Nobel peace laureate and UN nuclear watchdog agency chief Mohamed ElBaradei appeared to warn Israel not to bomb Iranian atomic facilities in a newspaper interview published Saturday. "You cannot use force to prevent a country from obtaining nuclear weapons. By bombing them half to death, you can only delay the plans," ElBaradei was quoted as saying by the respected Oslo newspaper Aftenposten. "But they will come back, and they will demand revenge." The report said ElBaradei did not mention Israel but it was clear he was referring to the Jewish state's increasingly open discussion over whether to protect itself by bombing Iranian facilities it suspects are being used in a possible secret nuclear weapons program.
