Articulating the logic of nuclear-sharing

Alexander Mattelaer

NATO’s nuclear-sharing arrangements often get bad press. This is remarkable given the fact that they have demonstrably contributed to (a) countering the proliferation of nuclear arsenals in Europe, (b) fostering alliance cohesion by giving non-nuclear weapon states a voice on the nuclear posture of the alliance, and (c) making nuclear deterrence more effective militarily by offering a wider array of force options. When the relative merits of extended nuclear deterrence are unknown, public support thereof is likely to suffer. In order to enrich the debate about NATO’s nuclear policy, this Security Policy Brief articulates the threefold logic of nuclear-sharing.
