My point was that Ukraine doesn't buy 2 millions civilian drones and use them as killer drones. Ukraine is actually producing killer drones.
If you are good at producing civilian drones, it doesn't mean that you are good at producing killer drones because the specs are pretty different. If you subsidise heavily a civilian company making survey drones, for instance, and then try to attach a bomb to those and send them in a war zone, they won't do much today. In the end you will have subsidised work that went into making a drone that can make hundreds or thousands of flights during its lifetime, never fall from the sky, lands smoothly, doesn't make too much noise, follows drone regulations in civilian spaces, etc. But none of that work is useful for a killer drone (that has a lifetime of 25min in a war zone). On the other hand, your civilian drones will not have the ability to lock a target and crash into it, fly in GPS-denied environments and a jamming-resistant radio.
