From the article found on NextGov:
“At some point, we have to demonstrate the willingness to use it in national security. It doesn’t mean we attack somebody,” Cartwright said. “If we are attacked, we have to be able to say to somebody ‘I know who you are. I can figure it out. Even if I don’t know who you are --I will find you eventually, and if I do, then I will remain proportional in my response and timely, but I will respond.”Even such people as Leon Panetta, the current Secretary of Defense and former CIA Director, frequently warn that "the next Pearl Harbor" is likely to be a cyberstrike on our infrastructure systems (Gas, power, water, etc). How likely? Some say it's already happened more than once.
