That also keeps the "good guys" thinking they're safe, when in fact there could be a backdoor for the Chinese government that sends over all messages that say "falun gong." As demonstrated by the recent leak at the NSA perhaps we should be investing in as much cyber defense as offense before a cyber terrorist attack occurs.
From everything I've learned about security, offense is much, much more effective dollar for dollar and that any concerted effort of creating an impenetrable shield would result in a cyber Maginot Line.
An all out cyber war would be scary as there isn't any procedure or policy for descalation once started, no white flag.
What's especially scary is that the government wastes all this time and money surveillaning people's online habits when the electric grid, probably the number one target in the event of a cyber war, is so defenseless that a squirrel can effectively take out electricity for the Eastern seaboard.
