I find this statement helpful:
This picture + quote comes from the folk over at Darkwood Brew. We do not need to demonize those who sought to express virtue by enlisting in the military, even if we disagree with many of the actions done by our military. Similarly, we do not need to glorify war even if good people participated in it. Humans can be imperfect, yet worthy of honor. War can be something we recognize as horrible without dishonoring all of the participants.
