Last week, The Times of London revealed a secret two-page Iranian document suggesting that Iran has been secretly working on a neutron initiator--the part of a nuclear bomb that triggers the explosion. Iranian President Mahmoud Ahmadinejad made his first public comment on the document during an interview set to air Monday on ABC World News. When confronted with a copy of the document by Diane Sawyer, Ahmadinejad refused to look at it, saying, "No, I don't want to see this kind of document. These are some fabricated papers issued by the American government." Senior White House adviser David Axelrod later called Ahmadinejad's accusation "nonsense." Ahmadinejad also dismissed Sawyer's questions about whether Iran is testing a nuclear initiator, and said, "I think that some of the claims about our nuclear issues have turned into a repetitive and tasteless joke."
