Most problematic, perhaps, it will have satisfy the International Atomic Energy Agency IAEAA) that it is cooperating with the agency's investigation into evidence of past work on nuclear weaponisation.
A recent report on Russia's "weaponisation of information" published by the Institute of Modern Russia, a New York-based think tank run by the son of former oligarch and Putin critic Mikhail Khodorkovsky, argued that the Kremlin is wielding outlets like Sputnik News to not just persuade, but also to "sow confusion via conspiracy theories and proliferate falsehoods".
But although the report does not fit neatly into Dick Cheney's plan for building a case for military intervention in Iran, the NIE assessment that Iran had a covert weaponisation programme in the past that could be restarted at any time works to the hawks' advantage.
That programme was about "weaponisation": the fiddly business of making a device that can set off a chain reaction in nuclear fuel.
Lastly and crucially, Iran must demonstrate its faith in the deal by admitting its past work on weaponisation.
That would leave each country with just over 1,000 such weapons, if Mr Putin reciprocated.Mr Obama talked of rejecting "the nuclear weaponisation that North Korea and Iran may be seeking": a cautious form of words that avoided early confrontation with Iran's president-elect, the avowed moderate Hassan Rohani.
A stock of low-enriched uranium could give it a break-out capacity to build a weapon in a matter of a few months, depending on how far Iran had got with its earlier weaponisation work.
When they left, three years ago, the inspectors were convinced that Iraq was still concealing the true scale of its production and weaponisation of VX, a potent nerve gas.
Today's youth often assumes that sending a tweet constitutes protest.Metin Toksoz-Exley BostonThe debate on Iran's nuclear programme* SIR – Iran has not crossed the nuclear threshold, usually defined as weaponisation (Letter from Simon Henderson and Olli Heinonen, July 6th).
Some say Mr Obama should heed an argument, now gaining ground in the West, that it is too late to stop Iran processing uranium as a precondition for negotiation, and that the least bad course now would be to push for intrusive international monitoring of Iran's nuclear activity in the hope that it remains civilian and not hell-bent on weaponisation.
But the weaponisation work the NIE thinks was halted is easy to restart and easy to hide.Hence the fury of even some of America' s closest European allies at the NIE's selective and then mangled message.
