Israel's prime minister [Benyamin Netanyahu] has ordered an investigation into alleged leaks of plans to attack Iran's nuclear facilities. According to the Kuwaiti newspaper al-Jarida, the main suspects are the former heads of the Mossad and the Shin Bet, respectively Israel's foreign and domestic intelligence agencies. Netanyahu is said to believe that the two, Meir Dagan and Yuval Diskin, wanted to torpedo plans being drawn up by him and Ehud Barak, the defence minister, to hit Iranian nuclear sites. The purpose of the leaks was to prevent an attack, which had moved from the stage of discussion to implementation. Both Dagan and Diskin oppose military action against Iran unless all other options - primarily international diplomatic pressure and perhaps sabotage - have been exhausted. In January the recently retired Dagan, a hawk when he was running the Mossad, called an attack on Iran the stupidest idea I've ever heard". The Kuwait paper has a track record of running stories based on apparently high-level leaks from Israeli officials. Even well-informed Israeli observers admit to being confused about what is going on behind the scenes. "It seems that only Netanyahu and Barak know," commented Amos Harel and Avi Issacharoff, both respected Haaretz writers. "While many people say Netanyahu and Barak are conducting sophisticated psychological warfare and don't intend to launch a military operation, top officials are still afraid."
