Sorry Bob, but that's the Russian soldier in you talking. Most of us are not that uncivilized. Unfortunately for the Ukrainian civilians many Russian soldiers think just like you.
Civilized people know that history is not an excuse for violent attacks.
Life is so easy for a dog. No worries about tomorrow, or YESTERDAY* - just grab that piece of meat in front of you!
*no need to learn history, none whatsoever, for a dog.
