This study seeks to elucidate the underlying factors driving Saudi Arabia’s shift from defense realism to offensive realism, focusing on MBS’s authoritarian rule and structural reforms aimed at minimizing bureaucratic hurdles in security and defense decision-making. The research examines the kingdom’s transition from conservative foreign policies to a more activist stance, illustrated by its support for Palestine and its adoption of non-conventional approaches to address emerging challenges. Adopting the John Scott document analysis model and utilizing secondary data, this study delves into the nuances of Saudi Arabia’s foreign policy shift under MBS’s leadership. It examines how his leadership style, combined with Vision 2030 goals and objectives, reflects a post-ideologically motivated transition that seeks to assert power and influence in the Middle East. The research explores the potential implications of this shift on regional security, including the Yemen civil war, balance of power realignment, and Saudi Arabia’s relationships with Western partners.
