It seems these pagers were actively used by Hezbollah though. It was a targeted attack where, for once, Israel's target was not the murder of a civilian population.

Whether it was well executed is a completely different question. Did they successfully strike their targets, rather than bystanders or people who happened to get the wrong pager? Were there civilian casualties (as it seems there was), and were those worse than in what we would expect from other types of military operations targeting terrorist organizations? The answers are not simple yes/no, but gradients. Which is different from their ongoing genocide in Gaza, where the cruelty is the entire point.

Saying an attack isn't targeting civilians is a long way from saying it is legitimate. But coming from a regime that has been actively targeting civilians for months claiming that there is simply no other way of doing things, I guess this is at least evidence that they are aware of alternatives.

Hezbollah is attacking Israel from the north, and it would be naïve to expect Israel not to strike back. This attack appears to have lead to fewer meaningless civilian deaths than what we have come to expect coming fram Israel. That is all.
