While the white phosphorus part doesn’t give you a choice, isn’t it basically that they used it only intending to hit military targets, then it turns out it hit civilians too?

I think it’s not a choice precisely because it’s the worst or most blatant war crime in the game IIRC and most people would decide against it even for “only military targets” and that would stop them from getting the point across.

It’s been a long time since I’ve played it so I might not be remembering entirely right. I might play it again now.
