Meir Dagan, the chief of the Mossad overseas intelligence agency, talks to the Knesset's foreign affairs and defence committee in Jerusalem 17 November 2003. Dagan said that Iran's nuclear program poses the biggest threat to Israel's existence since the country's creation more than five decades ago. In a rare appearance Dagan said Iran was now close to the "point of no return" in developing nuclear arms.
