Of course they don't. Their narrative only works when they can claim that random innocent doctors were innocently walking around with Hezbollah issued pagers.
I'm sure that innocent people have been maimed and, as somebody with a toddler that regularly picks up my phone, I dread to think about the children hurt and killed by this operation.
Unfortunately, war isn't a nice thing and innocent people do get killed. Hezbollah are a banned terrorist organisation and are the aggressors in their conflict with Israel. Israel does have the right to defend itself and kill Hezbollah terrorists wherever they are.
The genius and tragedy of this operation is that the terrorists clearly didn't suspect their electronic devices were capable of being used to kill them. This means they wouldn't have taken precautions to keep them out of the hands of their children.
I, personally, don't think I could have pressed the button to detonate the pagers knowing that young children, similar to my own, would likely be killed - but I do think it was a legitimate operation given Hezbollah's campaign of terror against Israel.
