VIENNA - Iran's latest claim of a breakthrough in its nuclear program appears unlikely to bring it any closer to having atomic bombs, but serves rather as another defiant message to the West.

This week's announcement that Iran has successfully made and tested fuel rods for use in nuclear power plants appeared designed to show that sanctions are failing to halt its technical advances and to strengthen its hand in any renewed negotiations with the major powers.
"The development itself doesn't put them any closer to producing weapons," said Peter Crail of the Arms Control Association, a Washington-based research and advocacy group.
It could be a way of telling Tehran's foes that time is running out if they want to revive an atomic fuel swap deal that collapsed two years ago but is still seen by some experts as offering the best chance to start building badly needed trust.
Diplomats believe Iran has in the past overstated its nuclear progress to gain leverage in its standoff with Western capitals, and the testing of domestically made fuel does not mean the country is about to start using it to run reactors.
"It is a step in the direction of no longer needing supply from other countries," said Associate Professor Matthew Bunn of Harvard University's Kennedy School.
"But it will be a good number of months or years before it will be at the point where they no longer need supply from other countries."
Even if the fuel step is confirmed, it is unlikely to add much to already growing Western suspicions that Iran is seeking the capability to manufacture nuclear arms, a charge it denies.
Iran "still needs to pretend" that it is processing uranium in order to make nuclear fuel and not for weapons, a Western diplomat in Vienna said.Negotiating tactic?
Iran's announcement that it had produced the fuel rods and inserted them in a research reactor core in Tehran coincided with an escalating war of words with the West, in a long-running nuclear row that could spark a wider Middle East conflict.
Tehran has threatened to take action
if the US Navy moves an aircraft carrier into the Gulf, its most
aggressive warning yet after weeks of saber-rattling as new US and
European sanctions take a toll on its economy.
But Iran is also sending out more conciliatory signals: inviting senior UN nuclear inspectors to visit and suggesting a resumption of long-stalled talks
with the six big powers - the United States, Russia, France, Germany, China and Britain.
That may be a sign of nervousness within the leadership - as the Iranian currency tumbles to a record low
against the US dollar - that tightening sanctions might hurt the major oil producer's lifeblood crude exports.
Sunday's statement of a fuel breakthrough once again underlined Iran's
determination to press ahead with an atomic program its clerical rulers
regard as a source of power and prestige.
"They announced the
fuel rod production and called for talks at the same time, suggesting
the fuel rod is intended more as negotiating leverage," said Crail of
the Arms Control Association.
The United States says the drive it leads to isolate Iran has slowed Tehran's nuclear program.
despite tougher sanctions and suspected sabotage, Iran is pressing
ahead with the work and its stockpile of low-enriched uranium would be
sufficient for at least two atomic bombs if refined much further.
experts give different estimates of how quickly Iran could assemble a
nuclear weapon if it decides to do so - ranging from as little as six
months to a year or more.
In 2010, Iran alarmed the West by
starting to enrich uranium to a fissile purity of 20 percent, up from
3.5 percent usually required for power plants, bringing it significantly
closer to the 90 percent level required for weapons.
it was forced to take this step to make fuel for the Tehran research
reactor after failing to agree terms for a deal to obtain it from the
West. But many analysts doubted it would be able to convert its uranium
into special reactor fuel.
Harvard's Bunn described Iran's
reported nuclear advance this week as "an early test" of whether it
could make fuel able to withstand the radiation, temperature and
pressure conditions that exist in a reactor.
"It is a long road
yet before you would have fuel that you could actually load in the
reactor as the fuel that was going to sustain that reactor's operation,"
