Does “All Quiet on the Western Front” Predict Germany’s Grim Future in World War III?

Why is All Quiet on the Western Front parroted as a great anti-war message when it didn’t even work on its original audience? It didn’t work on the second, third, or fourth audiences either. What do you call a person who tries the same thing over and over again expecting a different result?

My guess is that All Quiet on the Western Front isn’t really about the futility of war, regardless of how the author tried for that to be the message. Unfortunately, in the real world, an artist’s intended message doesn’t matter. All that matters is what the audience interprets the message to be. The interpreted lesson, the real lesson, of All Quiet on the Western Front is not that war is bad. It is losing a war that is bad.
