Below is part of an article that appears in Al Jazeera which examines exactly what is in the latest IAEA report  . If true , it is US and Israeli inspired PR and with a large helping of Bull Shit .
Well worth reading and frightening if you believe that these nice people want a pre emptive air strike much sooner than later .
There are definitely very powerful and influential elements within both countries that  would bomb specific installations in Iran tomorrow . Or earlier .
It is impossible to make an informed layman opinion because we have no idea who is telling the truth .imo

Yet the report does not conclude that Iran has restarted its nuclear weapons programme, which was officially suspended in late 2003. The IAEA certified that Iran has not diverted any of its stockpiled low-enriched uranium for military purposes.

And US officials, citing their own intelligence, said that Iran "still has not mastered" any of the complex technologies required to produce a nuclear weapon.

The report, in other words, seems largely to confirm what most analysts and intelligence services already believed: that Iran has studied how to design a nuclear weapon. But it offers no new evidence on how close Iran is to finishing one, analysts say, or even whether it is actively trying to build one.

"The report suggests that Iran is working to shorten the timeframe to building the bomb once and if it makes that decision," said a memo from the Arms Control Association, a Washington-based think tank. "But it remains apparent that a nuclear-armed Iran is still not imminent nor is it inevitable."

'Most of this is not new'

Many of the findings in the report which deal with a possible weapons programme - alleged modifications to the Shahab-3 missile, for example, which could be used to deliver a nuclear warhead - have been disclosed previously, either by Western intelligence services or in other IAEA reports.

"Most of this has been known to experts for several years," said Joseph Cirincione, the president of the Ploughshares Fund, a nuclear policy organisation in Washington. "What's different is that for the first time it's out of the... internal workings of the IAEA, and being presented on the world stage, with the imprimatur of the agency's head."

The report does attempt to add new details to several of these findings, particularly about the so-called "green salt project," an alternate method of enriching uranium. If successful, it could theoretically allow Iran to spin off a separate nuclear programme free of IAEA oversight. But experts say such an undertaking would be enormously difficult to keep secret.

The "green salt" programme was first publicly disclosed in 2006, based on information on a laptop which an unnamed source brought to the IAEA in 2004. Analysts have long questioned the authenticity of the files on that computer, often pejoratively dubbed the "laptop of death."

Mohamed ElBaradei, the former director of the IAEA, admitted in the past that the agency often struggled to verify information on Iran's nuclear programme, much of it supplied by Western governments.

Tuesday's release does reveal a few new details about Iran's research. There is the "explosives vessel," for example, a large cylinder built at the Parchin military complex southeast of Tehran, which is used to test nuclear devices, according to the IAEA.

"From independent evidence, including a publication by the foreign expert referred to in paragraph 44 above, the Agency has been able to confirm the date of construction of the cylinder and some of its design features (such as its dimensions), and that it was designed to contain the detonation of up to 70 kilograms of high explosives."

The IAEA calls the vessel a single-use structure, a "strong indicator of possible weapon development."

An understated reaction

There was little immediate reaction to the report in Washington or in European capitals. The White House called the report significant, but emphasised the questions it failed to answer.

"The IAEA report does not assert that Iran has resumed a full-scale nuclear weapons program, nor does it have a conclusion about how advanced those activities are, but clearly indicates there are activities of concern," said a senior administration official.
