Studying the behavior of regional actors leads to a deeper understanding of regional policies and powers. In the Middle East region, several countries hold a superior position compared to others due to their geopolitical location and weight. Iran, Turkey, and Saudi Arabia are among the prominent actors in the Middle East, whose decisions, given their geopolitical power and influence, significantly impact the entire region. A precise and realistic understanding of the shared geopolitical and geographical capacities among these countries can provide a foundation for enhancing convergence, managing disputes, and achieving sustainable peace in the Middle East. This research seeks to answer the question of how, through understanding the geopolitical components of the region, it is possible to achieve de-escalation and establish sustainable peace among the three geopolitical powers Iran, Turkey, and Saudi Arabia in the Middle East? The findings indicate that by emphasizing the foundations of the region’s shared geography, regional geopolitics, geo-economic cooperation, and a peace-oriented geopolitical approach, the conditions for de-escalation and the strengthening of peacebuilding can be fostered in the Middle East (Iran, Turkey, and Saudi Arabia).
