Just start from the premise that Israel targeted exclusively handheld military comms devices that would in ordinary practice only be in the custody of Hezbollah combatants, and from the additional premise that the explosions in the strikes were relatively small, so small that the overwhelming majority of the Hezbollah casualties were wounded and not KIA. Then try to make another story make sense.
We have significant evidence for both these premises!
This is not an argument that the strike incurred no civilian casualty, that no child of a Hezbollah combatant was in close proximity when one of the bombs went off, anything like that. It's rather a sanity check on arguments based on statistical claims about the casualties. There might have been quite a lot of civilian casualties! But for there to have been significantly more of them than combatant casualties, I would argue that you have to break one of my two premises.
Premise 1: The pagers were military devices, but based on what we know about them, it is impossible to assert that all were in the custody of Hezbollah combatants at the moment they exploded. One would need to prove that the pagers were physically on the combatants’ persons—and not, for example, sitting on a coffee table or elsewhere—at the time of detonation.
Premise 2: The physical location of the pagers directly affects the pattern of civilian injuries. Hospitals reported that many of the injured were civilians, including children, women, and non-combatants who were at home, at work, or in public areas. Even pro-Israel outlets, such as the Times of Israel, reported the same distribution of casualties.
Footage from Reuters, Al Jazeera, AP, and local Lebanese reporters shows numerous injured civilians with bandaged hands and faces, including people hurt inside homes, markets, farms, and workplaces, as well as children with hand and facial burns.
Now I would pose the question to you, why is your (likely novice) understanding of explosives and the footage you seen enough to overwrite the opinions of the hospitals and government of Lebanon?
