It’s also an incredibly graphic image as to the horrors of war. I would suggest reading up on what she has to say about it, her long friendship with the photographer, and how she has used this image to create the Kim Phúc Foundation which assists children in war town areas. You should try to understand why this image is OK, and why what you see as shielding a child is less helpful to what she herself doesn’t want to censor.
It is iconic because it is horrifying and that horror should make us all reconsider any military action.
