I don't see any military strike in the near future. After all, the massive amounts of sanctions and the extremely low value of the Iranian dollar (rail/toman) was put in place to cause public discontent as unemployment sores and food prices doubles/triples in price the public will, as most hope, cause the Iranian people to rise up against the mullah leaders.
I don't think anyone really wants massive wars all over the ME and most know it is best if the Iranian people sort out their dictatorship problem on their own.
Also,not to forget, that striking Iran would play into mullahs hands. It is the only thing that could potentially bring the majority of Iranians to suport the insane clerical leaders.
