Global Security Briefing

As the Middle East is facing grave uncertainty against the backdrop of what is being called the 'Third Gulf War', Ankara is managing an uneasy relationship with Iran. Turkey is projecting itself as a more consequential regional actor across a variety of regional security spaces and is often described as a 'middle power'. In this episode of Global Security Briefing, Dr Neil Melvin is joined by Dr Burcu Ozcelik, RUSI Senior Research Fellow, to analyse Turkey's relationship with Iran and the main limits of Turkey's regional approach to diplomacy. This episode explores: · How Turkey approaches peacebuilding in the Middle East. · What Turkey's regional role is across different theatres in the Caucasus, Somalia and Iran. · The limits of eastern Mediterranean security architecture that excludes Turkey. · What British and European policymakers should learn from Turkey's approach to diplomacy. This podcast episode is part of a policy series for the 'Turkey's Peacebuilding in a Disordered Middle East' project of the Centre for Applied Turkey Studies (CATS) network.

Dr Eric Rudenshiold joins Neil Melvin to examine regional change, great-power competition and Washington's renewed engagement within the Caspian region. The Caspian region is being reshaped by new political and economic dynamics as Central Asia and the South Caucasus deepen regional cooperation and navigate the competing ambitions of Russia, China and a newly engaged US.

Trump's revived 'America First' policy is reshaping US-Latin America ties, testing regional stability, governance and the balance between Washington, Beijing, and Moscow. Nearly a year into his second term, President Trump has revived the 'America First' doctrine with a renewed focus on the Western Hemisphere. As Washington prioritises border security, transactional diplomacy and strategic competition with China and Russia, Latin American governments are reassessing how to navigate a more conditional and bilateral US approach. In this episode of Global Security Briefing, Neil Melvin is joined by Dr Carlos Solar, Senior Research Fellow for Latin American Security at RUSI. The discussion explores: · How the Trump Administration is reshaping US engagement with Latin America. · The effects of aid cuts, tariff threats and bilateral deals on regional governance. · Shifts in defence and security cooperation under the new US strategy. · How Latin American governments are responding to a tougher, more transactional Washington. · The challenge of balancing US pressure with growing Chinese and Russian influence.

The Royal Navy Fleet flagship in Asia prompts a critical question: How serious is Britain about the Indo-Pacific? Against a backdrop of deepening UK - Japan defence and economic ties, shifting US engagement, and growing regional security pressures, this episode of Global Security Briefing explores what the HMS Prince of Wales' 2025 mission reveals about the UK's approach to the Indo-Pacific. Host Neil Melvin is joined by Dr Philip Shetler-Jones to discuss how the deployment has been received in Japan and across the region, what has changed since the 2021 Royal Navy mission, and where Britain's Indo-Pacific policy may be heading in the years ahead.

Open warfare has crossed the Middle East, and in its wake came an erosion of the norms of statesmanship and the power of international law to avert conflict. What are the implications for deterrence, diplomacy, and the future of UK, US, and regional strategy? In this episode of Global Security Briefing, host Neil Melvin is joined by RUSI experts Burcu Ozcelik and Michael Stephens to assess whether the Middle East is on the cusp of fundamental transformation or simply entering another volatile chapter. With the region rocked by Hamas' October 2023 attacks, a devastating war in Gaza, direct military strikes between Iran and Israel, and renewed US intervention, long-held assumptions about deterrence, regional power balances, and the limits of escalation have been upended. As Prime Minister Netanyahu meets President Trump in Washington, the episode explores how far the region has shifted and whether latest confrontations mark the end of 'grey-zone' conflicts and the emergence of a new order shaped by overt state-to-state warfare. Has Iran's deterrence crumbled? Can Israel claim strategic success? Are Gulf states and the US recalibrating their roles? And what does all this mean for the future of Gaza, the Arab-Israeli process of diplomatic normalisation, and UK foreign policy?

Is there a real near-term prospect of an end of Russia's war against Ukraine? RUSI experts explain four and a half months of the Trump Administration's approach to the war. In this episode of Global Security Briefing, host Neil Melvin is joined by Professor Samuel Greene, who teaches Russian politics at King's College and is a senior fellow at the Centre for European Policy Analysis, and Andriy Zagorodnuyk, Chairman of the Centre for Defence Strategies, Kyiv, who also previously served as Minister of Defence of Ukraine (2019-2020). They examine Trump's approach to the war, which initially seemed to reposition the United States as a broker between Moscow and Kyiv, and expressed itself ready to cede key demands to Russia with the objective of bringing the war to a conclusion Talks have dragged on, and the US President has seemed to grow frustrated with the complexity of the issues and the pace of the negotiations. While initially welcoming Trump's approach to the conflict, Russia has seemed unwilling to genuinely commit, opting instead to prolong the process. The team outlines what will come next and how United States policy towards Russia and Ukraine is likely to develop in response to the Russia-Ukraine war.

GSB turns 100: RUSI experts look back on key security shifts and explore what's next for the UK in a rapidly changing global landscape. In this special 100th episode of Global Security Briefing, host Neil Melvin is joined by the RUSI International Security team to reflect on how global security has evolved since the podcast's launch in 2021. Recorded live in London, the episode examines a world marked by rising state-based wars, increasing military tensions, and the fragmentation of the post–World War II international order. From the Russia–Ukraine war and instability in the Middle East to the growing rivalry between the US and China in the Indo-Pacific, the panel explores the key trends driving today's global insecurity. The discussion also considers the rise of influential regional powers and the UK's search for a post-Brexit role on the world stage. The team also offers insights on the security challenges of the next five years. Can the UK and its allies adapt to an increasingly contested and divided global landscape?

As China increases its 'grey zone' pressure, can Taiwan defend its sovereignty without sparking open conflict? In this episode of Global Security Briefing, host Neil Melvin speaks with Dr. Philip Shetler-Jones, RUSI Senior Research Fellow for Indo-Pacific Security, Sze-Fung Lee an independent researcher specialising in Chinese hybrid warfare, and Dr. Jyun-yi Lee, Associate Research Fellow at Taiwan's Institute for National Defense and Security Research to examine how Taiwan is confronting the growing coercive pressure from China, a pressure which falls just below the threshold of war. Drawing on a new RUSI report, they explore what grey zone tactics are, how Taiwan is responding, and what lessons can be shared between Europe and the Indo-Pacific. With rising tensions in the Taiwan Strait, this episode asks: Can grey zone threats be deterred – and how close are we to open conflict? This episode is brought to you as part of our Indo-Pacific Security Programme, under which our research on the grey zone and lawfare receives sponsorship from the Taipei Relations Office in London.

How is the global security landscape evolving, and what role can think tanks play in shaping the debate?

They also discuss RUSI's role as the world's oldest security and defence think tank, its strategic direction ahead of its bicentenary, and how it can contribute to navigating an increasingly complex global environment. What are the biggest challenges for think tanks today, and how can institutions like RUSI help shape the future of security policy?
