I think you are misunderstanding the point. Swap out 9-11 moment with “watershed moment”.

A drone doesn’t need to be able to carry more than 500-1000g to be an incredibly effective tool of war, and it absolutely was, basically, consumer grade drones that Ukraine used.

And all in all, probably, the whole operation cost less than a single tomahawk cruise missile.

I made this point that the article is making here, a few months ago. The US military industrial complex has completely missed the mark on where modern warfare is going., and the US has spent trillions to build a system that can be challenged for billions.
