U.S. Defense Secretary Leon Panetta briefs the media at the Pentagon Briefing Room in Washington in this January 26, 2012 file photo. Panetta believes there is a growing possibility Israel will attack Iran as early as April to stop Tehran from building a nuclear bomb, U.S. media reported on February 2, 2012. The Washington Post first reported that Panetta was concerned about the increased likelihood Israel would launch an attack over the next few months. CNN said it confirmed the report, citing a senior Obama administration official, who declined to be identified. REUTERS/Kevin Lamarque/Files (UNITED STATES - Tags: POLITICS MILITARY PROFILE ENERGY)
