    The asteroid that wiped out the dinosaurs would be insufficient to eliminate a life bearing planet as a potential future source of a threat appearing, unless you hit such planets regularly in that manner every few million years or so. If you were really going to do a policy like this, you’d want to hit the planet hard enough to completely sterilize the place, or at least kill off everything bigger than a microbe.

      Hmm, ok - what if it wasn’t meant to sterilize the planet, but instead annihilate the food chain and create such an interruption to continuity that the dominant life form (Space T-Rex) gets wiped out?

      Why no one has bothered us, the planet is already listed as “Solved” so there is no need to bother.

        The aliens would have to be stupid to list a planet as solved for tens of millions of years after killing off the dominant life forms, because, well, a new one will just evolve in short order, exactly as has happened on earth, and they ought to know this.
