№ 15 (22), 2025. Nuclear Sharing and Strategic Stability: Lessons from Past and Present

November 25, 2025

Nothing New Under the Sun

The Soviet Union did not openly criticize nuclear sharing after entry into force of the NPT. Neither did the Russian Federation in the 1990s-2000s. However, in 2014 the Russian approach to this question changed, and Russia started to speak out against NATO nuclear sharing arrangements by pointing out that such arrangements violate Articles I and II of the NPT.

Semenov, Sergey D.

Questions surrounding the legal and political foundations of nuclear-sharing arrangements have regained visibility, as these practices are increasingly examined within the broader context of contemporary strategic stability discussions and the evolving landscape of arms-control regimes.

We would like to recall the chapter authored by Mr. Nikita Degtyarev and Mr. Sergey Semenov, “Nuclear Sharing Arrangements: Military-Technical Aspects and Controversies,” which was first published in PIR Center’s collective monograph “Russia-U.S. Nuclear Nonproliferation Dialogue: Lessons Learned and Road Ahead” (2021). The authors offer an in-depth overview of the evolution of nuclear-sharing practices and the factors that have brought this issue back into current strategic stability discussions.
