"The spread of digital technology comes at a cost: it exposes armies and societies to digital attack," says The Economist, which thinks cyberspace must be treated as a theater of war. "The world needs cyberarms-control as well as cyber- deterrence. America has until recently resisted weapons treaties for cyberspace for fear that they could lead to rigid global regulation of the internet, undermining the dominance of American internet companies, stifling innovation and restricting the openness that underpins the net. Perhaps America also fears that its own cyberwar effort has the most to lose if its well-regarded cyberspies and cyber-warriors are reined in. Such thinking at last shows signs of changing, and a good thing too."
