I found this line LOL funny...
"If you shut down our power grid, maybe we will put a missile down one of your smokestacks," said a military official.
The target area is only two meters wide. That's impossible! Even for a computer.
Cyber warfare is a main strategy for China's military. China's official military doctrine calls for the use of cyber warfare to soften up a target by disrupting command, control, communications, and intelligence (C3I) functions before launching a conventional attack. Also, China's military regularly hosts hacking competitions to identify the best hackers in China for "recruitment" to the military. I use the term recruitment loosely since if they decide they want you, you have no choice.
