No Proof Found of Iran Arms Program

"The biggest smoking gun that everyone was waving is now eliminated with these conclusions," said a senior official who discussed the still-confidential findings on the condition of anonymity.
Scientists from the United States, France, Japan, Britain and Russia met in secret during the past nine months to pore over data collected by inspectors from the International Atomic Energy Agency, according to U.S. and foreign officials. Recently, the group, whose existence had not been previously reported, definitively matched samples of the highly enriched uranium -- a key ingredient for a nuclear weapon -- with centrifuge equipment turned over by the government of Pakistan.
Iran has long contended that the uranium traces were the result of contaminated equipment bought years ago from Pakistan. But the Bush administration had pointed to the material as evidence that Iran was making bomb-grade ingredients.
The conclusions will be shared with IAEA board members in a report due out the first week in September, according to U.S. and European officials who agreed to discuss details of the investigation on the condition of anonymity. The report "will say the contamination issue is resolved," a Western diplomat said.
U.S. officials have privately acknowledged for months that they were losing confidence that the uranium traces would turn out to be evidence of a nuclear weapons program. A recent U.S. intelligence estimate found that Iran is further away from making bomb-grade uranium than previously thought, according to U.S. officials.
