It's rough, though, because those things are what drive public opinion even though they're insignificant in the big picture.
The vast majority of humans don't make most of their decisions based on statistics, or deep historical understanding, or careful rational arguments. When it comes to casual viewpoints like their thoughts on another country or daily news items, they tend to make their decisions based on who they like, what their friends think, and how they feel emotionally. That's not an insult, it's just human nature. People don't want to dedicate hours of hard thinking to an issue like this, so they allow their subconscious to take control, and the subconscious defaults to associations and emotions.
Thus, control of the narrative and images like hospitals and babies and particularly sympathetic victims matter more to that narrative than the best historical book on the subject ever will.
