Asymmetric warfare, a concept that costed the USA a few trillions before. A patient observer of the war in Ukraine could have updated some war doctrines. If you are an American tax payer, I would understand it if you were banging your head on the table right now. These flying lawn mowers are perfect for a Denial of Dollar (DoD) attack.

A patient observer? Any random idiot of the street that cares to watch the news occasionally could've figured that out.

Oh I am, and my representatives hear from me very, very often. Unfortunately, it falls on deaf ears. Seemingly no one around me cares, and our leaders certainly don't. I feel like I'm going insane and living in some kind of weird bizzaro world.

Shooting Patriots at flying lawn mowers (I suppose you mean Shaheds, Gerberas, and the like) is crazy. Patriots are key to shooting down ballistic missiles.

To the best of my knowledge, the explosives-laden lawn mowers flying over Ukraine are mostly destroyed by cannon fire from the ground, cannon / machine-gun fire from aircraft (including converted GA aircraft), and interceptor drones.

I expect the US armed forces to be testing oodles of various cheap drones by now. E.g. the US has used Shahed-lookalike drones while attacking Iran recently.
