From Foreign Policy:

The director at Carnegie Endowment for International Peace had this to say:

Nothing is clear, yet. For months, I have told interviewers that no senior political or military official was seriously considering a military attack on Iran. In the last few weeks, I have changed my view. In part, this shift was triggered by colleagues with close ties to the Pentagon and the executive branch who have convinced me that some senior officials have already made up their minds: They want to hit Iran.
