The Balkans: Europe's Missing Piece

In this episode of Coffee With Ken, we sit down with Dame Karen Pierce DCMG — former UK Ambassador to the United States and the United Nations, and current Special Envoy to the Western Balkans — for a conversation about the region she calls “the missing piece of the jigsaw” in Europe, and why it remains one of the most consequential flashpoints in transatlantic security.

Recorded live at the fourth annual London Defense Conference, the discussion traces Dame Karen’s career across four tours in Washington and the United Nations, and into her current work navigating the legacy of the Yugoslav wars, a conflict that, until 2022, represented the worst bloodshed in Europe since World War II. Together, Ken and Dame Karen unpack how Russia uses disinformation, organized crime, and political interference to keep the Balkans destabilized, and why the region’s path toward NATO and EU membership matters as much for European security as it does for the countries themselves.

The conversation also covers the urgent need to scale up defense production across the transatlantic alliance, the future of NATO over the next three to five years, and the growing wave of defense manufacturing cooperation between the US and UK. Dame Karen and Ken also discuss what re-industrialization means for how the next generation is trained, and why community colleges may hold more answers than four-year degrees.

The episode closes with Dame Karen’s hard-earned reflections on diplomacy: the importance of listening, understanding adversaries as well as allies, and why rebuilding people-to-people ties between Americans and Britons, especially among younger generations, matters more than ever.

This is a conversation about the parts of the world that don’t make headlines until it’s too late, the quiet work of diplomacy that keeps conflicts from reigniting, and what it means to stay vigilant in defense of a peace that’s easy to take for granted.

Key Takeaways from the Conversation

The Balkans Are Europe’s Unfinished Business
Dame Karen describes the Western Balkans as “the missing piece of the jigsaw” in the map of Europe, surrounded by EU members but not yet part of the union. Until 2022, the region represented the worst conflict in Europe since World War II, and the work of keeping that peace intact is far from finished.

Russia’s Strategy Doesn’t Require Troops
If Ukraine is Russia’s front door into Europe, Dame Karen argues the Balkans are the back door. Russia doesn’t need to send soldiers. It can dial up disinformation campaigns and lean on long-standing ties to organized criminal networks to keep the region off balance.

NATO Is Moving in the Right Direction, But Production Needs to Catch Up
Dame Karen sees a more capable NATO emerging over the next three to five years, with growing underwater capabilities and continued progress under AUKUS. But she’s candid that defense production across the alliance, especially ammunition, needs to scale up faster to avoid depleting allied stockpiles.

Re-Industrialization Is Reshaping How We Train People
Dame Karen points to a shift in how the US and UK think about workforce development, questioning whether a four-year degree is always the right path and pointing to community colleges as a model for adapting education to the needs of local industry.

Good Diplomacy Starts With Listening
Asked for her advice to leaders, Dame Karen doesn’t claim a secret formula. Understand your adversaries as well as your friends. Be transparent. Focus on shared long-term goals even when you disagree on the path to get there.

Why This Conversation Matters
Dame Karen Pierce has spent a career operating at the highest levels of international diplomacy, from Washington to the United Nations to the frontlines of European security policy. At a moment when attention is fixed on Ukraine, her perspective is a reminder that the Balkans remain unfinished business, and that the alliances keeping Europe stable require constant attention, not just in moments of crisis.

This episode is a reminder that diplomacy is rarely loud. It’s persistent, patient, and built on relationships, and it’s often the quiet work that keeps the peace from breaking.

At Coffee With Ken, these are the conversations that matter: exploring the people, institutions, and ideas shaping the future of business, policy, leadership, and civic life.
