Ah yes, the classic defense of squabbling children in the back seat. "They did it first!" Being the second to massacre a family of four isn't appreciably more awesome than being the first. And it sure wouldn't make a difference to either family.

First you're writing Iranian fanfic about how noble Iran never targets civilians. Now you're saying, 'Sure, they kill civilians but when they do it it's the good kind of civilian slaughter!' You're twisting yourself into some wild shapes to carry water for a tyrannical dictatorship.

And talking about the deaths of "random school girls" seems like little more than a propaganda point for you when you've discredited yourself about caring about civilian casualties at all. So long as they were killed by the right people, it seems like you wouldn't think there was anything inherently wrong with it.

This isn't hard though: when the US targets civilians, it's a war crime; when Iran targets civilians, it's a war crime. I couldn't give a single fuck who did it first.
