This attack on the school comes up all the time as a talking point. And I will tell you exactly how most Iranians react: they find it weird that you’ll talk about this school, but you won’t talk about the thousands of protesters killed by the regime.
Yes. People die in war. It’s sad. But most Iranians will say “whether we go to war or not Iranians are being killed” and it’s better to fight for regime change than to just accept the status quo.
Imagine being against the American Revolution because some innocent civilians will get killed? Yes, people die in war, but if there’s a chance for something better than it’s definitely worth it!
Every Iranian I know thinks it’s worth it and they danced in the street when Khamenei was killed.
