Several cruise missiles where fired at the school specifically. And anyways, “we didn’t really want to bomb the school” is a sorry excuse.
We could pose it as a simple question and examine what the answers would be:
Do western powers bomb civilians intentionally?
US -> No
Israel -> No
Other westerner powers -> No
Iran -> No
Hamas/Hezbollah/Other terrorist murders -> No
It's a strange thing when you aren't even on the same page as your Iranian friends.
And intent matters. I for one support a form of reparations paid to the families of those who we mistakenly killed. Will Iran pay such reparations for those they've murdered inside and outside of Iran? Of course not. There's a difference - we're morally superior.
