What things are worth fighting for? What things are worth dying for? Are some wars ‘better’ than others? Are some weapons too terrible to use? If so, who gets to decide?

Join Dr Rory Cox and Peter Caddick-Adams as they discuss ancient and medieval warfare and military ethics, and what they can teach us about today’s international conflicts.
