Navigating the Persian Gulf Security Complex: Saudi-Iran Rapprochement in an Era of Great Power Competition.

The Gulf region, an epicenter of intricate security dynamics, is marked by a plethora of actors and interests contending for dominance and stability. The Saudi-Iranian discord, a salient axis of tension, echoes beyond their bilateral relations, shaping the security architecture of the wider region. This study ventures into the convoluted Middle East Regional Security Complex (MERSC), with a particular emphasis on the Gulf, exploring the impacts of Saudi-Iranian rapprochement and presenting a sophisticated analysis against the canvas of the prevailing great power competition. Adopting a strategic perspective, the research dissects the intricate interactions of regional units, concurrently addressing the pivotal shifts in power dynamics underscored by the waning US clout and the rising prominence of China. The Regional Security Complex Theory (RSCT) is the analytical prism through which the study elucidates the evolving geopolitical landscape, offering valuable insights into the potential and impediments of engendering stability in this significant geopolitical nexus.
