Abstract :The Middle East has been a center of geopolitical struggle of, not only global powers, but also regional powers for two centuries. During the cold war the region had been divided between the Western and Eastern Blocs. Soon after Iran Revolution, the region became increasingly fragile, dissociated and violent because of domestic contention, sectarian conflict and foreign intervention. Both foreign and regional powers contended for geopolitical influence, especially in the wake of the Arab Spring uprisings in 2010s. In particular, Iran and Saudi Arabia’s competition dramatically has been changing geopolitics of the Middle East for the past couple of years. These struggles not only created failed states, conflict-afflicted areas, foreign intervention, economic destruction, humanitarian crises and provoked regional conflict, but also threatened peace and energy security in Gulf. This study examines how these geopolitical struggles in the Middle East have a vital impact on Gulf energy security. The argument of this study is that regional competition encourages instability, insecurity and hostile regional relations, and will additionally have a strong effect on global energy security, possibly inviting foreign players to the Gulf.
