In this episode of the Peace Corner Podcast, former U.S. Navy Captain and Foreign Area Officer Bill Miller joins Michaela to explore how peacebuilders and defence institutions can work together to build more sustainable and effective approaches to peace. Drawing on more than three decades of military service, Bill reflects on how his understanding of peace evolved from the cockpit to the embassy, highlighting the importance of diplomacy, trust, and international cooperation alongside military capabilities. Together, they discuss the role of security cooperation, the value of understanding institutional systems, and the often-overlooked mechanisms through which defence institutions contribute to conflict prevention, human rights, and peacebuilding. The conversation also explores the practical realities of working in fragile and conflict-affected contexts, the challenges of balancing security with human rights, and why long-term relationships, cultural understanding, and patience are essential to building lasting peace. Bill concludes by sharing advice for the next generation of peacebuilders, encouraging them to become practitioners, understand the systems they seek to influence, and recognise that meaningful peace is built through cooperation and trust.
