ABSTRACT

Deglobalization pressures are increasingly reshaping the governance ecology of international security by tightening geopolitical blocs, politicizing interdependence, and fragmenting institutional authority across issue areas. This article conceptualizes international security governance in the deglobalization era as a problem of cross domain risk diffusion under conditions of intensified great power competition, where security threats and disruptions propagate through supply chains, finance, information infrastructure, and regional security complexes, while institutional responses struggle to maintain coherence, legitimacy, and enforceability. Building on risk governance and global security governance perspectives, the study develops an analytical framework that links three mechanisms of risk diffusion, namely interdependence channel transmission, domain coupling through technology and infrastructure, and strategic amplification through competitive statecraft, to three families of institutional response, namely multilateral orchestration, minilateral security cooperation, and hybrid governance arrangements. The argument is illustrated through comparative discussions of the Indo Pacific maritime cyber domain, crisis governance in global health emergencies, proliferation risks in the Middle East and North Africa, and emerging regional theatres such as the Arctic.
