Did North Korea Really Attack Sony? - The Atlantic

Final paragraph from a Bruce Schneier Sony attack reality check

"I worry that this case echoes the “we have evidence—trust us” story that the Bush administration told in the run-up to the Iraq invasion. Identifying the origin of a cyberattack is very difficult, and when it is possible the process of attributing responsibility can take months. While I am confident that there will be no U.S. military retribution because of this, I think the best response is to calm down and be skeptical of tidy explanations until more is known."
