the real military networks should be well-prepared for cyberattacks, cept for maybe a few geniuses, you get that once in a while. even the hardware required by military has its own special standards, so hacking a military target is nothin like hacking a civie computer. but its more worthwhile to attack civie targets. i doubt the US would want to pull the plug on China just on the basis that there are possible cyber attacks. when push comes to shove, you never know where the attacks are really coming from. and really disconnecting internet service with China will cost the everyone way too much for anyone to bare.
