I highly doubt that Jewish bankers like the Rothschilds would have anything to do with the NSDAP. Jewish opinion on Germany had already turned in 1933, see the famous 'Judea declares war on Germany' Daily Express front page when Hitler took power in 1933.
Nationalism -in whatever form- and globalism are opposites. So I'm having trouble buying into the premise that National Socialist Germany somehow is a ploy by (among others) Jewish globalism.
Because you're only looking at the small picture. Funny you don't find American banks and industries supporting Hirler odd, only Jews
Should I be surprised that a fiercely nationalist industrialist like Henry Ford was sympathetic to Germany, or many people in the US that came from German countries?
The Rothschilds, who are Jews, are the biggest bankers in the world. Germany during Hitler's years repudiated international banking schemes and revised their monetary systems drastically (think theri MEFO bills to develop industry). Why would American globalist institutions support a nationalist endeavour?
And to circle back, Jewish banking surely didn't do that. A name like Jacob Schiff, one of the biggest bankers on the US East Coast, bankrolled Lenin and Trotzky in Russia. Communism is a globalistic ideology, and globalist institutions (plus the Jewish link between the likes of Schiff and Trotzky, though the Cold War dialectic should make them sworn enemies, but they weren't) supporting them makes a lot more sense than them supporting Germany at the described time.
