Friendly Fire, in this instance, refers not merely to a tragic error of war, witnessed at least as much in Vietnam as in American wars before and since - it also refers, metaphorically, to America's war with itself during the Vietnam years. Starting from this point, Kinney's book considers the concept of 'friendly fire' from multiple vantage points, and portrays the Vietnam age as a crucible where America's cohesive image of itself shattered - pitting soldiers against superiors, doves against hawks, feminism against patriarchy, racial fear against racial tolerance. Through the use of extensive evidence from the film and popular fiction of Vietnam (e.g Kovic's Born on the Fourth of July, Didion's Democracy, O'Brien's Going After Cacciato, Rabe's Sticks and Stones and Streamers), Kinney draws a powerful picture of a nation politically, culturally, and socially divided, and a war that has been memorialized as a contested site for art, media, politics, and ideology.
