Re: ..so what WAS StuxNet if not a 'cyber-attack'?
I think he's working with the 'single campaign does not a war make' philosophy. I've seen other real generals post similar thoughts. They may have concerns about how cyber operations affects an actual attack, but unless the cyber attack itself generates actual human casualties, it isn't an attack. They tend not to attempt to address the "if patients at a hospital die as a result of a coordinated/state planned malware attack, does they constitute casualties" question.
I'm wishy-washy on this point. I see and understand what they are saying, and agree to some extent, but also think the concept of a cyber attack is a useful one in other contexts. It may be a bit like the old justice's definition of porn, we might not be able to define it, but we'll know what it looks like after the first one happens. Until then, they are pre-cursors and not real cyber attacks.
