Andrew Hussey on the legacy of France's Arab Empire

Tom Sutcliffe talks to Andrew Hussey about the often fraught relationship between France and its Arab ex-colonies, and how that plays out in the banlieues of Paris. The psychotherapist Gabrielle Rifkind recounts her experience of conflict resolution in the Middle East. While Rifkind emphases the need to understand what's happened in the past, the writer Ziauddin Sardar tries to imagine what the world would be like if we explored the future in a more systematic and scientific way.
