The Influence of Member States Domestic Determinants on the Implementation of Pillar Two of the 2021 Australia - UK - U.S. Trilateral Security Partnership (AUKUS)

Abstract

This article provides insight into how distinct domestic determinants of AUKUS Member Countries may influence the implementation of Pillar Two of AUKUS. By utilising qualitative research methods, this article would like to provide a preliminary analysis of how the domestic determinants play an equally pivotal role in the effective implementation of pillar two. In particular, how and to what extent do these domestic determinants influence Pillar Two of AUKUS, centering on integrating advanced military capabilities. This article has three primary findings. First, the three-member states' domestic determinants are generally stable, regardless of their challenges. Second, domestic determinants are independent variables that influence the implementation of pillar two, which include the level of integration of military capabilities, progress, stability, and sustainability of this partnership. Third, the authors discover that pillar two can potentially contribute to a free and open Indo-Pacific region through integrated deterrence, defence and defence industrial base, and cutting-edge science and technology innovation.
