The military potential of nanotechnology was anticipated by its proponents from the early stages of its development, and explicit programmes for this purpose are now well established. However, the impact of nanotechnology on arms control is very unlikely to be merely additive. Instead, it threatens to undermine the arms control paradigm, for reasons explored in this paper. These include the place of nanoscience and nanotechnology as the principal enablers of technological convergence; the extension from dual-use to multiple-use dilemmas arising from new materials and processes, and their integration into economic development and competitiveness; low entry-level infrastructural requirements (already a feature of biotechnology); and a blurring of the distinction between offensive arms and capabilities likely to be viewed as threatening.

<p>A number of puzzles exist regarding the role of domestic politics in the likelihood of international conflict. In particular, the sources of incomplete information remain under-theorized and the microfoundations deficient. This study will examine the role that the unity of the government and the views of the government towards the use of force play in the targeting of states. The theory presented argues that divided dovish governments are particularly likely to suffer from military challenges. In particular, divided governments have difficulty signaling their intentions, taking decisive action, and may appear weak. The theory will be tested on a new dataset created by the author that examines the theory in the context of international territorial disputes. A number of significant findings emerge from the data. First, divided governments are significantly more likely to face challenges and increasing government unity markedly decreases the likelihood of a challenge. Second, unified hawkish governments were far less likely to be the targets of challenges than divided dovish governments. Finally, the substantive impact of key variables was much greater than that of the control variables. The causal process postulated in the theory is examined in eight case studies, two for each of the four government types. These case studies show that government type not only impacts the signaling of democratic states but also influences the perceptions of potential challengers.</p> / Dissertation
