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?
