Now in its third year, the Russo-Ukraine War has upended the post-Cold War security landscape, exposing deep fractures in the global balance of power. 

As western unity frays and U.S. diplomacy shifts under President Trump, the war has become a flashpoint for competing visions of the international order. 

This week, the European Union gave Russia an ultimatum: accept a proposed ceasefire or face expanded sanctions—just days ahead of a potential round of direct peace talks in Istanbul on Thursday. The stakes are high, and the choices made this week could reshape not only the trajectory of the war but the future of global security.

How should we understand the prospects for a sustainable peace in Ukraine amidst evolving geopolitical dynamics and continued battlefield uncertainty? 

To help make sense of these developments, Just Security Senior Fellow and Director of the Oxford Programme for Cyber and Tech Policy, Brianna Rosen, sat down with Sir Lawrence Freedman, Emeritus Professor of War Studies at King's College London and Professor Janina Dill, Dame Louise Richardson Chair in Global Security at Oxford University’s Blavatnik School of Government. 

This conversation was part of the Calleva-Airey Neave Global Security Seminar Series at the University of Oxford.
