In time of conflict, sides are drawn and groups identify themselves and others through symbols and signs. Signs can predict, represent, support, or protest war; their association to meaning may be obvious, unequivocal, or ambiguous, different according to co-opters or viewers, or yet hidden, unconscious. It is therefore vital to apprehend and understand their various meanings which is the aim of this collection of essays through the analysis of visual and written signs, relating to Vietnam, 9/11 and the now Iraq War, in the US or abroad, such as the US flag, ribbons, car-stickers, cartoons, movies, the media and presidential war rhetoric.
