North Korea’s intimidation of Hollywood cannot go unanswered

[Commentary] Both the cyberattack on Sony and the coercion are unacceptable and cannot go unanswered. Congress has tried but failed to approve legislation that would have allowed the federal government to work more closely with the private sector to protect corporate networks. We hope the 114th Congress will act soon. The nation would not tolerate a ballistic missile landing in a movie lot; how should it respond to a cybermissile and a direct threat of violence? President Barack Obama has signed a directive laying out criteria for the use of US cyberforces for offense and defense. We hope he is reading it anew.
