But now, somehow, it seems that war may no longer seem so terrible.

How has this come to pass? The culprit is the bits and bytes that are the principal weapons of cyberwar. It is now possible to intervene swiftly and secretly anywhere in the world, riding the rails of the global information infrastructure to strike at one's enemies. Such attacks can be mounted with little risk of discovery, as the veil of anonymity that cloaks the virtual domain is hard to pierce. And even when "outed," a lack of convincing forensic evidence to finger the perpetrator makes heated denials hard to disprove.
