The top U.S. military official said Sunday that Iran has sufficient fissile material for a nuclear weapon, declaring it would be a "very, very bad outcome" should Tehran move forward with a bomb.

Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, offered the assessment when questioned in a broadcast interview about a recent report by the U.N. nuclear watchdog on the state of Iran's uranium enrichment program, which can create nuclear fuel and may be sufficiently advanced to produce the core of warheads.

Mullen was asked if Iran now had enough fissile material to make a bomb. He responded, "We think they do, quite frankly. And Iran having a nuclear weapon I've believed for a long time is a very, very bad outcome for the region and for the world."

Mullen's spokesman, Capt. John Kirby, said Mullen was referring only to the International Atomic Energy Agency's finding that Iran has processed 2,222 pounds (1,010 kilograms) of low-enriched uranium.

Experts differ on whether that stockpile is enough to allow Iran to further refine the material and arm one weapon, should it choose to do so. Experts also disagree about how long it would take Iran to make the leap to a deployable weapon. Iran is continuing an accelerated nuclear development program.

State Department spokesman Robert A. Wood said Sunday that it was not possible say how much fissile material Iran has accumulated.

"There are differing view not only outside government but also inside the government" on how far Iran has gone, Wood said. He added that while he was not suggesting Mullen was incorrect, "We just don't know" exactly how much fissile material Iran now holds.

"We are concerned they are getting close" to having enough to build a nuclear weapon, he added. Wood spoke to reporters traveling with Secretary of State Hillary Rodham Clinton in Egypt.

Defense Secretary Robert Gates, who like Mullen appeared on the Sunday talk shows, did not go as far as Mullen. The Iranians, Gates said, are "not close to a weapon at this point and so there is some time" for continued diplomatic efforts.
