Will Israel Attack Iran?

Last year people I respect were worrying that an Israeli attack on Iranian nuclear facilities was imminent, but now I am seeing reports everywhere that suggest there will be no attack. Among the reasons given:

• Political turmoil in the Arab world is a complicating factor;
• the Iranian government is in trouble with its own citizens and internally divided;
• the new Israeli anti-missile systems, such as Iron Dome, are working better than expected;
• the Iranian nuclear program is too decentralized for an attack to be very effective;
  
• the Obama administration is adamantly opposed;
  
• the Israeli government is itself divided, with several former heads of the army and Mossad publicly opposing a strike;former Mossad chief Meir Dagan called the plan to launch an air strike against Iran "the stupidest thing I have ever heard."

I think this falls into the category of good news.
