Remember Hitler's "Armenian quote": . Accordingly, I have placed my death-head formation in readiness—for the present only in the East—with orders to them to send to death mercilessly and without compassion, men, women, and children of Polish derivation and language. --> and the Germans followed it through pretty well. The length and breadth of this country you'll find little monuments saying "here xx number of Poles were killed by Germans" -- you'll even find it in out of the way forests.
The Germans don't like the Allied bombing of Dresden? tough... I have no sympathy for that...
