In a riveting narrative based on accounts of her interactions with Saudi and Iranian politicians and rich archival material, a leading scholar on the Middle East unravels the mysteries of a contentious relationship. This seasoned observer of political and diplomatic worlds shatters the myth of the inevitability of sectarian conflict and that the diplomacy between Saudi Arabia and Iran is exhausted. Instead, Banafsheh Keynoush argues that it has yet to be explored, by recasting the partnership from a US-centered point of view to one based on how Saudi Arabia and Iran see their roles. Who is to blame and how to fix it is part of this penetrating historic account which captivates readers through accurate, non-sensational, and objective analysis. Keynoush recounts it all: the fears, misunderstandings, prejudices, and ambitions that have hobbled efforts to build a lasting partnership, creating a work that is important to both the expert and the layperson.
