These recent events demonstrate how quickly the nation\u2019s escalating cyberbattles have outpaced the rush to find a deterrent, something equivalent to the cold-war-era strategy of threatening nuclear retaliation.<\/p>\n
So far, despite millions of dollars spent on studies, that quest has failed. Last week, Secretary of State Hillary Rodham Clinton made the most comprehensive effort yet to warn potential adversaries that cyberattacks would not be ignored, drawing on the language of nuclear deterrence.<\/p>\n
\u201cStates, terrorists and those who would act as their proxies must know that the United States will protect our networks,\u201d\u009d she declared in a speech on Thursday that drew an angry response from Beijing. \u201cThose who disrupt the free flow of information in our society or any other pose a threat to our economy, our government and our civil society.\u201d\u009d<\/p>\n
But Mrs. Clinton did not say how the United States would respond, beyond suggesting that countries that knowingly permit cyberattacks to be launched from their territories would suffer damage to their reputations, and could be frozen out of the global economy.<\/p>\n
