The Hill reports that "Edward Snowden’s disclosures about American spy powers directly led to the end of a critical program in Afghanistan, the nation’s top spy said on Wednesday."
"By forcing the end of the program that recorded practically every cellphone call in the country — as well as scuttling other efforts — Snowden 'has done untold damage' to U.S. intelligence, Director of National Intelligence James Clapper said... The spy chief appeared to be referring to a May 2014 story on The Intercept — the online news outlet spearheaded by Greenwald — outlining how the National Security Agency (NSA) was 'secretly intercepting, recording and archiving the audio of virtually every cellphone conversation' in two nations."
"The Intercept said that the program was taking place in the Bahamas and another country, which it declined to name because of concerns that doing so could lead to violence... Days later, WikiLeaks publicly identified the country as Afghanistan. The program 'was the single most important source of force protection warning for our people in Afghanistan,' Clapper said."
