Imagine the cost of a shahed drone being as low as $5,000, or less. Imagine the cartels south of the U.S. having tens of thousands, maybe hundreds of thousands of them. It could get painful fast. That's one thing this war is showing.
It was obvious ten years ago that this was coming, but saying so just made you sound crazy.
I said a similar thing when the Nordstream pipeline was popped. Basically anyone with, say, $400k to rent a boat and a work class underwater ROV could have done it. Sure, pricey, but that's low enough that a single individual could have financed it.
I dunno anyway. Buying a roll of a thousand of some component here and there wouldn't appear on anybody's radar. Maybe the motors would be a problem, but then, Mexico has enough good enough motor factories.
