John Paul II surprised pilgrims when he publicly recalled his own experience of war in explaining his opposition to military intervention in Iraq. "I belong to that generation that lived through World War II and, thanks be to God, survived it," the Pope said, after praying the midday Angelus with the crowds gathered today in St. Peter's Square. "I have the duty to say to all young people, to those who are younger than me, who have not had this experience: 'No more war!' as Paul VI said during his first visit to the United Nations," he added. "We must do everything possible. We know well that peace is not possible at any cost. But we all know how great this responsibility is -- therefore, prayer and penance!" he exclaimed.
