3/ Read the full report "The Geography of Nuclear Restraint in a Fragmenting Order: Nuclear-Weapon-Free Zones in an Unstable Security Environment" aurhored by @olamideDIY, @pirnavskaia, @valeriia_hesse here: opennuclear.org/en/open-nuclea… #NPT2026 #NWFZ #Nonproliferation

2/ONN’s new report shows NWFZs are more than legal tools: they support risk reduction, regional governance & restraint. But they face growing challenges: coordination gaps, capacity limits & structural weaknesses. @olamideDIY will draw on these insights to shape the discussion.

1/In a more unstable security environment, NWFZs remain key frameworks for nuclear restraint. Join today’s NWFZ NPT side event organised by Kazakhstan, UNIDIR, NTI & UNODA, moderated by ONN’s @olamideDIY. 🗓28 April | 13:15–14:30 EDT 📍UN, CR8 Register: forms.gle/K1BEjTSQnve9j1…

Tomorrow at 13:15 (CR.12), ELN + @NorwayMFA host a #2026RevCon side-event on strengthening the CTBT to safeguard the NPT. WATCH: @YGLNtweets member and @OpenNuclear Researcher @valeriia_hesse on why treaty-based norms matter for non-proliferation. In NYC? Join us-if not, watch & share! #NPTRevCon

I’m in NYC for the NPT RevCon. As the conference opens today, here’s a few things I’m watching out for 👇🏿 @OpenNuclear @PAX_sapiens

@Andreas_Persbo (ELN Senior Associate Fellow and Director, @OpenNuclear) reminds governments of the destabilising effects of nuclear weapons on global security.

Verification is central to nuclear disarmament. ONN Director @Andreas_Persbo participated in a recent workshop on disarmament verification by @UWConline, @vertic_org and African Nuclear Disarmament Verification Research and Innovation Hub. Learn more: opennuclear.org/en/open-nuclea…

🛰️Into satellite imagery & DPRK nuclear analysis?Hosted by @koreasociety, join @OpenNuclear's @sjladerman for a deep dive into DPRK’s nuclear programme, building on our recent DPRK project findings. 📅7 May, 5:30 PM EDT (in person + online) 🎟️Register: koreasociety.org/policy-and-cor…

🚀 If you want to learn more about High-Explosives Testing, read our primer: opennuclear.org/en/open-nuclea…

6/ ONN contributed specialised analysis on nuclear force structures, weaponisation capabilities and future trajectories. ONN contributions: opennuclear.org/en/open-nuclea…

🧵1/New #satimagery (DPRK & N5): mapped, analysed & brought together in StoryMaps. High-explosive testing is a critical yet often under-examined phase of nuclear weapons development, used to perfect non-nuclear "trigger" that compresses a nuclear core to achieve a chain reaction.
