> Except Israel invaded Lebanon before that. It also engaged in assassinations, espionage, terror and sabotage before that. In fact Israelis engaged in those even before the state of Israel was officially pronounced.

That is moving the goal posts, as these are not instances of attacking Iran, it's hard to claim Iran never attacked Israel first when it is either financing attacks against Israel or participating in them for the last 45+ years

> Israelis will say they invaded Lebanon in the 70s/80s because of the PLO, (no Hezbollah yet) however the PLO was itself a consequence of Israeli occupation of Palestinian territory.

Back when the PLO was founded there was no "foreign territory occupied by Israel", only internationally recognized Israeli borders and Gaza/West Bank which were under Egyptian/Jordanian occupation. Two countries that refused to create an independent Palestinian state
