As customary, extracts from the latest report from the International Atomic Energy Agency are being fed by Western officials to the media with the scariest-possible interpretation.
The report says that Iran's stock of 20% uranium is still below the level of 250 kilogrammes needed for a single atomic bomb, with Tehran holding 182 kilogrammes and another 140.8 kilos in a state for civilian-only use.
Three diplomats, however, made sure that George Jahn of the Associated Press has the dramatic lede that Tehran "has installed close to 700 high-tech centrifuges in an upgrade of its uranium enrichment program since the start of the year". (Jahn apparently has forgotten that in January the diplomats were talking of 3000 centrifuges.)
Reuters recycles the line that "Iran is pressing ahead with the construction of a research reactor" using plutonium from the Arak heavy-water reactor.
As EA noted earlier this year, dissecting a scare story in The Daily Telegraph, plutonium is a natural by-product of heavy-water reactors, and other countries use it in their civilian programmes.
The unintentional humour, howver, comes from the Institute for Science and International Security, which has previously seen pink tarpaulins and doom-laden magnets as harbingers of Iran's sinister atomic plans. This time, the Institute warns, "Iran Laying Asphalt at the Suspect Parchin Site".
