Abstract
Introduction
Global geopolitical transformations, particularly the gradual transition in the international distribution of power and the redefinition of the roles of extra-regional actors such as the United States and China, have placed the Middle East regional security complex on the verge of a structural transformation. This study seeks to analyze the determinants shaping the future regional security order and to explain the future position of Iranian diplomacy within the emerging regional power structure. The central concern of the research is to explain how key variables are reshaping the regional power structure and through what mechanisms these transformations affect the future position of Iranian diplomacy. The main hypothesis argues that although traditional factors such as military capabilities remain important, variables including economic resilience, access to strategic technologies, and the ability to adapt to emerging structural transformations will play an increasingly decisive role in shaping diplomatic influence and regional standing.
Research Question
How do the key variables reshape the power structure in the Middle East, and through what mechanisms do these transformations affect the future position of Iranian diplomacy?
Literature Review
The existing literature falls primarily into three categories: (a) macro-level approaches to power transition (e.g., Tammen & Kugler) that often overlook the agency of regional actors; (b) regional security complex theory (Buzan & Wæver), which provides a valuable analytical framework but does not sufficiently explain the distinctive characteristics and strategic behavior of individual political units; and (c) event-driven analyses (e.g., Danahar) that lack the theoretical depth required to explain the mechanisms underlying regional transformation. The present study seeks to bridge this gap through an integrated multi-level approach that combines structural and regional variables within a single analytical framework.
Methodology
The study adopts a qualitative methodology based on analytical qualitative content analysis within the framework of Regional Security Complex Theory. In this framework, the Middle East is examined as a regional security complex whose structure has historically been influenced by external ordering powers and is currently undergoing significant transformation as a result of shifting global and regional balances. Accordingly, the study analyzes a set of macro-level and regional-level variables to identify the principal drivers shaping the future regional power structure and their implications for Iranian diplomacy.
Findings
The findings indicate that at the macro level, two major trends are transforming the regional power structure: the gradual reduction of United States strategic concentration on the Middle East and the growing economic and technological influence of China. Within this broader structural context, recent American policies toward Iran can also be understood as part of a larger strategic effort to reallocate resources and attention toward competition with China.
At the regional level, six key variables are identified as the principal determinants of the future security environment: tensions between Iran and the Israeli regime; Iran’s nuclear and missile capabilities; the trajectory of Iran–Saudi Arabia relations; the continuation of the Abraham Accords and their impact on regional alignments; China's growing influence in technological and infrastructural domains; and changing priorities in United States foreign policy. The findings demonstrate that the Middle East is entering a prolonged period of turbulent transition in which economy and technology increasingly become central components of security and power competition, thereby reshaping regional patterns of rivalry and cooperation.
Conclusion
The study concludes that the future position of Iranian diplomacy within the emerging regional order depends largely on Iran’s ability to manage the aforementioned variables. While strategic assets such as missile deterrence and regional influence remain important, they are insufficient on their own to secure a favorable diplomatic position. More decisive factors include the ability to establish economic stability, diversify the domestic economy, attract and develop strategic technologies, pursue active diplomacy aimed at reducing tensions—particularly with Saudi Arabia—and strengthen regional coalition-building capacities. These factors are directly linked to the effectiveness and influence of Iranian diplomacy in the evolving regional environment. In the emerging security order, economic efficiency and the capacity to generate welfare are becoming increasingly important sources of domestic legitimacy and external influence, while hard-power instruments alone are no longer sufficient to sustain diplomatic standing or regional influence.
