Dear Victor, I'm afraid I have to slightly disagree with you. We too have memorial days, although not as intensely as the victorious powers celebrate them, for perfectly understandable reasons.
The National Day of Mourning (Volkstrauertag) is the most important German day of remembrance for the victims of both World Wars and other acts of violence. It is observed annually on the penultimate Sunday before Advent. In addition to the National Day of Mourning, Germany also observes the Sunday of the Dead (Eternity Sunday) in Protestant churches and the Christian holiday of All Souls' Day, both of which serve to commemorate the dead.
The significance of "Volkstrauertag" is: Commemoration of the victims of war, violence, and tyranny of all nations. There is a central ceremony in the German Bundestag, wreath laying ceremonies and memorial events in many locations.
And we have this organization, the German War Graves Commission (Volksbund Deutsche Kriegsgräbervorsorge), which deals intensively with this topic and has been working for years to commemorate the victims of the two World Wars internationally and to maintain and care for cemeteries throughout Europe, regardless of the soldiers' nationality. I am very grateful to this organization.
It helped me, after so many decades, to find out where my grandmother's son (whom I, of course, never met) died as a soldier at the age of 19 in WW I. I only remember from my childhood that she never got over it. She was simply informed that her son had died , but not where. She always thought it was in France.
A few years ago, I began to sift through the remaining documents and, with the help of this organization, discovered that he fell in a battle somewhere in a region (Galicia?) (now Ukraine), and that there is no grave.
My grandmother has been dead for a very, very long time, and I would have liked to share my research with her. However, the organization has created virtual memorials where every unknown fallen soldier is listed with their name and date of death. That way, at least they aren't completely forgotten and I am sure, that my granny would have found consolation in the fact, that her son had a at least a virtual memorial
I add the link of the organisation, in English, they have versions in most European languages.
