This paper explores the contribution to understand the shifting MENA regional security order through the analytical lenses provided by hierarchy. It will do so by challenging the existing under-theorization of hierarchy in IR and the need to better understand different kinds of hierarchies and the ways in which they operate (Nexon 2009; Zarakol 2017). Through the examination of the changing MENA regional security order, this paper aims at mapping how power relations across different power dimensions have changed and are changing in light of the decline of US hegemony and the rise of regional and global actors. Hierarchical relations can namely change in degree of intensity but also qualitatively according to the resources and attributes they are predominantly based upon, be they of a material, in primis military and economic resources, or immaterial/symbolic nature, such as status. Secondly, it aims at bridging the gap between Regional IR and Global IR, on the one hand by systematically applying a refined notion of multiple hierarchies and heterarchies to the MENA regional security order. The author will attempt at further developing the research agenda of NHS, enriching it empirically and diachronically and will elaborate on how the Area IR and Global IR could more fruitfully remain into dialogue.
