This book explores the relationship between the state and war within the context of seismic technological change. As we experience a fourth industrial revolution, technology already exerts a huge impact on the character of war and military strategies in the form of drones and other types of ‘remote’ warfare. However, technological developments are not confined to the defence sector, and the diffusion of military technology inevitably also affects the wider economy and society. This book investigates these possible developments and speculates on their ramifications for the future. Through its analysis, the book questions what will happen to war and the state and whether we will reach a point where war leads to the unmaking of the state itself.
