If you've been following the news, you should have heard that a recent National Intelligence Estimate says that Iran dropped its nuclear weapons program in 2003. George Bush has countered by claiming that this recent NIE is a "warning signal" -- rather than, say, seeing the positives that apparently international pressure can put a nation of nuclear arms.
You can download and read the public version of the NIE by clicking here. Here's the relevant section heading bits:
A. We judge with high confidence that in fall 2003, Tehran halted its nuclear weapons program; we also assess with moderate-to-high confidence that Tehran at a minimum is keeping open the option to develop nuclear weapons. We judge with high confidence that the halt, and Tehran’s announcement of its decision to suspend its declared uranium enrichment program and sign an Additional Protocol to its Nuclear Non-Proliferation Treaty Safeguards Agreement, was directed primarily in response to increasing international scrutiny and pressure resulting from exposure of Iran’s previously undeclared nuclear work.
B. We continue to assess with low confidence that Iran probably has imported at least some weapons-usable fissile material, but still judge with moderate-to-high confidence it has not obtained enough for a nuclear weapon. We cannot rule out that Iran has acquired from abroad—or will acquire in the future—a nuclear weapon or enough fissile material for a weapon. Barring such acquisitions, if Iran wants to have nuclear weapons it would need to produce sufficient amounts of fissile material indigenously—which we judge with high confidence it has not yet done.
C. We assess centrifuge enrichment is how Iran probably could first produce enough fissile material for a weapon, if it decides to do so. Iran resumed its declared centrifuge enrichment activities in January 2006, despite the continued halt in the nuclear weapons program. Iran made significant progress in 2007 installing centrifuges at Natanz, but we judge with moderate confidence it still faces significant technical problems operating
them.
D. Iranian entities are continuing to develop a range of technical capabilities that could be applied to producing nuclear weapons, if a decision is made to do so. For example, Iran’s civilian uranium enrichment program is continuing. We also assess with high confidence that since fall 2003, Iran has been conducting research and development projects with commercial and conventional military applications—some of which would
also be of limited use for nuclear weapons.
E. We do not have sufficient intelligence to judge confidently whether Tehran is willing to maintain the halt of its nuclear weapons program indefinitely while it weighs its options, or whether it will or already has set specific deadlines or criteria that will prompt it to restart the program.
F. We assess with moderate confidence that Iran probably would use covert facilities—rather than its declared nuclear sites—for the production of highly enriched uranium for a weapon. A growing amount of intelligence indicates Iran was engaged in covert uranium conversion and uranium enrichment activity, but we judge that these efforts probably were halted in response to the fall 2003 halt, and that these efforts probably had not been
restarted through at least mid-2007.
G. We judge with high confidence that Iran will not be technically capable of producing and reprocessing enough plutonium for a weapon before about 2015.
H. We assess with high confidence that Iran has the scientific, technical and industrial capacity eventually to produce nuclear weapons if it decides to do so.
Notably, this public version of the NIE was (naturally) not released at the request of George Bush. You can click here to read Dr. Donald Kerr's statement about why they released the information. Here's the punchline, in his words:
The decision to release an unclassified version of the Key Judgments of this NIE was made when it was determined that doing so was in the interest of our nation’s security. The Intelligence Community is on the record publicly with numerous statements based on our 2005 assessment on Iran. Since our understanding of Iran’s capabilities has changed, we felt it was important to release this information to ensure that an accurate presentation is available. While the decision to release the declassified Key Judgments was coordinated in discussion with senior policy makers, the IC took responsibility for what portions of the NIE Key Judgments were to be declassified.
"...we felt it was important to release this information to ensure that an accurate presentation is available."
"...doing so was in the interest of our nation's security."
The office of the DNI is, perhaps, not as compliant as George Tenet was.
