well two things: 1) Iran doesn't have much in terms of drones, but they are not using them nearly as much as even Russia, much less Ukraine. Look at US bases in the area: there's been a few flyovers by drones but no serious attacks, but US bases haven't even put up nets or anything to protect resources, they still have radar and high value targets just sitting out in the open unattacked. 2) Iran still hasn't lost any territory, that's the defense I'm talking about. The US and Israel can expend all their bombs, but that doesn't bring down Iran's government or lose them any land. At most it loses them economic power. So I don't think Iran demonstrates much at all about the modern use of drones.
