there'd better be such a thing as "cyberwar"

Because we've set up the bureaucracy for it. Laugh! as the people responsible for the new US Cyber Command try to work out what it's for. As far as I can see, it duplicates all or part of NSA, DISA, CIA, DHS, NIST, and the services' signals commands and electronics materiel agencies. It is true that IT is a little like the famous crack about economics - a science so wont to usurp all others - but this is ridiculous. Apparently we're getting one too. Oh joy. Fortunately it's described as a "coordinator", a traditional British term for someone with no power or budget, so it can't do too much damage.
