Here is an article by Edward G. Lengel on the last remaining World War One veteran, belatedly included. It's an excellent disassemblation of the American prediclition to ignore veterans. From the article:
But there are some stories that Americans would rather not hear. If war tales aren't thrilling, readers and armchair Napoleons aren't interested. The Civil War and World War II seem to lend themselves to good storytelling, as long as one avoids the ugly, depressing bits. They appear to have clear beginnings and endings, with dramatic heroes and villains. They move. World War I, by contrast, with its images of trench warfare and mustard gas, is not so easy to manipulate in a marketable manner. Popular historians consequently avoid it. As one trade publisher recently told me, World War I has "poor entertainment value." Attempts to discuss it, even with avid students of military history, often end with the same comments that veterans heard back in 1919: "It's all too dreadful," and so on.
We should step back and think for a moment about what this says about Americans as people. Do we honor our veterans for all their sacrifices, or do we care only if they can tell us a good story? And who, then, is guilty of ingratitude?
