The geopolitical implications of the Israel-US-Iran war

Barry Buzan's work on regional security complexes introduces a framework for understanding how security dynamics are clustered regionally rather than globally. He argues that states' security interdependence is often strongest with their immediate neighbors, forming distinct complexes with their own patterns and drivers of conflict and cooperation. The approach helps explain why regional dynamics can diverge from global power politics and why local processes matter for conflict escalation and mitigation. Buzan applies the concept across different world regions, illustrating how historical, cultural, and geographic factors shape security relations. His analysis has become central in International Relations for studying sub-system level security dynamics.
