The Iranians have only a few thousand centrifuges enriching Uranium to 20%. It takes about a year to enrich to a level of some 90% as required for bombs. Since all the known centrifuges are under IAEA supervision, we know that Iran did not yet start to enrich for a bomb. Therefore, the 1 year Barak gives for Iran being capable of constructing their bomb should START running from the time IAEA are barred from inspection or see enrichment over 20%, not from now. Barak is smart, and if he is misleading he is doing it on purpose. But the rest of the world are not idiots either, unlike what Barak thinks.
