But with optimism for the talks low, some experts say the world powers, and principally the US, must come up with a much bigger game-changer than a modest reduction of sanctions if they are to move Iran – and perhaps to avoid another Middle East war as early as this summer.
“You could have a deal on the nuclear issue within weeks if the US accepted a certain level of safeguarded enrichment,” says Flynt Leverett, a former director for Middle East affairs in the Bush administration National Security Council (NSC) and professor of international affairs at Pennsylvania State University. But that “would basically mean accepting the Islamic republic [of Iran]” as a legitimate power, he adds – something Mr. Leverett advocates.
Leverett, who with his wife, Georgetown University professor Hillary Mann Leverett, recently published “Going to Tehran,” says the US president ultimately will have to pull off something that “parallels the Nixon-Kissinger opening to China” in 1972 and “accept Iran and [it] having an independent foreign policy.”
President Obama has vowed to stop Iran from building a nuclear weapon, while ally Israel – which Mr. Obama will visit in March – insists that Iran on its current trajectory may well have assembled the stockpile of enriched uranium and other elements permitting a “break-out” to a rapid assembly of a nuclear bomb by this summer.
