Did nobody here actually look at the school in question? The Iranians built a little kids school INSIDE a military base, a really important one at that. Same paint, style, literally ~20ft away.
A tragedy but it's hard to argue that it wasn't the intention of the Iranians for this exact senario to happen.
The USA has dozens of schools on military bases that house families of our soldiers. Is the intention that they be struck for propaganda? No. It's to educate their children just like in Iran.
