Just goes to show that all sides are as bad as each other when it comes to desecrating countries heritages. We look at countries in eastern europe and wonder how they can ruin cities like that yet we have done the same to others.
Yes it was nasty of us to bomb the Germans back.
The only reason they didn't flatten our cities was they designed the Luftwaffe to,support the ground forces and didn't build heavy, four engined bombers. If they had then things would have been different. The Germans did far worse to Warsaw, the most destroyed city in the war (I'll bet most people don't know the second most damaged) Leningrad and Stalingrad with artillery.
