With that background in mind, it would make perfect sense if AIM succeeded in creating (or recreating) the Tesseract in CA: TWS.
I don't think that, sixty years later, HYDRA would still care about Nazi racial ideology. Sure, no explicit evidence, but its not like Red Skull overly cared about such, himself.
