EUROPE - After the ceremony, Merkel and UN Secretary-General Guterres gave the opening speeches at a new peace forum in Paris set up by Macron - with both warning that rising nationalism threatens the rules-based international order. "The concern I have is that blinkered nationalist views may gain ground once again," Merkel said, warning that people were calling the "European peace project" into question. Guterres warned of "many parallels with both the start of the twentieth century and the 1930s, giving us grounds to fear that an unpredictable chain of events could ensue".
