Outgoing Mossad Director Meir Dagan has revised his earlier prognosis that Iran would not have nuclear weapons before 2015 because of technical obstacles. In his last briefing to the Knesset Foreign Affairs and the Security Committee, Monday, Jan. 17, Dagan said, “The Iranian nuclear challenge will remain significant… the timing will not change the fact that Iran is working towards nuclear military capabilities and in certain scenarios can shorten the timeline.”
