From the New York Times:
Last March, the federal government set up a Web site to make public a vast archive of Iraqi documents captured during the war. The Bush administration did so under pressure from Congressional Republicans who had said they hoped to “leverage the Internet” to find new evidence of the prewar dangers posed by Saddam Hussein.
But in recent weeks, the site has posted some documents that weapons experts say are a danger themselves: detailed accounts of Iraq’s secret nuclear research before the 1991 Persian Gulf war. The documents, the experts say, constitute a basic guide to building an atom bomb.
Last night, the government shut down the Web site after The New York Times asked about complaints from weapons experts and arms-control officials. A spokesman for the director of national intelligence said access to the site had been suspended “pending a review to ensure its content is appropriate for public viewing.”
Officials of the International Atomic Energy Agency, fearing that the information could help states like Iran develop nuclear arms, had privately protested last week to the American ambassador to the agency, according to European diplomats who spoke on condition of anonymity because of the issue’s sensitivity. One diplomat said the agency’s technical experts “were shocked” at the public disclosures.
Early this morning, a spokesman for Gregory L. Schulte, the American ambassador, denied that anyone from the agency had approached Mr. Schulte about the Web site.
The documents, roughly a dozen in number, contain charts, diagrams, equations and lengthy narratives about bomb building that nuclear experts who have viewed them say go beyond what is available elsewhere on the Internet and in other public forums. For instance, the papers give detailed information on how to build nuclear firing circuits and triggering explosives, as well as the radioactive cores of atom bombs.
“For the U.S. to toss a match into this flammable area is very irresponsible,” said A. Bryan Siebert, a former director of classification at the federal Department of Energy, which runs the nation’s nuclear arms program. “There’s a lot of things about nuclear weapons that are secret and should remain so.”
The government had received earlier warnings about the contents of the Web site. Last spring, after the site began posting old Iraqi documents about chemical weapons, United Nations arms-control officials in New York won the withdrawal of a report that gave information on how to make tabun and sarin, nerve agents that kill by causing respiratory failure.
The campaign for the online archive was mounted by conservative publications and politicians, who said that the nation’s spy agencies had failed adequately to analyze the 48,000 boxes of documents seized since the March 2003 invasion. With the public increasingly skeptical about the rationale and conduct of the war, the chairmen of the House and Senate intelligence committees argued that wide analysis and translation of the documents — most of them in Arabic — would reinvigorate the search for clues that Mr. Hussein had resumed his unconventional arms programs in the years before the invasion. American search teams never found such evidence.
