When President Geroge W. Bush assumed office in 2001, Iran was not a nuclear power state. However, when he leaves office next January, Iran will either have acquired the status or be on the verge of having done so. Listen to its president, Mahmoud Ahmadinejad, and you hear that Iran has 3000 operationg centrifuges and is now installing an addiotnail 6000 IR-2 centrifuges that will be five times as efficient as those already operating.  Even if President Ahmadinejad exaggerates the exact status of the Iranian efforts, the Iranians probably will solve the technological problems that have limited their ability to operate their centrifuges on a non-stop basis within a year;s time.  And, once they have done s, they will be able to enrich uranium and stockpile fissionalbe material.
