Save for a rare moment in classical antiquity, there has never been a century in which humans have not waged war. War is fought for all sorts of reasons, from petty, vengeance-seeking reasons to socio-political reasons. From differences in religion, to being slighted at having a woman stolen. Can you agree with any of the reasons war is fought? Is war ever justified? Under what conditions could you agree with a war being waged? Are you a pacifist?
