Can there be an end to war?

This year's Reith lecturer is British military historian and journalist John Keegan.

In his fifth and final Reith lecture, recorded at the Broadcasting House, London, John Keegan considers the future of war. He argues that it will not be law that will keep the world's peace. Rather it will be because the United Nations retains the will to confront unlawful force with lawful force together with the capacity to resolve the conflicts in which wars originate. He believes that we must not shrink from seeing the causes of war addressed, but equally we must not shrink from seeing violence used when the threat of violence has failed.
