I’m a bit puzzled by your claim here. The IDF has had ample opportunity to respond to these events, and has not claimed that they thought Hezbollah was present at the UN positions in this case. If it were the case that they thought that, by now they absolutely would have, yet you keep bringing it up as a likely reason? More generally, Unfil has never had a mandate of removing Hezbollah positions in southern Lebanon (that’s the Lebanese army/government’s job, of which there basically isn’t one of either). Their mandate is only to monitor. Their specific mandate is to “allow” everything and tell the UN about it. I’m frankly puzzled about your arguments here.
