"The expansion of Europe was a phenomenon of such magnitude with such a profound and irreversible effect on humankind that it might be thought that our moralising tendency would be silenced in the face of it. But as we saw on the 500th anniversary of Columbus's voyage in 1992, there are those who think that its disastrous consequences for indigenous people make it quite definitely a bad thing which should not have happened. Unprovoked invasion of the territory of another society is immoral by our standards and breaches current international law, but if these be the standards we apply to history there will be no end to our condemning."
