Security cooperation in the Pacific Islands: architecture, complex, community, or something else?

In the 2018 Boe Declaration, Pacific Islands Forum leaders recognized that the region is facing 'an increasingly complex regional security environment' and committed to 'strengthening the existing regional security architecture'. Given uncertainty about the existence and nature of this architecture, we address the question: is there a security architecture in the region, or does security cooperation take a different shape? We find that security cooperation in the Pacific Islands does not constitute a security architecture, as there is no 'overarching, coherent and comprehensive security structure for a geographically-defined area'. We also find that the region is neither a security complex nor a community, due to the extensive involvement of metropolitan powers and external partners.
