By all accounts there is no evidence Iran is even developing a nuclear weapon:

Recent assessments by American spy agencies are broadly consistent with a2007 intelligence finding that concluded that Iran had abandoned itsnuclear weapons program years earlier, according to current and former American officials. The officials said that assessment was largely reaffirmed in a 2010 National Intelligence Estimate, and that it remains the consensus view of America’s 16 intelligence agencies.
At the center of the debate is the murky question of the ultimate ambitions of the leaders in Tehran. There is no dispute among American, Israeli and European intelligence officials that Iran has been enriching nuclear fuel and developing some necessary infrastructure to become a nuclear power. But the Central Intelligence Agency and other intelligence agencies believe that Iran has yet to decide whether to resume a parallel program to design a nuclear warhead — a program they believe was essentially halted in 2003 and which would be necessary for Iran to build a nuclear bomb. Iranian officials maintain that theirnuclear program is for civilian purposes.
In Senate testimony on Jan. 31, James R. Clapper Jr., the director of national intelligence, stated explicitly that American officials believe that Iran is preserving its options for a nuclear weapon, but said there was no evidence that it had made a decision on making a concerted push to build a weapon. David H. Petraeus, the C.I.A. director, concurred with that view at the same hearing. Other senior United States officials, including Defense Secretary Leon E. Panetta and Gen. Martin E. Dempsey, the chairman of the Joint Chiefs of Staff, have made similar statements in recent television appearances."
The Israeli strike ironically could be what pushes Iran to develop nukes.
