I think they're implying this mostly hit Hezbollah members, not than none of the victims were innocent.
That said, you do know Hezbollah is basically the same as Israel, just without the backing of the USA, right? They also want genocide. The way this was dealt with was one of the best options when dealing with a group that wants to genocide your country. It also shows Israel chose to start the war with Hamas, and likely allowed the October 7 attack to happen, if they've had this capability all along.
The dad who's girl died literally brought this on himself. He chose religious fanaticism over family. He's in Lebanon, not Gaza, not West Bank - he could have chosen not to be part of a group that wants to wipe out a whole nother group. This is on him the same way it's on an antivaxxer when they're kid gets sick. There's plenty of damn good reasons to wish Netanyahu dead and in hell, but this ain't one. I doubt him and his right wing extremist possé came up with this operation since they would have deliberately chosen something with way more innocent casualties.
