The State Dept. isn't playing second fiddle.  They simply can  <i>NOT</i> come out as publicly as Google did, for many reasons.  As the "official" foreign voice of the US Govt there are serious repercussions to coming right out and accusing China.  Secondly, they would not tip their hand on any intelligence they received, or were actively receiving, on Chinese infiltrations in cyberspace.<p>While our Gov't isn't very good at some things, I can guarantee that they were aware of what was going on.  There have been many well-publicized instances over the past 10 years where the Govt' has uncovered intrusions into commercial companies.
