A senior White House official said that one of the US president's top priorities in his second term in office is to resolve the nuclear issue with Iran.

White House Deputy National Security Advisor Ben Rhodes told progressive activists earlier this year that striking a nuclear deal with Iran would probably be the biggest foreign policy achievement of President Barack Obama in his second term, the Washington Free Beacon reported on Friday.

“Bottom line is, this is the best opportunity we’ve had to resolve the Iranian issue diplomatically, certainly since President Obama came to office, and probably since the beginning of the Iraq war,” Rhodes said in audio obtained by the American news website. “So no small opportunity, it’s a big deal. This is probably the biggest thing President Obama will do in his second term on foreign policy. This is healthcare for us, just to put it in context.”

The remarks show the importance of a rapprochement between the United States and Iran to Obama, who has publicly stated that the likelihood of a nuclear deal between six world powers and Iran is no greater than 50-50.

Rhodes also said that the Obama administration does not want Congress to securitize any final agreement.

“We’re already kind of thinking through, how do we structure a deal so we don’t necessarily require legislative action right away,” he said. “And there are ways to do that.”

Iran and the P5+1 group -- Russia, China, France, Britain, the US and Germany – are negotiating to narrow their differences over the Islamic Republic’s nuclear energy program ahead of a November 24 deadline.
