Your last paragraph is really out there, making Israel worse because they may have accidentally killed more gays?
How about we don't cheer on either? How about we don't cheer at all? Innocent civilians are dying because a bunch of dictatorial egomaniacs want to feel powerful. I don't care what their nationality is, people are dying, I'm not cheering anyone.
Fuck the Israeli genocidal government
Fuck the Iranian murderous hateful theocratic dictatorship
Fuck the murderers from Hamas.
Take all of those against a wall and you finally might have a chance at actual peace there.
I'm not cheering, I'm crying for the people
