The Real Cost of Snowden has yet to be Paid

Regardless of how you feel about Edward Snowden’s domestic surveillance program revelations, it’s time to get real about the cost we are paying for Snowden’s leaks about America’s signals intelligence programs. In a conversation a few months ago with a very senior former US intelligence official, I was struck by their apocalyptic assessment of the damage Snowden’s leaks had caused America’s intelligence capabilities. While he naturally considered the domestic concerns overblown, he was even more upset at Snowden undoing of decades of groundbreaking American work securing our own communications and spying on foreign governments.

Success in signals intelligence relies almost entirely on the opponent not knowing where and how he is being spied upon. As soon as your methods are discovered, your opponent can evade your espionage or, even worse, spoof you with false intelligence. Be detailing the methods that the US uses to spy on other countries, Snowden’s revelations immediately and directly limited the NSA’s capabilities. We are just now beginning to see the fruit of that.
