Experts discuss the state of the global nuclear order.

The global nuclear order is under increasing strain. North Korea has expanded its arsenal, the state of Iran’s programme is unclear even after recent strikes, and the risk of nuclear escalation in the Ukraine-Russia war remains high. At the same time, the P5 have made little progress on disarmament, leaving the Non-Proliferation Treaty (NPT) under mounting pressure ahead of its 2026 Review Conference. Nuclear-armed India and Pakistan remain in a fragile state, with tensions between the two resurfacing. Both the US and Russia have walked away from existing agreements and treaties designed to limit expansions of arsenals. Nuclear non-proliferation is faltering.

Moreover, the notion of acquiring nuclear weapons is gaining traction in South Korea, Japan, Saudi Arabia, and even parts of Europe. As reliability and security of America’s nuclear umbrella, in place to protect allies and deter threats, retreats under the Trump administrations ‘America First’ strategy, more countries are looking at options to build out their own nuclear deterrence.

This discussion explores the state of the non-proliferation regime and the urgent need for leadership in a rapidly shifting security environment. Key questions include:

  • Can leadership on non-proliferation be found in a fragmented geopolitical order? Or will a new structure take shape?
  • How can trust in international cooperation be rebuilt?
  • Can the NPT adapt to deter new aspirants while holding nuclear powers accountable?
  • What are the prospects of more states acquiring nuclear weapons?
  • What would renewed arms race mean for global security?
