No shots were fired in this war, and there are unlikely to be any casualties. Most academic studies of war set a threshold of at least 1,000 battlefield casualties for the conflict to count as a war. But the Sony hack isn't conventional war. It is, instead, cyberwar, a newer and stranger beast. In 2013, the Director of National Intelligence published a report identifying cyber attacks as America's top security threat. While that sounds scary, it's mostly good news. Past number one threats included nuclear stand-offs and terrorism, both of which have actual body counts. Cyberwar is, so far, mostly sabotage and information theft.
