"That other significant event doesn't 'commemorate' those who might die in wars to come."
I've always understood Remembrance Day as being in honour of those who lay down their lives for the service of their country and the world. I don't see how it matters whether they have already done so or not: the sacrifice is no less worthy of respect just because hasn't actually happened yet, although we surely hope that it doesn't need to. Maybe you choose to remember only those deaths past, rather than those yet to come. That strikes me as a personal choice, rather than the only correct interpretation rendering all others invalid.
