If you believe Winston Churchill, it is very clear that Dresden was a "mere act(s) of terror and wanton destruction". I have said that the WTC attack was a mere act of terror and wanton destruction - with which I am sure TigersEye will agree.
I do not believe civilian terror attacks are justified - whether they were on Dresden or the WTC. But someone opened Pandora's Box and started targeting civilians for terror attacks with bombs - which Al Queda then copied. If you believe the quote TigersEye gave, Spaight admitted the Germans were doing tactical attacks - which complied with the laws of war. IMO the British attacks did not, since they deliberately targeted civilians.
And I stated that I know of no rational reason for Al Queda to attack the U.S. - therefore we did not deserve the WTC attacks.
I'll try to find my "Advance to Barbarism" book by Veale tomorrow since Tigerseye is doing his homework and making good arguments on this post. I'll have to do more homework on this topic to keep up with him.
Churchill isn't a god; he is as we all are - imperfect. You can selectively quote from him all you want but it won't justify 9/11 or the Nazi initiation of WW2.
