The government IS able to keep big secrets

it is extraordinarily naive to think the government is incapable of keeping a large secret involving dozens, hundreds, or even thousands of people. I am reminded of this passage from the memoirs of Pentagon Papers whistleblower Daniel Ellsberg, who knows a thing or two about how government secrecy works. Not only is the idea that you can’t keep secrets in Washington “flatly false,” Ellsberg writes, but by repeating it you’re doing the government’s work for them. [Such sayings] are in fact cover stories, ways of flattering and misleading journalists and their readers, part of the process of keeping secrets well. Of course eventually many secrets do get out that wouldn’t in a fully totalitarian society. But the fact is that the overwhelming majority of secrets do not leak to the American public … The reality unknown to the public and to most members of Congress and the press is that secrets that would be of the greatest import to many of them can be kept from them reliably for decades by the executive branch, even though they are known to thousands of insiders. [emphasis added] As a simple example, which Hersh himself stated in this fascinating On The Media interview, how many people knew about the Bush administration’s manipulation of intelligence before the Iraq war? Hundreds? Over a thousand? How many knew about the NSA’s mass phone metadata program aimed at Americans until Edward Snowden revealed it? A thousand? Ten thousand? It stayed secret for more than seven years until a single person—a contractor, not an NSA employee—exposed it.
