NATO Nuclear Policy Symposium Concludes in Istanbul with 150 Experts Discussing Deterrence

NATO’s annual Nuclear Policy Symposium concluded in Istanbul on April 22, 2026, bringing together 150 experts from across the Alliance to exchange views on nuclear policy and nuclear deterrence. The symposium occurred ahead of the Ankara Summit, where experts from Allied countries discussed geopolitical shifts and the nuclear landscape, the implications for arms control, disarmament and non-proliferation, as well as the full spectrum of issues relevant to NATO’s nuclear deterrence and its continuous adaptation.

NATO Secretary General Mark Rutte delivered a virtual address at the symposium.

Rutte thanked Türkiye for hosting the event and praised Türkiye’s strong contributions to Allied security, including its defence investments across all domains. He stated that Türkiye’s defence industry continues to innovate and grow. “In times of great instability, as the importance of nuclear deterrence grows, we must ensure NATO’s nuclear deterrence remains credible, safe, secure and effective,” Rutte said.

He added that as Allies approach the Ankara Summit, crucial decisions will need to be made, including how NATO’s nuclear posture will need to further adapt to the deteriorating security environment. The Nuclear Policy Symposium has been held annually since 1992, according to NATO.
