A national memorial isn’t a meant to be a grave stone. One of the criticisms of the Vietnam Memorial was that it felt like that. A national memorial is for the whole of the nation, not only to honor the veterans.
I think we lose sight that war impacts the whole country not just those who serve in it. War somehow became seen as a private enterprise that happens “over there” and not the whole of nation event that it is. That is something very hard to capture in a memorial.
Memorials are not just for the fallen but for those who made it through, their families, their friends, and everyone connected. GWOT especially changed the whole nation. It changed how people talk, how they dress, and who they elect. It lasted 6x longer than WW2. It’s a very deep topic that is hard to memorialize.
With the GWOT memorial discussion, among other things, some people seem very upset about not having names of the fallen.
While the Vietnam Memorial set the standard here, it's the anomaly. WW1, WW2, Korea don't have a roster of the dead.
