In 2011, Pentagon officials took at least one step in this direction when they announced that any digital attack against the United States that took out portions of the electric grid or resulted in casualties would be considered an act of war and receive the appropriate response—even a kinetic military response, if the situation called for it, using “all necessary means.”53 In other words, as one military official put it, “If you shut down our power grid, maybe we will put a missile down one of your smokestacks.”
Yes , though the real trick is identifying the actor without possibility that it was someone else posing as the supposed actor. So much opportunity for framing another nation or group to provoke a conventional warfare response.
