For much of history human life has had little value. Enemies were killed in the most painful and prolonged ways. This was true for a thousand years in Constantinople, in Tudor England, in Spain during the Inquisition, and at other times and places too numerous to mention. In times of war, the policy was often for the victors to kill men, women and children, or sell them into slavery, then destroy the cities and sow salt into their fields. Pogroms in recent times, and genocides, show us that many societies have not valued human life outside their own tribe. Why do you think that our view is right and the weight of human history is wrong? If Stalin or Hitler had prevailed against the West, what would we believe today? What will our children believe in future, if our way of life falls to the Middle Eastern radicals or to Putin's schemes?
