Had the configuration of centrifuges at Natanz been longer in series Iran could already have produced enough Highly Enriched Uranium to make a bomb. This is a fact. Nor is it that difficult to produce a nuclear weapon using Highly Enriched Uranium. The man who headed the design of the Little Boy bomb (L-11) was A. Francis Birch, a chemist. The bomb design did not even have to be tested and was not equipped (as the Fat Man design was) with a self-destruction mechanism because it was absolutely certain to work. The construction of such a weapon requires nothing in the way of 'high technology' aside from the ability to produce the Uranium. Iran could already have a bomb. That is a most compelling fact when one considers that if Iran, as North Korea has, built a bomb no one would be talking about attacking it. WHAT Iran HAS done argues that their goal is reactor fuel.
