This feels like moving the goalposts. The OP and the preceding comments are pretty clearly talking about the targeting mistake aspect of this incident, not the war itself. You're moving the discussion from the former to the latter to it easier to argue that US is in the wrong, but if the argument is that the war was unjust to begin with, then do you really need a school getting bombed to push you over the edge? After all, even if they bombed an IRGC compound and only killed soldiers, those soldiers are still people's sons, fathers, husbands. Even if there's no deaths, you could still make the macroeconomic argument that any economic losses are impoverishing the Iranian people.

No, I am fine with parent's take. We treat children as absolutely innocent (which they are, regardless of the way anybody tries to spin this or ie Gaza), and killing children is extra heinous crime compared to killing adult, same with rape etc. Children rapist get extra special treatment in jails, often from other murderers and society is largely fine with that.

As a parent, even when cutting off most of the emotions related to this horrible war crime, I am unfazed and unconvinced by such, even if well meaning whataboutism.
