Backchannel Non-Proliferation: Militarily Non-Aligned States and Nuclear Diplomacy

This chapter appears in Nuclear Non-Proliferation in International Law — Volume VI.

What roles can small militarily non-aligned States play in nuclear non-proliferation diplomacy with actual or suspected proliferators? And how might international law shape such contributions? Current literature identifying effective approaches to nuclear non-proliferation and rollback is somewhat one-dimensional, emphasising the behaviour of great powers and international organisations. By contrast, this chapter analyses activities militarily non-aligned States may undertake supporting negotiations in accordance with international legal norms and institutions. More specifically, it explores Swedish and Swiss initiatives in the early 2000s, a period of growing tensions over the Iranian and North Korean nuclear programmes. Drawing upon resources including unpublished elite interviews, the chapter offers new insights into theoretical backchannel non-proliferation mechanisms. It complements existing literature on nuclear proliferation by offering a fuller account of diplomatic negotiations. Ongoing crises suggest many future challenges to the non-proliferation regime will emerge, and militarily non-aligned States may hold one of the few keys to facilitating dialogue. International law can both compel these States to act and provide them with influential—but often-overlooked—non-proliferation roles. Indeed, reconsidering dominant narratives about ‘players’ involved in nuclear diplomacy may provide new avenues for policy-making and theorising aimed at preventing the spread of nuclear weapons.
