To explain what Cyberwar is, we have to do a little exercise of imagination. Imagine a war without a battlefield, without troops deployed, without firearms, bombs, large-scale bloodshed. Imagine moving all hostilities into a large office, full of servers and monitors connected to the internet and controlled by a small handful of IT experts. ... The Cyberwar is already around us, with the world powers engaged in a new race to computer “armaments” and with the emergence of autonomous realities, disconnected from the national logic as the group Anonymous, the group of hacker’s activists that operates a cyber war parallel pursuing the purposes of ethics, morals and social commitment. Only history can decide the effects of information technology in the war, decreeing their real difference with the wars of the past.
