One of the best books on this issue I've read recently was "The Myth of the Eastern Front".
It depicts precisely what you talked about: how the memories of the Eastern Front and Russian participation in WW2 were effectively erased from the public memory in US and Western countries.
Moreover, the authors argue, that the American popular culture to the large extent adopted what was initially the German wartime view on Soviet Union, e.g. Wehrmacht soldiers were flawless knights that used superior tactics and weapons to defend European civilization from Eastern barbarian hordes. Wehrmacht war crimes were politely put under the rug in favor of building the image of anti-Bolshevik fighters.
Americans put Franz Halder, the man who designed plan Barbarossa, in charge of the network of German generals who prepared hundreds and hundreds of materials on Eastern front to consult US military. Many guys like Adolf Heusinger seamlessly moved from Hitler's bunker to the chair of NATO Military Committee. Manstein and Huderian wrote popular memoirs that reinforced German variant of Eastern front history in Western public opinion. Sure, they omit "the bad parts", like their involvement in genocide, and claim that they lost only because they were outnumbered and Hitler gave unprofessional orders.
Surprisingly enough, recently I witness the revival of interest towards Eastern front. Not only the large number of related history books hit the shelves, but many PC games exploited the topic. Maybe I'm wrong, and its my subjective evaluation biased because of my own interest in the subject.
