They don't see atrocities as the result of a system, just outliers, mistakes, bad individuals, and other things they can overlook.
Whereas showing them every single military conflict the US has engaged in since WWII, it's much harder for them to say "Oh, yes we were wrong all those other times, but Ukraine or China or Iran or <future conflict> is different"
