In this episode Dapo Akande, Marko Milanovic and Philippa Webb, joined by Rebecca Barber and Mike Becker, examine various aspects of Russia’s war on Ukraine. The discussion begins with an evaluation of Russia’s legal justification for invading Ukraine, moving to an analysis of the responses to Russia’s aggression by the UN General Assembly and the Security Council. We then turn to the proceedings brought by Ukraine against Russia before the International Court of Justice pursuant to the Genocide Convention, the investigation initiated by the Prosecutor of the International Criminal Court, the commission of inquiry created by the Human Rights Council, and the pros and cons of an initiative to set up a Special Tribunal for the Crime of Aggression.
