If this is a justified belief rather than a faith-based belief, you'll need to offer a refutation of Thomas Rid's "Cyber War Will Not Take Place", which holds that cyber-war is contradictory because acts of cyber-war do not fulfill the definition of acts of war: http://www.tandfonline.com/doi/pdf/10.1080/01402390.2011.608...

Ok, so cyber-warfare is a shitty word. I know that, but people understand what it refers to, which is why I used it.

Would you be happier if I said I expect cyber-sabotage, cyber-espionage, and cyber-subversion to be important parts of future conflicts?
