Crucially, Iraq has lacked fissile material (enriched uranium or plutonium).
But no one will build you one of these plants to make the 20%, high enriched material.
FORBES: Trying An Educated Guess Over This Iran And The Bomb Thing
Beyond this, Mr Netanyahu argued, it might only be a matter of weeks or months before it had sufficient highly-enriched material for a bomb.
The government offered twenty-five-million-dollar matching grants to companies that could devise a way to produce the material domestically, without using enriched uranium.
He cited the country's production of 20%-enriched fuel as material needed to make medicine for more than 1 million Iranian cancer patients.
Acquiring nuclear weapons requires three elements: fissile material (such as highly enriched uranium, HEU, or plutonium), a delivery system and a warhead.
As the chart shows, the amount of potentially weapons-usable nuclear material either highly enriched uranium or separated plutonium under inspection has increased far faster than the funds available for safeguarding it.
ECONOMIST: Troubling flaws in the world's nuclear safeguards
In the talks leading up to the July deal, America had encouraged India to cap voluntarily its production of fissile material highly-enriched uranium and plutonium for bombs as the official nuclear five have done.
But the country in 2010 publicly revealed its effort to develop highly enriched uranium, another material that can trigger a nuclear explosion.
Since 2010, Iran has been enriching uranium to a level of 20%, an important technological step towards being able to produce more highly enriched weapons-grade material.
The United States and other leading nations have been negotiating with Iran to send low-enriched uranium abroad to be turned into material for use in medical research and treatment at a reactor in Tehran.
However, an IAEA official who asked not to be named cautioned against drawing such dramatic conclusions from the data, saying Iran's stock of low-enriched uranium would have to be turned into highly enriched uranium to be weapons-grade material.

The reference to a test of a "higher level" could suggest North Korea has reached a point where it can test a weapon made from highly enriched uranium, rather than the plutonium fissile material used in its two previous tests.
However, an IAEA official who asked not to be named cautioned against drawing such dramatic conclusions from the data, saying Iran's stock of low-enriched uranium would have to be turned into highly enriched uranium to qualify as weapons-grade material.
CNN: U.S.: Iran has material for nuclear bomb but still 'not close'
The authority has also proposed moving other material called "exotics", which includes fuel containing highly-enriched uranium, from Dounreay to Sellafield at a later date.
BBC: Nuclear material moved by train from Scotland to England
The prototype light-water reactor that North Korea is constructing at Yongbyon, and which requires enriched-uranium fuel, could add to the fissile material stockpile when it is completed, possibly by the end of the year.
P-1 centrifuges, configured to produce highly enriched uranium rather than the civilian sort, to produce enough fissile material for a bomb a year.
Current law is aimed at phasing out U.S. exports of highly enriched uranium (HEU) precisely to reduce the risk of the material being stolen or diverted by proliferating states for nuclear weapons production.
CENTERFORSECURITYPOLICY: Kyl and Schumer move to monitor uranium exports
When enriched to a high degree, uranium can be used for weapons-grade material.
The IAEA said Iran had continued its production of 20% enriched uranium, though the majority of the uranium had been converted to fuel, which is not material that can be used for a weapon.
