Holding the Line: NATO’s Eastern Flank & Resistance.

Martin Sklenár, Director of GLOBSEC’s Future of Security Programme, speaks with Estonian parliamentarian Raimond Kaljulaid on NATO’s eastern flank, Russia’s expanding use of grey-zone tactics, modern intelligence sharing, and the lessons Estonia offers for today’s security environment. A timely conversation on how deterrence, resilience, and cooperation are being reshaped as security threats intensify across Europe.

Some of the key episode questions include: 

• How has NATO’s eastern flank evolved since Russia’s full-scale invasion of Ukraine, and where do the biggest vulnerabilities remain?
• What do Russia’s grey-zone tactics look like in practice, and how should democracies respond without escalating conflict?
• How is intelligence sharing adapting to hybrid threats, cyber operations, and disinformation campaigns?
• What lessons from Estonia’s security model are most relevant for allies seeking to strengthen resilience today?
