Who cares if the US Air Force prefers to call cyberspace a "domain", as in a new battlespace on par with air, land and sea?
It's not an insignificant question, and cheers to Bettina Chavanne at the Ares blog for enlightening us with an email from an anonymous US Air Force officer who's not afraid to commit the professional military sin of doctrinal heresy.
The USAF position that cyberspace must be defended like national territory is worthy of a robust debate, and Bettina's post is as good a place as any to start the conversation. Here's an excerpt, but go read the full email:
