Oh I agree with you. It is just that the dam busters raid was such a powerful propaganda piece - "English ingenuity over the Evil Empire" type thing, and I truly do admire the technical skills and bravery involved in the whole raid.

But the downvotes that my comment above (and no doubt this one) gets just exacerbates the whitewashing of Allied atrocities during WWII. Case in point:

"Bomber command lost nearly 50% of their crew during WWII" - "Oh dear that is terrible tragedy - upvotes for you, my friend for pointing out this invaluable fact."

"Lots of German civilians were killed in the floods after the Dambuster raid" - "Meh, who cares? Cost of war. Downvoted. NEXT!"
