As someone who has spent most of his life behind the closed doors to which he refers, and who is now responsible for drawing the Australian public into debate on foreign and defence issues, he knows better than most the communication challenges that governments face. When it comes to engaging the public on the US alliance, and its nuclear dimension in particular, these challenges are complex and growing. This chapter explores these challenges, some of which are unique to Australia. It argues that Canberra's decision-makers have reached a critical juncture in their attempts to reconcile Australian approaches to nuclear deterrence and disarmament: policies that have been problematic for years are threatening to backfire, the result of declining legitimacy, domestic political missteps and events that are beyond Canberra's control.
