For almost a decade Iran has denied that their nuclear program has any military application and that it is solely focused on the production of energy for civilian use. That makes is a bit difficult to explain their need for a ” nuclear trigger :
The notes, from Irans most sensitive military nuclear project, describe a four-year plan to test a neutron initiator, the component of a nuclear bomb that triggers an explosion. Foreign intelligence agencies date them to early 2007, four years after Iran was thought to have suspended its weapons programme.
An Asian intelligence source last week confirmed to The Times that his country also believed that weapons work was being carried out as recently as 2007 specifically, work on a neutron initiator.
The technical document describes the use of a neutron source, uranium deuteride, which independent experts confirm has no possible civilian or military use other than in a nuclear weapon. Uranium deuteride is the material used in Pakistans bomb, from where Iran obtained its blueprint.
Although Iran might claim that this work is for civil purposes, there is no civil application, said David Albright, a physicist and president of the Institute for Science and International Security in Washington, which has analysed hundreds of pages of documents related to the Iranian programme. This is a very strong indicator of weapons work.
