President Obama says, 'Hold up, let's let this process work out,'" said Sanger.
