In what sense.
If it wasn't a mistake (meaning someone wanted to kill 170 girls), then someone's going to hang.
If it was a mistake, it was a mistake. It happens.
What isn't a mistake is the 36,500 people killed by the security forces in IRAN. But everyone seems to think a girls school being bombed is more significant.
I don't care about regime change.
At the same time, I am not going to live on the same block with bully who thinks that they can pull the BS that IRAN has pulled for years and not retaliate.
IRAN is going to suck on it. And if the people won't rise up, they'll get it coming and going.
IRAN has already pretty mush isolated itself from the rest of the middle east. Rocketing their neighbors FOR NO GOOD REASON hasn't helped them.
