The US elites and many other foreign elites played a major role in supporting Hitler’s bid for power and continued that support even during the war through various front companies. Mountains of US and European money helped Hitler develop Germany into the formidable opponent that they would become.
Rothschilds, Rockefeller, George H. Walker, Averell Harriman and numerous others all supported the SS. However the people most deeply embedded were the Dulles brothers, which we still have an airport named after and Prescott Bush.
How is it that any major event always has someone from the Bush family tied to it? Not in a “save the day” good way either. From Nazi ties, JFK assassination and business ventures with the BinLaden family, their name is always linked to something nefarious.
