The history of Australia’s attempts to acquire a nuclear deterrent capacity transpired both within and outside the spirit of the international Atoms for Peace program. While this article reprises a range of scholarship to provide a historical overview, it provides for the first time a level of detail not previously disclosed concerning the mechanisms, costs, and approaches of successive Australian governments in their estimations of obtaining an indigenous nuclear capacity. One such revelation concerns Australia’s “back-door” acquisition option by hosting Peaceful Nuclear Explosions, ostensibly for civil engineering purposes, and their provision of preassembled thermonuclear technologies and devices. During the international and bilateral negotiations for the Nuclear Non-Proliferation Treaty, Australia was deeply concerned that the draft Treaty would limit or deny this option.

How would North Korea’s development of the capability to target the United States with nuclear weapons influence its foreign policy? I argue that it would cause more dangerous crises than those of the last decade, and predict that these crises would eventually cause Kim Jong Un and his senior military associates to experience fear of imminent nuclear war or conventional regime change. I show that the effect of such fear would depend on whether or not Kim believes that he has control over the occurrence of these events. I argue that if he experiences fear and believes that he has some control over whether these extreme events actually happen, he will moderate his nuclear threats and behave more like other experienced nuclear powers. But if he experiences fear and believes that he has no control, he will likely pursue policies that could cause nuclear war. I use this insight to prescribe and proscribe policies for Washington, Seoul and the regional community.
