What about that monument in Coventry to "The Brave Men Of The Luftwaffe"?

I can respond to that.
There is none.
Neither are there any memorials in Germany to the brave men of the USAF or RAF.
There are war memorials to the dead of Germany in Germany however, and similarly in Japan.

Should the victors of that war go back and tear them down?
That would stir up resentment and hatred too.
