This book is an overview of the (at the time) current incidents linked to cyber infrastructure. It also tries to introduce classic philosophical concepts about the "cyberspace". Indeed, at the time of writing that book (2013), cyberwar was present in every mouth and especially in fearmongering terms such as "cyber 9-11" or "cyber Pearl Harbor" but lack conceptual understanding.

Before diving into the large number of examples, the author sets the base concepts for war (Clausewitz), espionage, sabotage and subversion. Reading this book almost 10 years later brings a lot of perspective and truth to the assumptions of the author. As a lot of them remained true, one can reflect about what cyberwar actually is. Cyberwar don't create "cyber deaths" and until now no known incidents lead to the direct deaths of humans (among others). Further conceptual work and time must pass before we grasp the specific nature of cyberwar.

The political concepts of this book are the most interesting part as the examples are today a bit dated and more recent one are well covered by books like "Sandworm" (2019) and subversion online has been extend studied in the past 10 years (from Castells to Coleman).

However, it seems that a lot of philosophical work is still needed to understand what "cyberwar" means in 2022. Is it a part of "real" war? Is it something totally different? What about cyber espionage and cyber sabotage?

The current war in Ukraine and its currently "missing cyberwar" (comparing it to Sandworm for example) does bring these questions into perspective. "Cyber war will not take place" remains a good read to everyone interested in those questions, although a lot of the examples seem outdated today they remain relevant (Aramco hack, Operation Aurora, APT1 etc.).
