The Legacy of the Shatt al-Arab Waterway Dispute in Post-2003 Iran-Iraq Relations
Bibliographic record
Abstract
The Shatt al-Arab waterway, a historically contested boundary between Iran and Iraq, has long been a focal point of regional tension, contributing to the outbreak of the 1980–1988 Iran-Iraq War and shaping bilateral relations throughout the 20 th century. This article aims to examine the legacy of the Shatt al-Arab dispute in the post-2003 period, following the fall of Saddam Hussein. It investigates how the historical tensions over territorial sovereignty, navigation rights, and treaty obligations have persisted or evolved within the broader framework of Iran-Iraq relations under new political realities. The findings suggest that while the Shatt al-Arab has not re-emerged as a flashpoint for open conflict, it remains a latent source of mistrust and strategic calculation. Post-2003 dynamics have been characterized by fluctuating cooperation and competition, shaped by broader sectarian alignments, political instability in Iraq, and Iran's growing regional influence. Efforts at diplomatic normalization—such as joint border commissions and navigation protocols—have been undermined by security concerns and unresolved treaty legacies, particularly regarding the 1975 Algiers Agreement. Utilizing a qualitative methodology, this study draws upon primary sources such as diplomatic statements, official agreements, and UN records, alongside secondary sources including scholarly literature and policy analyses. The article employs a historical-institutionalist approach to trace the continuity and transformation of bilateral norms and practices related to the waterway. The article concludes that the ‘Shatt al-Arab’ dispute continues to act as both a symbol of unresolved historical grievances and a potential site for future diplomatic engagement. Its legacy underscores the need for institutionalized mechanisms of conflict resolution and cross-border environmental governance in the Iran-Iraq relationship.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
