by The Royal United Services Institute
Global Security Briefing provides regular insights from leading international experts to help you make sense of the far-reaching changes affecting international security around the globe.

The Global Security Briefing channel is also host to a back-catalogue of episodes from the concluded RUSI podcasts 'Bridging the Oceans' and 'Mind the Gulf'.

Hosted by Veerle Nouwens, it explored what the Indo-Pacific is, where its limits lie, and what the fast-evolving defence and security issues are in this dynamic part of the world. Running from January to May 2022, the 'Mind the Gulf' Podcast Series explored how the Iranian nuclear programme – and international diplomatic efforts to prevent Iran from acquiring a nuclear weapon – interacts with regional security dynamics and the wider Middle East.

Radioactive Russian Drones - A Conversation with Vitaly Shevchenko
Vitaly Shevchenko of BBC Monitoring joins Natia Seskuria to explore the implications of a radiation warning found on a downed Russian drone. In April 2026, Ukrainian air defences shot down a modified Russian Geran-2 strike drone near Chernihiv, and investigators found a radiation warning label on the warhead, recording gamma readings far above natural background levels. Within hours the story spread internationally, often described as Russia deploying radioactive weapons or a dirty bomb, but neither description is accurate. Ukrainian investigators say the drone was carrying an R-60 air-to-air missile fitted with a depleted uranium fragmentation element, a modification Russia appears to be using to threaten Ukrainian aircraft intercepting the drones. The SBU has since documented further cases and opened a war crimes investigation. This episode looks at the weapon itself, how claims like this are verified, and what the incident reveals about information warfare and media monitoring in a fast-moving conflict. It also explores: What Ukrainian investigators found in the drone wreckage, and what the modification reveals about Russian production and stockpiles. How BBC Monitoring verifies claims of this kind, and what separates an established finding from an allegation. How radiation has featured in Russia-Ukraine information warfare since the 2022 'dirty bomb' claims. The social and cultural resonance of radiation stories in Ukraine and Russia. What responsible media monitoring looks like in an environment of overload and disinformation. Vitaly Shevchenko is Russia Editor at BBC Monitoring, where he has spent more than a decade analysing Russian and Ukrainian media. BBC Monitoring is a specialist service within the BBC World Service, delivering trusted analysis of open-source media around the world

Updating How We Think About Korean Peninsula Security
Philip Shetler-Jones is joined by Sanghun Seok and Dr Edward Howell to ask whether 'unification' and 'denuclearisation' are still the lenses through which we should view security on the Korean Peninsula. For decades, Korean Peninsula security discussions have been framed by North-South relations and nuclear proliferation considerations. But North Korea has dropped the goal of unification and refuses to discuss denuclearisation, while both Koreas have become more prominent players in security dynamics far beyond North-East Asia. This prominence ranges from North Korean troops fighting in Ukraine to South Korea's growing role as an arms supplier to Europe. This episode asks what should replace the old framing. The episode explores: North Korea's current foreign and security policy priorities. Why North Korea is fighting in Russia's war against Ukraine, and the consequences. How South Korea is responding to the North's more expansive activity. The North-South relationship now that unification is off the table. The impact on the military balance in North-East Asia and the US alliance system. · What framework should replace unification and denuclearisation. Sanghun Seok is a former South Korean career diplomat, a PhD candidate at the University of Cambridge, and a Senior Associate Fellow at RUSI. Dr Edward Howell is a Lecturer and Research Fellow at the University of Oxford and the Pharos Foundation, specialising in North and South Korea. His new book, A New Axis of Upheaval: North Korea, Russia, China, Iran, is released in December 2026.

The Future of War: How Autonomous Systems Are Reshaping Conflict
General David Petraeus discusses autonomous warfare, drone technology and the military transformation driven by Ukraine. Ukraine offers the clearest evidence that warfare is changing in revolutionary ways. Unmanned systems now account for nearly 90% of Russia's killed and wounded on the front line, with around eight million drones produced by Ukraine every year. Software is updated weekly and hardware every few weeks, a pace no Western procurement system matches. Traditional armoured manoeuvre has effectively stopped, replaced by a dense zone of surveillance and strike drones along the front. For Gen. Petraeus, Senior Vice President of RUSI, this demands a complete institutional overhaul, covering doctrine, force structure, training, procurement and personnel, on a scale far beyond the changes he oversaw during the Iraq surge. He argues the UK is unusually well placed to lead this shift, given its visibility into the Ukrainian battlefield, political continuity across governments, and a parliamentary system that can move fast, though entrenched interests in legacy platforms will resist the change required. Key themes discussed: The rise of drones and unmanned systems in Ukraine. Ukraine as a laboratory for the future of warfare. Why militaries need to rethink force structures and procurement. The shift from remotely piloted to autonomous systems. How artificial intelligence could transform military decision-making. Changes needed to training, education and personnel. Institutional and political resistance to replacing legacy systems. Why the UK is particularly well placed to lead military transformation. Gen. David Petraeus is Senior Vice President of RUSI, former Commander of US Central Command, former Commander of the Multi-National Force in Iraq, and former Director of the CIA.

Great Power Diplomacy: How to Prevent a Third World War
In this episode, Tobias Ellwood sets out why he believes we are drifting towards global conflict, and what can still be done to stop it. The order that has held since 1945 is coming apart. War in Ukraine, confrontation between the US and Iran, unresolved conflict in the Middle East and an intensifying rivalry between Washington and Beijing have produced the most dangerous strategic environment in a generation. Recorded during a live RUSI members webinar on 19 August 2026, this special episode features RUSI Distinguished Fellow, The Rt Hon Tobias Ellwood, discussing his new book: Ten Steps to Prevent World War Three. The webinar was chaired by RUSI Senior Associate Fellow Professor Beatrice Heuser with an audience Q&A. Key themes discussed are: How the West arrived at this point, and why the rules-based order has broken down. Where the risks of escalation are greatest, and how much of it would be deliberate rather than accidental. What grey zone warfare means for deterrence and Western defence planning. How artificial intelligence and computing will shape the speed and character of future conflict. The full recording is available to RUSI members on the Institute's website, where you can also sign up if you are not currently a member.

Energy on the Frontline of European Security
Energy is no longer the preserve of the business pages and is central to questions of European Security. Disruption to shipping through the Strait of Hormuz has left European gas prices far above where they sat at the start of 2026 and reserves are lower than where they need to be for winter. Jet and diesel markets are tighter than at any point since 2022. And, across the North Sea, unexplained drones and loitering vessels have become a routine feature of offshore operations. In this episode, Andrew Gee, Director, International Security at RUSI, is joined by Amund Vik, senior advisor at Eurasia Group and former head of strategy and policy for the Norwegian Labour Party, and Petras Katinas, a research fellow in climate, energy and defence at RUSI Europe. They discuss the following core questions: How exposed will the United Kingdom and Europe energy markets be this winter and is more North Sea energy production any kind of solution? Who does Europe now depend on for its energy? Is that reliance a partnership or a vulnerability? If energy infrastructure is now a target, what does defending it require? Would a turn to civil nuclear power change the picture?

Japan's Intelligence Reforms
Japan's significant intelligence reforms reveal how the country's approach to security is becoming more self-reliant and autonomous. But what is being proposed, and why now? In this edition of Global Security Briefing, host Philip Shetler-Jones, Senior Research Fellow, Indo-Pacific Security at RUSI is joined by Ken Kotani, Professor at Nihon University, Japan and James DJ Brown, Professor of Political Science at Temple University, Japan Campus, to reflect on how Japan is rebuilding its national intelligence capability. They explore the following core questions: Why is this important in terms of the history of the country? What are some of the obstacles? What does this reform tell us about how Japan is changing in terms of its self-perception and threat perception? What are the implications for Japan's relationships with allies and adversaries?

After Ankara: First Reflections on the 2026 NATO Summit
The 2026 NATO Summit convened at a moment of fragile unity for the alliance. What did it deliver? What did it leave unresolved? In this episode of Global Security Briefing, RUSI's Director-General Rachel Ellehuus is joined by three colleagues, each bringing with them a different perspective on the alliance: Natia Seskuria, Senior Research Fellow for Russian and Eurasian Security, Burcu Ozcelik, Senior Research Fellow for Middle East Security, and Oana Lungescu, Former NATO Spokesperson and RUSI Distinguished Fellow. Burcu and Oana join the recording from Ankara and offer their reflections on the atmosphere on the ground. The three core questions explored in this episode are: What did the summit tell us about how NATO as a whole – and individual members – view Russia? Second, what does the summit and its mention of Iran mean for the Middle East, and where does the region now sit among NATO's priorities? Third, what does the summit mean for Europe, and where does the transatlantic relationship now stand? What about the roles of Turkey and Ukraine?
