Generally quotes or copy and paste go into italics.
The "bomber will get through" and carpet bombing dogma adopted by the allies during WW2 was very much a prewar 1920s strategy, in no way a response to Germany. It claimed heavy civilian casualties would force an enemy to surrender without the need for a ground invasion. With the exception of the atomic bombs dropped on Japan it has never proved successful.
This bombing strategy lead Britain to neglect it's fighter defense force until the rearmament in 1936.
Chamberlain knew Germany were likely to bring war down on Europe. "Peace in our time" bought a bit of breathing space to continue the rearmament.
Hitler insisted that the first jets were developed as bombers. By the time they were introduced it was far too little too late.
Germany surrendered because of the ground invasion not directly due bombing.
Germany and Britain were far from "mortal enemies". Hitler admired the British, (I seem to recall that he considered us part of the aryan brotherhood). He hoped they would be allies or at least neutral.
WW2 didn't really "free" very many people. Arguably more people were left under imposed regimes than beforehand.
The history of Europe is pretty well established, with nuances for sure, so if you wanted to base your views on facts there are many good books on the subject. These threads are very good. I'd suggest Europe, A History, by Norman Davies, The Silk Roads, by Peter Frankopan, and because of the incredible parallels to the present conflict Crimea, by Orlando Figes.
Sadly too many global leaders seem to be pretty unfazed to annihilation, even of their own side, until it threatens there own skin.
