"About 30% of Berlin's surface was destroyed during the WW2. In the case of Warsaw, however, estimates indicate that between 80-90% of the city was destroyed."

How funny is to make an example of 30% destroyed capital of invader who started the whole mess, instead of at least 80% destroyed capital of Poland, the biggest victim of those German barbarian invaders.

So, Warsaw looked like it practially had been nuked, and Berlin was in much better condition.
