So here we have a very specific, targeted weapon used successfully by “unknown” sources. Cyberwar? I think not. Cyberattack? Yes. The attack came in the form of a program, placed preemptively and with malicious intent.
We are only humans, we are probably wrong thinking in our complacency, most of the time. These “blowouts” must be achieved from time to time. If we've been fighting a nonstop cyberwar since the inception of the possibility, and see no possible end, how is this any different than in the non-cyber world? The real world is the same, it is made up by those of us who choose to change it. One can only hope we each do so correctly.
