John Arquilla and David Ronfeldt’s distinction between Netwar and Cyberwar?

Netwar refers to information-related conflict at a grand level between nations or societies. It means trying to disrupt, damage, or modify what a target population “knows” or thinks it knows about itself and the world around it. A netwar may focus on public or elite opinion, or both. It may involve public diplomacy measures, propaganda and psychological campaigns, political and cultural subversion, deception of or interference with local media, infiltration of computer networks and databases, and efforts to promote a dissident or opposition movements across computer networks.
cyberwar may raise broad issues of military organization and doctrine, as well as strategy, tactics, and weapons design. It may be applicable in low- and high-intensity conflicts, in conventional and non-conventional environments, and for defensive or offensive purposes.
