West Asia is a complex geographical and geopolitical setting characterized by identity diversity, geopolitical rivalries among powers, and extra-regional interventions. Iran, in turn, shapes its relations with regional countries under the influence of the consequences arising from this environment. Drawing on Cantori and Spiegel’s theory, this article examines the geopolitical variables affecting the dynamics of convergence and divergence in Iran’s relations within the regional system of West Asia. Accordingly, the main variables of the model including (cohesion, the nature of communications, the level of power, the structure of relations, and the role of the intervening system, represented by the United States), are analyzed. Employing an explanatory-analytical approach, the findings indicate that the region is trapped in a structural pattern of divergence. Although Iran maintains religious and political ties with certain countries, ethnic and linguistic diversity, differences in political systems, non-complementary economic structures, divergent interests, and differing memberships in regional organizations hinder sustainable convergence. Furthermore, competing narratives, underdeveloped communication infrastructure, and the strengthening of rival corridors, together with an asymmetrical multipolar distribution of power, a limited regional relationship structure, and Iran’s lack of formal allies, have reinforced regional divergence alongside increasing U.S. intervention. The study concludes that these divergent variables do not operate independently; rather, they mutually reinforce and reproduce one another. To mitigate this situation, the development of interdependence between regional security and shared economic interests with neighboring countries, combined with strategic balancing through cooperation with Eastern powers, is considered a realistic approach to moderating the effects of U.S. intervention. Finally, the study also emphasizes the need to employ data-driven approaches for the continuous assessment of the regional balance of power.
