Moreover, American assistance to Nazi war efforts extended into other areas. The two largest tank producers in Hitler's Germany were Opel, a wholly owned subsidiary of General Motors (controlled by the J.P. Morgan firm), and the Ford A. G. subsidiary of the Ford Motor Company of Detroit. The Nazis granted tax−exempt status to Opel in 1936, to enable General Motors to expand its production facilities. General Motors obligingly reinvested the resulting profits into German industry. Henry Ford was decorated by the Nazis for his services to Nazism. Alcoa and Dow Chemical worked closely with Nazi industry with numerous transfers of their domestic U.S. technology. Bendix Aviation, in which the J.P. Morgan−controlled General Motors firm had a major stock interest, supplied Siemens & Halske A. G. in Germany with data on automatic pilots and aircraft instruments. As late as 1940, in the "unofficial war," Bendix Aviation supplied complete technical data to Robert Bosch for aircraft and diesel engine starters and received royalty payments in return.
In brief, American companies associated with the Morgan−Rockefeller international investment bankers – not, it should be noted, the vast bulk of independent American industrialists – were intimately related to the growth of Nazi industry. It is important to note … that General Motors, Ford, General Electric, DuPont and the handful of U.S. companies intimately involved with the development of Nazi Germany were – except for the Ford Motor Company – controlled by the Wall Street elite – the J.P. Morgan firm, the Rockefeller Chase Bank and to a lesser extent the Warburg Manhattan bank. This … is not an indictment of all American industry and finance. It is an indictment of the "apex" – those firms controlled through the handful of financial houses, the Federal Reserve Bank system, the Bank for International Settlements, and their continuing international cooperative arrangements and cartels which attempt to control the course of world politics and economics.”
