Last week Mossad Chief Meir Dagan, Israel’s top spy, said he expected the unrest in Iran to drop off in a matter of days rather than escalate into a full-fledged revolt. He also estimated that the Iranians would not obtain a nuclear weapon before 2014. “If the reformist candidate Mousavi had won, Israel would have had a more serious problem, because it would need to explain to the world the danger of the Iranian threat,” he told a panel of Israeli lawmakers last week.
