Iran has a facility at Natanz where it enriches uranium. According to the treaties that it has signed Iran is allowed to have that facility, and it is allowed to use that facility to enrich uranium. A paranoid, warmongering nation keeps working itself up into a lather about that, and constants hints that is gonna blow that plant to Kingdom Come. So what does Iran do? It does the sensible thing: it starts building another plant in case that little upstart nation attacks its existing plant and - as required by its treaty obligations - it informs the IAEA that this is what is going down. Excuse me, but what's all the fuss about? If Iran was allowed to build Natanz (and it was) then it is also allowed to build this plant. And. It. Is.
