Could the hullabaloo about WikiLeaks be more hype than substance? NBC News’ Michael Isikoff reports that the Pentagon’s ongoing review has found that, so far, the WikiLeaks’ document dump has not endangered U.S. national security or American troops in the field. “The initial Pentagon assessment is far less dramatic than initial statements from the Obama White House Sunday night,” he writes. A Pentagon spokesman adds that none of the documents reviewed so far are classified above “secret,” the lowest level of sensitivity. Andrew Exum, fellow at the Center for a New American Security, agrees on The New York Times op-ed page. “I’m a researcher who studies Afghanistan and have no regular access to classified information, yet I have seen nothing in the documents that has either surprised me or told me anything of significance,” he writes in a column that takes on WikiLeaks founder Julian Assange. It should be noted that WikiLeaks has not yet published 15,000 of the documents, which it says it is reviewing because of their sensitive nature.
