It is great pleasure to write an introduction to this roundtable on Cyber War Versus Cyber Realities by Brando Valeriano and Ryan Maness. This is an important book, one of the very few that addresses the new cyber age from a theoretical as well as an empirical perspective. The reviews are written by notable scholars who are well versed on relevant substance, theory, and methods. Each brings an important perspective to bear on the challenges at hand. And each provides important critiques in highly constructive terms. This book is also somewhat controversial in its purpose as well as its theoretical views, analysis, and execution.
