Not a post, but my response to “How Would We Know if a Cyber War Started?“:
Well one way to answer the title’s question is this: One can view Cyber War as a highly computerized evolved form of the Cold War. It has begun years ago, it is being conducted right now by various players (state and non-state actors) and will continue in the future. So it has already begun.
Other than that, I’m with @JeffreyCarr on the article’s relevance.
