WASHINGTON: As whistleblower website WikiLeaks gets ready to release some 400,000 secret military documents, the Pentagon said Friday it was scouring through an Iraqi war database preparing for potential fallout from such a release of information. The substantial release is set to dwarf the whistleblower website's publication of 77,000 classified US military documents on the war in Afghanistan in July, including the names of Afghan informants and other details from raw intelligence reports. Another 15,000 are due out soon. In order to prepare for Monday's anticipated release of sensitive intelligence on the US-led Iraq war, officials set up a 120-person taskforce several weeks ago to comb through the database and “determine what the possible impacts might be,” said Col. David Lapan, a Pentagon spokesman. The Department of Defense is concerned the leak compiles “significant activities” from the war, or SIGACTS, which include incidents such as known attacks against coalition troops, Iraqi security forces, civilians or infrastructure in the country. The data was culled from an Iraq-based database that contained “significant acts, unit-level reporting, tactical reports, things of that nature,” said Lapan, noting that Pentagon officials still do not know how many and which documents would be released. He urged WikiLeaks to return the documents to the US military, which he said found no need to redact them in the interim. “Our position is redactions don't help, it's returning the documents to their rightful owner,” Lapan said. “We don't believe WikiLeaks or others have the expertise needed. It's not as simple as just taking out names. There are other things and documents that aren't names that are also potentially damaging.” For the Iraq leak, Wikileaks is believed to be teaming up with the same news outlets as it did for the Afghanistan document dump – The New York Times, Britain's Guardian and Der Spiegel of Germany – and Newsweek magazine has reported that all partners would release the material simultaneously. The July release caused uproar in the US government, with Director of National Intelligence James Clapper and former CIA director Michael Hayden warning it could undermine the post-9/11 effort to break down walls between rival intelligence agencies.
