The scope of this book may in fact be too vast for many readers -- the information, observations, research, and studied opinions compiled here require slow and incremental examination.
As the world population concentrates rapidly into urban areas, there are corresponding escalations in how military doctrine and war planning incorporates urban zones, in both the "first" and "third" worlds. Involved in this are perceptions, some of them quite historic, about what cities are, and to do about the poorer masses who live there and protect the more privileged citizens.
When cities are incorporated into military planning, when terrorists attack cities, when cities are military targets, where is the line between civilian space and military space?
What is going on when military technology, particularly "non-lethal" technology, is deployed for the purpose of controlling civilian populations, at anti-capitalist demonstrations for example?
This work also examines battle-simulations as entertainment (video games, paintball, etc.), "garrison tourism," and mock cities used for military exercises.
And commendably, Graham does include critique of economic systems (mainly capitalism), noting the connection between economic relations and violence.
