The Nazi ruling class were capitalist and anticommunist, the Soviet ruling class were communist and anti-capitalist. The "Western" ruling class is capitalist and anticommunist and sympathized much more with the Nazis than the Soviets, it even rescued and employed the Nazis after the war to help fight Communism. The west had a need to portray the nazis as stronger and superior but doing a naughty by invading Western Europe and all the heinous genocide and torture and shit that went public. This needed to portray the Soviet Union as having a twisted pipe dream that sounds seductive and maybe even some of you guys think what they're saying doesn't sound that bad but look what happened to the people when they trusted those commies, they had no weapons or technology or strategy, they just had to throw bodies at the naughty nazi ubermensch to defeat them because communists just treat their citizens like flesh sacks.
The western capitalists liked the nazis and fascists, they appreciated their work in putting down communists and worker's movements all across Europe. The people hated them because of how much pain and misery and death they caused, an entire generation of men or more wiped out in many countries. If the western people knew it was the Soviets that defeated the nazis almost single handedly that would cast communism in a much different light. Nor could the Western capitalists fawn over the nazis, for obvious reasons. So what ended up happening was that the achievements of the Soviet's was understated, their war effort twisted to make them look like savage barbarians and the nazis were cast as the sophisticated and powerful elite force of evil that was bad but also really strong and cool. The western capitalists used the actual barbarity of the nazis when it suited them and overshadowed it with shit like wehraboo fetishism in the media at other times. They also secretly supported and bankrolled underground neonazis and quietly installed the old nazis back into governments in West Germany, the EU, NATO, and several American Domestic agencies, even the intelligence agencies of Israel after the war, and this process applied to fascists all over Europe and Asia. Capital wants you to admire the Nazis and hate the Soviets but not know just how cozy they were.
