“It’s hard for me to express how bad this is, and it doesn’t matter that no one has found a smoking gun in this immediately. … We’re going to get people killed because of this,” said former CIA Director Michael Hayden. “The amount of damage will be incalculable in all the meanings of the word — beyond measure and hard to measure.”…

Rep. Jane Harman (D-Calif.), who is deeply involved in national security issues, said her staff visited the WikiLeaks site and saw plenty of information the Taliban can exploit.

“There are names of State Department officials, U.S. military officials, Afghans and the cities in which they live in the materials,” said Harman, chairwoman of the House Homeland Security Subcommittee on Intelligence. By posting them online, she said, “we’ve just served up a target list and an enemies list to the Taliban. … Real people die when sources and methods are revealed.”

Former CIA officer Robert Baer said the disclosures will make Afghans less likely to aid U.S. forces.
