Jesus, your reading comprehension skills leave a lot to be desired.
Firstly, you suggested Russia take a leaf out of the US book on anti-terrorism 'vengeance' (the meaning of which I can only guess at). I pointed out that they are doing quite well on their own in terms of 'vengeance' e.g. Grozny. To which you reply you're simply hoping terrorism is wiped off the face of the earth, as if that would justify indiscriminate shelling of civilians... or the US equivalent of carpet bombing Baghdad or Kabul with B52s - the latter is a hypothetical example.
I certainly wasn't saying the US is guilty of the same acts perpetrated by Russian forces, and if you didn't have head up your arse you might have realised that.
Now, if that's not getting through to you...
