   Just to be clear to everyone here:   
      
   I am not arguing that redirecting an asteroid would be a useful, an efficient,   
   nor even a necessarily effective means for an attack. It will likely take far   
   too much time and a considerable amount of resources, and trying to target the   
   damn thing will be    
   next to impossible.    
   My ONLY point, addressed in my second response, is that it WOULD be an option   
   available for consideration by a space-faring population that might not have   
   the material or intellectual resources required for buiding and deploying a   
   nuclear warhead.   
      
   In short, I think it is as bad an idea as anyone else here... but going   
   nuclear might not be an option (the closest thing to a nuclear option for them   
   might be to steer one of the Earth-provided nuclear drives into the   
   atmosphere, protected with a    
   carefully calculated amount of material, and let it crash into the target,   
   letting the nuclear fuel spread into the wind and contaminate the local   
   habitable area).
