It would seem that August 22nd is suffering a bit of schedule slippage. But a slipped project is not the same as an abandoned project:

"The Germans tried using heavy water for its own atomic-weapons program during World War II, and for a solid technical reason: it eliminates the need for uranium enrichment to fuel reactors, which can then yield weapons-grade fissile material. It seems as though the Iranians want to cover all their bases in creating the fuel for nuclear weapons; they continue to pursue enrichment in parallel.

Ahmadinejad's construction of the heavy-water plant puts a stake in the heart of the argument that Iran only wants peaceful nuclear energy. Their multiple-tracked efforts to achieve plutonium production shows quite clearly that they have spent more effort than necessary to get simple civil nuclear power production. The incentive package offered by the West would have given it to them in any case."

Ho hum. I'm sure Mr. A(bomb) is quite a rational chap. No need to worry. Move along now...
