You're probably thinking, "Wait a minute. IBM was American! The closest America ever got to the Nazis was when Indiana Jones wore that uniform as a disguise in Raiders of the Lost Ark!"
Actually, prior to the war, American business took what can be generously described as a morally ambivalent stance on the whole Hitler thing. American groups, such as the Rockefeller Foundation and the Carnegie Institute, directly funded Nazi eugenics projects in the early '30s (where the goal was to find ways to breed a master race). Of course, once the war started, most American businesses cut ties with Hitler. IBM, on the other hand, decided to stick around and see where he was going with this whole final solution thing.
