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.â€ 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.
