alt Hacker NewsYou seem to be under the impression that they targeted pagers that were distributed through civilian channels. These were pagers that were purchased BY Hezbollah to be used on Hezbollah's private, secure network, not on a public network. These were not pagers used by a hospital for normal healthcare work. Healthcare workers were carrying these pagers because Hezbollah effectively serves as a shadow state in Lebanon. So if a healthcare worker had one of these pagers, it was because they were part of that hierarchy.
Again, so what? You aren't off the hook because of the actions of your enemies. It was obvious these would be going off around civilians, in homes and public spaces, including hospitals, and they chose to go through with the attack knowing this. That the civilians who would be around them would have no particular reason to fear or suspect this attack, because the vector was a common daily object.
It was an attack on civilians in pursuit of a non-military political goal. Terrorism. I think it was pretty successful on the terms of the people who carried it out but call it what it is.
