The actual myth is that the West is/was systematically engaged on the good side in good vs evil conflicts, when in reality WWII was more of an exception in that regard.
The holocaust, which is undeniably evil, is used to to hide all the other evils that lead up to WWII or were committed during it. This capped by the completely unnecessary nuclear bombing of Nagasaki by the US. WWII was not actually an exception, we just pretend it was.
Also, the systematic destruction of civilian targets by allied bombing campaigns: https://en.m.wikipedia.org/wiki/Area_bombing_directive
Another example is the systematic starvation of German populace in the post-war years, due to the allord policy of deindustrialization. The average daily food intake was estimated at 1000kcal! And it was not a matter of food scarcity - it was a deliberate allied policy:
>Germany received many offers from Western European nations to trade food for desperately needed coal and steel. Neither the Italians nor the Dutch could sell the vegetables that they had previously sold in Germany, with the consequence that the Dutch had to destroy considerable proportions of their crop. Denmark offered 150 tons of lard a month; Turkey offered hazelnuts; Norway offered fish and fish oil; Sweden offered considerable amounts of fats. However, the Allies disallowed the Germans to trade.

WWII being the fight of good versus evil is the foundation myth of post-1945 western civilization. It is the central dogma of the western pseudo-religion, which prevents meaningful discussion of these matters.
