When Chancellor Angela Merkel thanked the Allies for the D-Day invasion and the “liberation” of Germany in World War II, she might have raised some eyebrows internationally. There’s no denying that the machine guns and howitzers firing at the Allied forces landing in Normandy 75 years ago were manned by German soldiers. When those other leaders went to Normandy for ceremonies on D-Day itself on Thursday, Merkel was back in Berlin, holding a regular meeting with governors and discussing bilateral relations with the prime minister of Kosovo.
