As Cheney Preps Another Langley Visit to Get His War On

No Proof Found of Iran Arms Program
Uranium Traced to Pakistani Equipment
By Dafna Linzer

Traces of bomb-grade uranium found two years ago in Iran came from contaminated Pakistani equipment and are not evidence of a clandestine nuclear weapons program, a group of U.S. government experts and other international scientists has determined.

"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...

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...

U.S. officials, eager to move the Iran issue to the U.N. Security Council -- which has the authority to impose sanctions -- have begun a new round of briefings for allies designed to convince them that Iran's real intention is to use its energy program as a cover for bomb building. The briefings will focus on the White House's belief that a country with as much oil as Iran would not need an energy program on the scale it is planning, according to two officials...

Unless, of course, they had enough foresight to realize the oil wouldn't last forever.

Iran built its nuclear program in secret over 18 years with the help of Abdul Qadeer Khan, a top Pakistani official and nuclear scientist who sold spare parts from his country's own weapons program to Iran, Libya and North Korea. Khan's black-market dealings were uncovered in 2003. He confessed on national television, was swiftly pardoned by Pakistan's president, Gen. Pervez Musharraf, and is now under house arrest.

Pakistan has denied IAEA inspectors access to Khan and to the country's nuclear facilities, but earlier this year it agreed to share data and some equipment with the inspectors to expedite the Iran investigation. Among the equipment were discarded centrifuge parts that match those Khan sold to Iran.

John R. Bolton, now U.S. ambassador to the United Nations, served as the administration's point man on nuclear issuesduring President Bush's first term. He suggested during congressional testimony in June 2004 that the Iranians were lying about the contamination.

"Another unmistakable indicator of Iran's intentions is the pattern of repeatedly lying to and providing false and incomplete reports to the IAEA," Bolton said. "For example, Iran first denied it had enriched any uranium. Then it said it had not enriched uranium more than 1.2 percent. Later, when evidence of uranium enriched to 36 percent was found, it attributed this to contamination from imported centrifuge parts..."

Bolton has evidently exaggerated, since this uranium contaminated the centrifuge before the Iranians purchased it. Since enriched uranium is depleted of other elements, a trace sample from the centrifuge should have a certain degree of isotopic purity. In fact, the level of uranium decay products in the sample tells you precisely when the centrifuge was last used to purify uranium. Apparently the data show that the centrifuge hasn't been used for the purpose Bolton suggests.

In the meantime, European officials convened an IAEA board meeting two weeks ago to discuss Iran's actions and sought a new report for this week on its program. But the report was pushed back to Sept. 3 so that the group of scientists, including officials from the Energy Department, could meet one last time to draft an account of its findings, according to U.S. and European officials.

The IAEA had put together the group of experts in an effort to foster cooperation but also to eliminate the possibility that its findings would be challenged by the White House, officials said. In the run-up to the Iraq invasion in March 2003, the White House rejected IAEA findings that cast doubt on U.S. assertions about then-Iraqi President Saddam Hussein's arsenal. The IAEA findings turned out to be correct, and no weapons of mass destruction have been found in Iraq.
