Unfortunately drones don’t hold territory.
Same as V1 and V2.
Ukraine is losing ground, every day.
Eventually they’ll get depleted, i.e. burn through a generation of men.
Horrible.
Nor do 19 casualties turn the tide of war. This "major" attack sure is flaccid.
Wonder weapons are often overrated. Three thousand V2 rockets killed something like 9,000 citizens in England, which is quite a lot. On the the other hand, it is only three per rocket. Given the cost to develop them and then to manufacture them, that is lousy yield. V2 rockets killed over 19,000 people in German territory during the manufacturing process.
The overall affect of these things is negligible.
