Iran War Aftershocks and Reshaping the Regional Order: Assessing the Current State of the Us–Iran War

Abstract

Purpose – The contemporary conflict between the United States and the Islamic Republic of Iran has evolved into one of the most consequential geopolitical rivalries of the twenty-first century, extending beyond conventional military confrontation to encompass proxy warfare, cyber operations, economic sanctions, maritime security, and nuclear diplomacy. This study examines the multidimensional nature of the US–Iran conflict and evaluates its implications for the evolving regional security order in the Middle East. Design/methodology/approach – This study adopts a qualitative research design based on documentary analysis. It integrates the perspectives of Offensive Realism, Balance of Power Theory, and Regional Security Complex Theory to analyze the strategic dynamics of the conflict. Data are drawn from scholarly literature, official government publications, think tank reports, policy documents, and reports from international organizations. The analysis employs thematic and comparative methods to examine the military, political, economic, diplomatic, and energy-security dimensions of the rivalry. Findings – The findings indicate that the US–Iran confrontation has accelerated the transition from a predominantly US-led regional security architecture toward a more fragmented and multipolar strategic environment. The conflict has intensified proxy competition, encouraged shifting regional alliances, and increased the involvement of external powers in Middle Eastern security affairs. While military deterrence has constrained direct interstate escalation, it has proven insufficient to address the structural drivers of the rivalry. Moreover, the expansion of proxy warfare has heightened risks to maritime security, global energy markets, nuclear non-proliferation, and regional governance, reinforcing geopolitical polarization across the region. Research implications/limitations – This study is limited to qualitative documentary analysis and does not incorporate quantitative conflict data or field-based evidence. Future research should employ longitudinal and empirical approaches to assess the long-term effectiveness of diplomatic initiatives, deterrence strategies, and regional security mechanisms. Originality/value – This study contributes to contemporary security and Middle Eastern studies by integrating multiple international relations theories to explain the transformation of the US–Iran rivalry within an evolving multipolar regional order. It argues that sustainable regional stability will require an inclusive security framework combining diplomacy, confidence-building measures, multilateral cooperation, and regional institutions capable of addressing both interstate competition and transnational security challenges.
