Abstract

Now in its third year, the Russian war of aggression against Ukraine remains at the very top of the international security agenda. This conflict has largely refocused the West's attention away from the counterterrorism and counterinsurgency campaigns that followed the terrorist attacks of September 11, 2001. In February 2022, German chancellor Olaf Scholz went so far as to declare that the invasion signaled a zeitenwende, or “dawn of a new era.”1 Russia's aggression and the threat of having to fight a peer or near-peer competitor raises difficult questions, many of which are ethical in nature. The essays gathered in this roundtable seek to provide answers to some of those questions. They are the result of a workshop I organized for the King's College London Centre for Military Ethics in October 2023. One of my ambitions for this workshop was to put leading academics working on the ethics of war into discussion with military practitioners, making sure to include Ukrainian voices. I was very fortunate to succeed in these objectives, and I am convinced that the published essays have benefited enormously from our conversations.
