[_Understated_]

I've long felt that WWIII will not be fought (initially, anyway) with tanks and bombs and such, but with computers.

What could be more effective for your enemy than taking out all your power stations and plunging your country into total darkness and chaos? Everything would run out in short order and people would turn on each other.

Saves having to mess the place up with bombs and you have plausible deniability within the international community.
