Three former high-ranking U.S. foreign policy advisers agree that if Iran does not halt its suspected nuclear weapons program by the end of 2013, the United States or Israel will act militarily.

Dennis Ross, until a year ago President Obama’s top Iran policy adviser, and Elliott Abrams, a former deputy national security adviser to President George W. Bush, spoke at an event in their honor held Dec. 6 in New York by the Washington Institute for Near East Policy, the Times of Israel reported.

Asked by Washington Institute director Robert Satloff if they believed either America or Israel would use their military against Iran’s nuclear program before the end of 2013 if it is not stopped by that time, Ross and Abrams said yes.

Ross and James Jeffrey, a former deputy national security adviser and the current ambassador to Iraq, predicted a U.S. strike in that case.

“I think there’s the stomach in this administration, and this president, that if diplomacy fails,” force will be used, Ross said.

Jeffrey agreed, saying, “I think if we don’t get a negotiated settlement, and these guys are actually on the threshold as Obama said during the campaign, then the president is going to take military action.” He predicted the decision would come halfway through 2013.
