Thank you 20driver for posting the full inscription. The fact that it "seems like a pretty accurate statement" is not the point, though. Historians and others with an understanding of strategic warfare will argue these points for years to came. New facts will come to light, similarly. It hardly seems appropriate, therefore, to present such an inscription as if the negators already have a proven point. Innocent until proved guilty is the phrase, I believe.
It still trots out the old chestnut that "the raids resulted in only small reductions in German war production". While the bomber force was being constructed, crews learned their trade and techniques and tactics were being developed, we know it did. What nobody has ever been able to say is what the German output would have been without the early raids. Even the morality of the Offensive is not clear cut. As Helpful Stacker points out, in his, own words, they started it. If we ignore the bombing of civilians in Warsaw, Rotterdam etc, we could not have ignored the bombing of London, Liverpool, Birmingham, Coventry etc. The bomber force was not used offensively against German towns until after the SEP 40 raid on London. As Arthur Harris put it himself, "They have sown the wind, and so they shall reap the whirlwind." The point I would make is that the "morality" can be argued from now until the last Archbishop; but it should not cast a slur of doubt on the men who did their duty.
Can't we send some of our spray paint wielding "yoofs" over there on cultural visits?
