Iran has enough uranium for five nuclear weapons, claims US thinktank

21. Where to start here?

First, as another response has aptly pointed out here, consider the source of this information.

Second, consider the science behind this claim. Separating U235 (the weaponizable isotope) from spent fuel is a very difficult task. A very difficult task. It is not something you can hide if you are intent on doing it. You cannot do it chemically since all uranium is chemically identical. Instead you have to do it by mass. But that is an extremely difficult task which takes rather large resources, none of which could be hidden from, let's say, US spy satellites.

But people in the US are so scientifically illiterate, to say nothing of the press, that they can get away with this kind of reportage.

If Iran is making a nuke, Obama will know about it well in advance. In the Iran talks, he is negotiating from strength.
