This chapter provides a structured analysis of US-Japan-Australia strategic minilateralism under the broad mantle of the Trilateral Strategic Dialogue (TSD). It applies the analytical framework from Chapter 4 of this book to assess its strengths and weaknesses through a traversal of its design, functions, and solvency features. This reveals a strong alignment that is developing a plausible collective deterrent posture and the capabilities to respond to a regional contingency.
