The US will be the biggest loser in a Cyber War?
Interesting coincidence that I'm currently reading Cyber War by Richard Clarke and Robert Knake. The main point is that the US probably has powerful offensive capabilities but almost NO defensive capabilities, which is amplified by our extreme reliance and even dependency on our computer networks.
In contrast, China is playing BOTH offense and defense. The Great Firewall of China is actually part of the defensive perimeter, not merely censorship. Private companies don't get to tell the government that network security might reduce their profits. Even more importantly, it's much harder for them to bribe politicians to look away from the problems.
This article should be regarded as another shot across the bow.
