The Stuxnet computer worm that damaged Iranian nuclear facilities – widely suspected to be an Israeli or even U.S. covert action – was a model of a responsibly conducted cyber-attack, said the top lawyer for the U.S. military’s Cyber Command, Air Force Col. Gary Brown. By contrast, the Chinese stance, which holds that the international law of armed conflict does not apply in cyberspace, opens the door for indiscriminate online actions launched with less concern for collateral damage than was evident in Stuxnet, he warned, while a joint Russo-Chinese proposal for international collaboration on cyber-security could potentially threaten free speech.

Brown emphasized that his remarks represented his own opinion and that he was not speaking for the U.S. government, but they still open a window into the thinking of an influential official on the cutting edge of policymaking on cyber war.
