An important detail is that advanced western weapons are restricted to operations near our within the recognized borders if Ukraine. The arsenals, refineries, factories, and other strategic targets inside actual Russian territory have been hit with Ukrainian weapons. Most are relatively low payload drones, with some targets being serviced by Neptune land attack variants, which is definitely more advanced than anything in the Iranian arsenal for example. But I think the point stands that relatively cheap and simple systems have provided outsized results in the Ukrainian conflict.

The reason there are warning signs for Israel is because of the sheer economy of drone bombing. When Iran launched over a hundred drones, and only three hit, the media had a chuckle. I’m sure the IDF and the American planners supporting them looked very nervously at the estimated 2.4 billion USD worth of ordinance deployed during the defence. Why do you think Ukraine and Russia are building cheap drones to kill other cheap drones. It’ll be interesting to watch.
