Russia’s invasion of Ukraine increases nuclear risks and represents a major setback for multilateral nuclear non-proliferation and disarmament diplomacy. To mitigate the risk of nuclear escalation, the P5 must demonstrate to the international community that they stand behind their joint affirmation that “a nuclear war cannot be won and must never be fought.”
The recent P5 affirmation that “a nuclear war cannot be won and must never be fought” as well as the incorporation of strategic risk reduction into the nuclear doctrines and dialogues working group are impactful and are welcome first measures. The P5 must now build on this momentum to discuss a substantive programme of work which must will lead to the implementation of concrete risk reduction measures within the eleventh review cycle.
On the eve of the tenth Nuclear Non-Proliferation Treaty (NPT) review conference, the P5 should establish a regular, open-ended and sustained dialogue process on strategic risk reduction to improve the international security environment.
