We have been told to expect attacks since 9/11; that cyberterrorists would try to cripple our power system, disable air traffic control and emergency services, open dams, or disrupt banking and communications. But so far, nothing's happened. Even during the war in Iraq, which was supposed to increase the risk dramatically, nothing happened. [..]

[cyberterrorism] It's the equivalent of soccer hooligans taking out national frustrations on another country's fans at a game. It's base and despicable, and it causes real damage, but it's cyberhooliganism, not cyberterrorism.
