I take it “kinetic missile interceptor” refers to the interceptor, not the missile it is supposed to intercept. That the interceptor is just a dumb piece of iron once it has been shot.
I hope Rafael has a trick or two still up their sleeve when faced with missiles that can dodge. The interceptor will need some more smarts.
Obviously, this system only works against very dumb threats, but that is all Hezbollah has gotten from Iran.
