A new book, "Digital Soldiers," by James F. Dunnigan, emphasizes that information warfare -- deceiving the enemy -- is as old as war, and that the PR-driven media today work closely with the warfighting industry to protect their mutually lucrative markets. The latest GAK PR campaign fits this. Dunnigan also makes hash of the recent opportunistic "infowar" PR, along with adept grinding of the vast, corrupt high-tech defense industry worldwide, led by the US war-prognosticating PR-media-policy lizards. As he says, bad news is always good news for the Hearsts and Rasputins (Responsible Personages), for the liars of brimstone religion, for all the terrifying doomsayers peddling trust-my-god: me, now tithe or be taxed. Dunnigan's sermon: stop the pork, then there will be plenty of resources to deal with the rest of society's ills. Otherwise, peace, real or vitural, is war, sustained barbarity camouflaged by self-interested civility -- the peacefighting, ticket-punching officer, er, journalist, class.
