What does it take to build lasting peace — and secure it? What kind of security guarantees can truly deter renewed aggression? In this episode of Lawyering Peace, Dr. Paul R. Williams is joined by Lesia Ogryzko, Director of the Sahaidachnyi Security Center, and Julian Braithwaite, former UK Ambassador to the UN and WTO, to unpack what a post-war security framework for Ukraine could and should look like. Together, they explore how to negotiate credible security commitments that reflect the lessons of past failures — while embracing future-oriented strategies for deterrence, resilience, and international coordination. From the role of the EU, US, and NATO, to the engagement of global players like China, India, and Brazil, the conversation examines how a pluralistic, robust security architecture can emerge from peace talks. The episode also confronts hard realities, including Russia’s continued threats and the challenges of military demilitarization demands. 🎧 Tune in for an expert dialogue on peace, power, and post-war security strategy.
