The Germans showed no mercy, why should they expect any? They can revise history all they want, they sowed the wind and reaped the whirlwind...and a few firestorms.
Warsaw was one of the most beautiful cities in Europe before the War, the Germans virtually destroyed all of it.....after the war, Warsaw was rebuilt, but in the image of their Soviet masters, save for Stare Miasto, and very few of her post-war inhabitants had ties to the pre-war city, Warsaw literally had to be started back up from scratch.
So again, forgive me, if I don’t shed a tear for Dresden.
