Richard Dicker of Human Rights Watch writes to announce an online debate concerning peace and justice that The Economist started running this week. Per their Oxbridge debate format, they asked Richard to support the motion 'This house believes that punishing wrongdoers is fundamental to securing lasting peace'. Jack Snyder, the Robert and Renée Belfer Professor of International Relations at Columbia University, is opposing the motion. The debate is being 'moderated' by Bruce Clark. He is one of their correspondents who has written on this topic. The Economist has run several debates for over the last year and they say these 'are often the most popular articles on our site and receive a great deal of reader feedback'. The debate can be found online at www.economist.com/debate.
