z4ns4stu writes "Shane Harris of the National Journal describes how the US government plans to use, and has successfully used, cyber-warfare to disrupt the communications of insurgents in Iraq. 'In a 2008 article in Armed Forces Journal, Col. Charles Williamson III, a legal adviser for the Air Force Intelligence, Surveillance, and Reconnaissance Agency, proposed building a military "botnet," an army of centrally controlled computers to launch coordinated attacks on other machines. Williamson echoed a widely held concern among military officials that other nations are building up their cyber-forces more quickly. "America has no credible deterrent, and our adversaries prove it every day by attacking everywhere," he wrote. ... Responding to critics who say that by building up its own offensive power, the United States risks starting a new arms race, Williamson said, "We are in one, and we are losing."'"
