- Abstract:
- This paper focuses on countries under extended nuclear deterrence arrangements, or ‘umbrella’ states. The paper explores the ways in which umbrella states both in the Asia-Pacific region and in Europe have supported prevailing nuclear deterrence practices or distanced themselves from such practices. While there is a tendency for these countries to side with their nuclear-armed patron on matters related to nuclear weapons and nuclear disarmament norms, at times they have taken steps away from the allied mainstream position by advocating for anti-nuclear weapon policies. As long as extended deterrence has a nuclear dimension, allies will need to balance between normative pressures to support nuclear disarmament and alliance commitments that require at least passive support for nuclear deterrence practices.
