From the article at TechCrunch:
Snowden points out that the White House’s own independent review panels have shown that not a single program has stopped an imminent terrorist attack on the United States. He does not believe the public is aware of just how disastrous these policies could backfire and questions the value of such programs that leave our own information vulnerable.
We spend much more on research and development, compared to the rest of the world. So when it comes to our cyber security says Snowden, “We have more to lose than any other nation on Earth.”
Snowden said he didn’t want to overhype the problem, “Nobody’s going to press a key on their keyboard and bring down the government.” But he did emphasize that the threats from foreign governments were real and that we should be focusing more on the defense of our own information than focusing on others.
