Abstract
As a doctrinal matter, the Pentagon has formally recognized cyberspace as a new domain of
warfare. It has become just as critical to military operations as land, sea, air, and space.†These
words, written by Deputy Secretary of Defense William Lynn last fall in Foreign Affairs, cemented the
status of cyberspace as a domain of warfare like all others, and coincided nicely with US Cyber
Command reaching its full operational capacity.
