By Josias Bruderer. The US interference in the war between Israel and Iran has hardly shed any light on the blurred situation, let alone made the region safer. Contradictory and divergent reports on the extent of the destruction, remaining facilities and consequences emphasize the lack of clarity. Malte Göttsche, a principal investigators of VeSPoTec and Professor for Peace Research in Natural Sciences at PRIF (Leibniz-Institut für Friedens- und Konfliktforschung), assesses the situation.

By Neslihan Yanikömer. In an increasingly complex geopolitical landscape, achieving nuclear disarmament requires more than political will—it demands a robust, realistic framework for implementation and compliance. To explore what such a framework might entail, the VeSPoTec research consortium conducted a 1.5-day tabletop exercise on April 10–11, 2025, focused on irreversibility and compliance within a regional disarmament scenario.

This four-day event was organized as part of VeSPoTec ("Verification in a Complex and Unpredictable World: Social, Political, and Technical Processes"), a research consortium funded by the German Federal Ministry of Education and Research (BMBF), in collaboration with the University of Duisburg-Essen.

By Julian Schäfer. Over the past year, the VeSPoTec project has been actively involved in various events and initiatives. These activities have allowed us to share our research, collaborate with experts, and contribute to discussions on nuclear disarmament and nuclear verification. This recap provides an overview of the key events and achievements from the past year.

By René Geiser. China’s nuclear expansion and global nuclear order The expansion of China's nuclear arsenal has increased significantly in recent years. Forecasts by the US Department of Defence assume that China could have over 1,000 operational nuclear warheads by 2030. This represents a significant expansion compared to the ‘minimum nuclear deterrent’ that China has traditionally pursued. While China used to strive for a small but survivable nuclear arsenal, the current modernization signals a possible shift in the balance of power. Through the introduction of new delivery systems, more mobile launchers and the construction of intercontinental silos, China is strengthening its nuclear presence in a way that challenges US nuclear dominance in particular.

By Neslihan Yanikömer and Irmgard Niemeyer. On September 18, members of the research consortium VeSPoTec, Dr. Irmgard Niemeyer and Dr. Neslihan Yanikömer, hold a side event on hosted by Germany during the 68th IAEA General Conference (September 16–20, 2024). The event, titled “Navigating Crisis Scenarios in Safeguards Implementation,” assembled an expert panel to discuss strengthening IAEA safeguards in the face of crises such as armed conflicts, natural disasters, and pandemics. Nearly 50 attendees participated in this discussion on a pressing global issue.
