I think the use case is attacking Israel. It’s damn hard for a terrorist that isn’t already inside Israel to cross the border between Israel and its neighbors in a truck and then start running people over. But sending drones over the border can be a lot easier.
Would Hezbollah hesitate to fire these things at Israel if it had them? Would they have better ways to kill a lot of Israelis, since they haven’t been able to successfully target their explosives at any critical Israeli civilian infrastructure?
I think Hezbollah is exactly the kind of non-state actor that would very much want this kind of weapon in order to actually use it, and they already get weapon supplies, including drones of various kinds, from Iran.
I am very much reminded of the nostalgebraist post models may behave differently in graded episodes (a tirade).
