Rotterdam also comes to mind.
I also point out what the Nazis did to many of the citizens of Warsaw even before they leveled the city.
If only fallout wouldn’t have spread throughout the continent, I would have nuked the bastards.
Interesting note. The Dutch had capitulated on the afternoon of the bombing raid that destroyed Rotterdam...but the 90 German bombers did not get the recall radio signal and the city was destroyed.
And Warsaw before that.
