The word "wargames" might seem like a contradiction in terms. After all, the declaration "This is war" is meant to signal that things have turned deadly serious, that there is no more playing around.

Covering everything from chess to football, from Saving Private Ryan to American Sniper, and from Call of Duty to drone interfaces, War Games is an essential guide for anyone seeking to understand the militarization of American culture, offering a compact yet comprehensive look at how we play with images of war.
