I don't know if this would be a highly controversial opinion here, but I think that teaching people about the horrors of war isn't what stops war. It is the governments feeling the pain of war, such that they enact safeguards against easily going to war, and established norms to prevent the slaughter of civilians.

I may be mistaken, but I rarely see good faith efforts to, say, curtail the unchecked ability of the executive power to simply plunge into a de facto war without much direct authorization, or to use weapons such as the atomic bomb against civilians.

Let me add: visualizations like this are important, I think. I am not arguing against these, I'm just saying these probably don't produce political change.
