It is a stretch to call a pager a military equipment and the use of one a “military operation”.
No, Israel rigged consumer electronics used by people during their civilian lives off the battlefield as they posed no threat to anybody. There is no definition of terrorism which doesn’t encapsulate this act.
And no, this act is not justified even if every targeted victim of this attack was a Hezbollah member. As I said before, there are more members of this organization than fighters and generals.
No, that's not what the reporting says. Hezbollah operates its own military networks for these things, procures these pagers specifically for military purchases, and issues them to Hezbollah fighters.
"Off the battlefield" doesn't mean anything here: if they're members of the armed wing of Hezbollah, they are black-letter IHL combatants whether or not they're actively engaged in combat, the same way everybody aboard a naval vessel is a combatant if you sink it, including the cook.
Put it this way: if it turns out that these pagers were widely used by non-military personnel, like school teachers, I'll absolutely say I was wrong, and that this attack was probably hard to justify. If reporting firms up that these pagers exclusively carried by military personnel, does that change things for you?
One of the casualties was the child of an MP. That is not military. So we know of at least one instance of a non-military member being targeted, and their kid killed.
Israel has consistently lied about the military nature of their targets in Gaza. I see no reason to believe they behave any differently in Lebanon.
Also, even if they were all military—which they probably weren’t—they were still going about their civilian lives far away from the battlefield, as they posed no threat to anybody.
Now that some time has passed we know a little more about the victims. Including a press conference by Lebanon’s Minister of Health Firass Abiad. There have been 12 recorded deaths so far. Of those were 4 medical workers, one 8 year old girl, and one 11 year old boy. The press conference noted that many of those carrying the pagers were civilians. And made special mention of the toll this scale of an attack had on their medical system.
The best interpretation for Israel here is that they conducted a terrorist attack in a civilian against an armed group during their civilian lives, inflicting at least some civilian casualties. But we know how Israel conducts it self in Gaza and elsewhere in Palestine, and we have every reason to expect their intentions were far more nefarious.
The answer is no. The nature of the attack does not make it OK even if it turns out that only military personnel had these pagers. It is not OK for Israel to weaponize consumer electronics which are widely used in a civilian area, even if the users at the time are most likely military personnel.
But this question is irrelevant because this is very unlikely to be the case. The victims seem to be many civilians.
