If you send 100 drones and give me a machine gun I may be able to shoot a few down. You give me one these and maybe I can shoot down 90 of them. What would you prefer? Letting 10 through or letting 95 through?

Russia can’t stop the drones

Except they do. Ukraine and western media are publishing and riding hard every sussessful attack, but you never heard about the unuccessful ones because just think for a second, why they would tell everyone about failures. But just consider number of drones and missiles Ukraine is said to operate, and you would immediately notice they are either not using them or they do use it and fail most of the time.
