Nazism seemed a subset of a larger plan.The Germans were simply chosen to be the bad guys that time. If the Bank of International Settlements could survive when everything around it was destroyed, maybe the protection of financing indicates a larger deception. The United States (especially the North East) was roughly 50-60% German descent around this time. Creating the environment to wage war on the ethnic origin state is a hard sell requiring very specific levers to enrage the American people.
