In the background lurks the scourge of international terrorism. There are people exercising power in a few countries and leading political factions in others who seem to be moved by narrow, brutal and irrational impulses. Their view of their own self-interest is so blinkered as to leave no space for purely human values, for peaceful negotiation or for economic advancement. They are bent on the destruction of the established order and of civilised ways of doing business. They must never be allowed to succeed.
