General Motors not only did a fine job for the United States during WWII but also for Nazi Germany. General Motors was the largest car manufacturer for Nazi Germany and had other corporate interests especially Opel also involved in war production for the Nazi's. General Motors war production for Nazi Germany was filtered through the many companies it owned in Europe particularly in Norway and Denmark. General Motors received $33 million dollars in reparations for Allied bombing damage over Germany during WWII. Of course the FBI investigated and determined that General Motors activity in Nazi Germany was collusion but of course not traitorous. And let's not pick on General Motors when you have Standard Oil, IBM, Kodak, General Electric, Coca Cola and Chase Bank still the model for laundering money for Mexican cartels, European drug cartels, ISIS and of course Al-Gaeda at it's peak, all who participated in Nazi Germany's military build up and war effort.
