I have always found the conventional historiography of the Second World War a lot similar to Hollywood plots: absolute good versus evil, heroes against villans. The good guys have no faults, the bad guys have nothing but faults.
It's winners who write history. Maybe in this case they got the help of movie screenwriters, with their storytelling abilities and imagination. And it's a bonus that Hollywood studios are largely, as nobody disputes, owned and managed by members of the Jewish communitity.
The introduction to the above video on YouTube says:
More people died in the fire bombing of Dresden on February 13th to 14th, 1945 than in the nuclear bombings of Hiroshima and Nagasaki combined. Holocaust (noun) - "Great destruction resulting in the extensive loss of life, especially by fire."
