The French nuclear deterrent is the one that is most often compared to the UK’s nuclear forces. While there are similarities in terms of policy, posture and size, there are also significant differences in terms of industrial support and cost. In contrast to the UK all of the major political parties in France support an independent nuclear deterrent, and domestic support is high. This paper examines the French nuclear deterrent in greater detail. It is also part of a wider Library briefing series on nuclear weapons.
