If the Chinese military is regularly hacking into the computers of U.S. organizations, as an American security firm says, it raises all sorts of questions about how the U.S. should respond.

Is this a job for the military or the intelligence agencies? What role should diplomats and trade officials be playing?

The report issued this week by the IT security consultancy Mandiant says it has traced the hacking activity to the People's Liberation Army's Unit 61398, which has "systematically stolen hundreds of terabytes of data from at least 141 organizations."
