Talking Strategy

Royal United Services Institute

Our thinking about defence and security is shaped by ideas. What we see depends on our vantage point and the lenses we apply to the world. Governments, military and business leaders are seeking to maximise the value they gain from scarce resources by becoming more 'strategic'. Standing on the shoulders of the giants of strategy from the past helps us see further and more clearly into the future. This series is aimed at those looking to learn more about strategy and how to become more strategic – leaders, practitioners and scholars. This podcast series, co-chaired by Professor Beatrice Heuser and Paul O'Neill, examines the ideas of important thinkers from around the world and across the ages. The ideas, where they came from and what shaped those whose ideas shape us now. By exploring the concepts in which we and our adversaries think today, the episodes will shine a light on how we best prepare for tomorrow. The views or statements expressed by guests are their own and their appearance on the podcast does not imply an endorsement of them or any entity they represent.

    S7E3: Escape from the World-Island: Geopolitics and Geoeconomics

    Professor Scott Smitson traces the origins of geopolitics and geoeconomics as concepts and why these forgotten ideas are returning to shape today's world. The triumphalism following the end of the Cold War led some to believe we had reached The End of History, and that great powers had moved beyond a world shaped by geopolitics and geoeconomics. Robert Kaplan's The Revenge of Geography in 2012 challenged this view, arguing that geography still shapes how states see the world, and can either strengthen them or limit their ambitions. This is the core of geopolitics, an idea developed in the late 19th and early 20th centuries by thinkers such as Rudolf Kjellén and Sir Halford Mackinder. Drawing on the achievements of the Mongol Empire – see our discussion of its chief strategist, Subotai, in Season 4, Episode 1 – Mackinder believed that whoever rules the Heartland (Eurasia), commands the 'World Island' and thus the world. This was problematic for maritime powers, and later Nicholas Spykman argued that it was actually whoever controlled the Rimland, the coastal regions surrounding Eurasia, who controlled the destinies of the world. This was reflected in George Kennan's logic behind the Cold War containment strategy toward the Soviet Union. Its legacy remains in thinking about China, but does the Belt and Road Initiative suggest an attempt by China to break out of this singular characterisation and reduce its vulnerability to classical containment? Professor Scott Smitson is Director of the Grand Strategy Program at Denison University in Granville, Ohio. He served for 21 years in the US Army, including as a strategist at US Central and Southern Commands and the Joint Staff. Has also served for a period as a US Officer embedded in the UK's Ministry of Defence Strategic Plans team. Further Reading: Nicholas J. Spykman, Geography of the Peace, Harcourt, Brace & Co., 1944.

    S7E2: What Does a Return to Realpolitik Mean? With Professor John Bew

    What is realpolitik, and why is the world said to be returning to it? Professor John Bew CMG traces the idea back to its origins. The world may well be entering a new age of realpolitik, but the harder question is defining which kind. The term is usually associated with an unsentimental use of power to further national interests, often seen as a rejection of a more idealistic, values-based approach to international relations. But that's not where it came from. Realpolitik was first coined in 1853 by Ludwig von Rochau, a German liberal, who used it to describe something different: the ability to understand and adapt to the realities of power, and to pursue enlightened goals in a world that doesn't follow enlightened rules. For von Rochau, Realpolitik wasn't just about foreign policy – the strongest states, he argued, were those that could harness social forces at home and manage internal division effectively. Professor John Bew is a historian at King's College London and a leading figure at the Centre for Statecraft and National Security. He has advised four British Prime Ministers and authored three UK National Security Strategies. His book, Realpolitk: a History is a definitive work on the subject, just as are his biographies on Castlereagh and Attlee. Further reading: John Bew, Realpolitik: A History (Hurst, 2026).

    S7E1: Avoiding Strategic Surprise: Lessons from NATO with Dr Florence Gaub

    NATO expert Dr Florence Gaub explains how strategic foresight helps NATO anticipate and avoid strategic surprise in an uncertain world. Strategic surprise happens when new information fundamentally changes how we see the world. In an increasingly uncertain global landscape, predicting exact outcomes is nearly impossible – and that unpredictability heightens the risk of surprise. Yet as Lord Mervyn King explored in Season 6, genuine 'Black Swan' events – to quote Nicholas Taleb – are rarer than we think. Dr Florence Gaub describes how we can use strategic foresight to anticipate possible – even if unlikely – futures and avoid being caught off guard. She cautions, however, that it is not enough to 'think the unthinkable', futurologists also need to have their voice heard and acted on by those in power, so the work has to straddle both creative thinking and engaging with bureaucracies. Dr Florence Gaub is the Director of the Research Division at the NATO Defence College having previously worked at the European Union Institute for Security Studies. Her PhD in international politics is from Humbolt University. She is the author of Future, a User's Guide, a graphic novel for NATO called NATO, 2099, and editor of What If…?: Ten Dragon King Scenarios for 2030, which was published at the NATO Defence College in 2025.

    S6E22: Delivering National Security Strategies

    Former UN Ambassador and National Security Advisor Sir Mark Lyall Grant discusses the challenges facing delivery of Western security strategies. In this season of Talking Strategy we have explored many of the key themes of today's security and defence strategies, but the test of a strategy is what changes as a result. A perfectly written strategy that makes the wrong assumptions, or that cannot be delivered, is meaningless at best, and often worse. In the final episode of this season, we examine the vital question of how defence strategy is delivered. With so many Western strategies built on the assumption of a rules based international order, the fracturing of that system poses profound challenges for our defence strategies. Sir Mark, who chaired the UN Security Council four times, describes how the assumption was perhaps overblown – based on a 'Golden Age' that only lasted for 25 years – and how the world is moving in a disorderly manner towards a three-tier model in which interests are enforced through power. In this new world, governments need to confront the reality that they cannot guarantee the safety of their citizens alone or without the help of their populations. This affects how governments operate – their structures and processes – and the conversations they need to have with their people and allies.   Further Reading Mark Lyall Grant, 'The world order in crisis', Horizons: Journal of International Relations and Sustainable Development, vol.21 (2022): 124-133.

    S6E20: Preparing for War: Adaptable Forces and Societies

    Professor Olivier Schmitt describes the systemic challenges of military transformation, given rapidly evolving technology and NATO's distinct strategic cultures. Modern defence and security reviews highlight the deteriorating security environment and the need to prepare forces. But, as we hear from Lord King (Season 6, Episode 3), the ability to adapt will be essential; we need a mindset that allows for continuous change. This is both enabled by, and made harder within, an alliance context where members' different strategic cultures – with different civil-military relations, defence procurement and operations – present systemic dilemmas. Professor Olivier Schmitt is the Head of Research at the Institute of Military Operations at the Royal Danish Defence College. He completed his doctorate at the Department of War Studies, King's College London. His most recent book, Preparing for War: Strategy, Power and Military Change, was published by Hurst/Oxford University Press in 2026.   Further Reading: Schmitt, Olivier: Preparing for War.

    Bullion to Bullets: Mobilising the Financial Markets

    The Centre for Economic Security's Dr Rebecca Harding argues for the importance of financial markets as the fourth pillar in supporting effective mobilisation. Conversations about industrial mobilisation often focus on the triumvirate of government, armed forces and industry. In this episode we add a fourth pillar, that of finance, and the need for governments to consider how the economic system can be co-opted to the task of providing defence and security for their nations. Something that the US government recognised during the Civil War when, in 1861-1862, it issued the emergency paper current – the Greenback – to finance the war effort. The vital role of finance in recapitalising armed forces, and in building resilience, reinforces the need for comprehensive thinking about security discussed in earlier episodes and takes the task of mobilisation beyond defence ministries into all aspects of modern societies. Dr Rebecca Harding is CEO of the Centre for Economic Security and an independent trade economist. Her strategic advisory business, Rebeccanomics provides analytical services in international trade, trade finance and sustainability. She has also acted as a specialist advisor to the UK Treasury Select Committee. She published The World at Economic War: How to Rebuild Security in a Weaponized Global Economy (London Publishing Partnership, 2025) and has co-authored numerous other publications, including The Weaponization of Trade: The Great Unbalancing of Politics and Economics, in 2017. She appears regularly as a commentator on BBC, Bloomberg, Sky News and CNBC.
