Bittere rivalen belicht de essentiële geschiedenis - en het diepgaande rimpeleffect - van de machtsstrijd tussen Iran en Saoedi-Arabië. Het is gebaseerd op tientallen interviews met politieke, religieuze en militaire leiders, militiecommandanten, diplomaten en beleidsexperts, en schetst het meest uitgebreide beeld van de Amerikaanse televisie van een vete die het Midden-Oosten heeft hervormd.
