My guess: speed. Until they hit the atmosphere, meteors are humming along at 25,000 mph or more. Early-warning missile detection systems would probably be tuned for much slower objects.
Also combined with angle or maybe overwhelming altitude. Since meteors come from practically infinite height, the missile systems might not be looking for anything there, and by the time one is or would be detected, it's gone.
Wouldn't it BE super intelligent to have a very large array of radio telescopes that observe the sky 4 extinction level meteors? Let's not let hindsight be 20/20, shall we? Pretty sure Japan has already been advocating for said preemptive measures with their inclusion of a meteor shower simulation as part of the opening ceremonies in Tokyo
No one in his/her sound mind would posit a sane argument against that, nor should anyone in their sound mind posit an argument defending an unsound mind to stop us from building, launching, and maintaining said radio telescopes in outer space, n'est-ce pas?
