So now the country is engaged in painful soul-searching about whether NSA has gone too far and whether we should invite leaker Edward Snowden back for a ticker-tape parade. On the latter, Mr. Snowden has set the agency back perhaps a decade or more through the unrelenting disclosure of sources and methods. He and his supplicants at major press outlets here and abroad publish his revelations as if the national security of this country and the U.K. matter little. (To President Vladimir Putin: Give us Snowden. You already know everything from him.) One NSA slide from Mr. Snowden, for example, depicted an alleged NSA relationship with Skype. If there were terrorist communications on Skype, they are long gone, just like when NSA lost Osama bin Laden's communications through press leaks in 1998.
