Shane Harris talked about his November 14, 2009, National Journal cover story, "The Rise of Cyberwar." The story reveals new information about how the U.S. government has used cyber attacks against adversaries -- including the war in Iraq. He examined how cyberwar can be directed at commercial, economic, and military targets, and the risks that cyberwar entails. He also responded to telephone calls and electronic communications.
