The same family that built modern American capitalism also funded the scientific institutions that gave Hitler the intellectual framework for the Holocaust. Then, after the war, they donated the land for the United Nations headquarters and positioned themselves as architects of the postwar world order. This is not a conspiracy theory. It is, in large part, a matter of public record. In this video, we trace the full arc of the Rockefeller family's most hidden chapter — from the Rockefeller Foundation's systematic funding of Nazi eugenics researchers at the Kaiser Wilhelm Institutes, to Standard Oil's corporate "marriage" with I-G Farben that kept Hitler's Luftwaffe fueled even after America entered the war. We examine the Senate investigation that a future US president called treason, the five-thousand-dollar fine that made it all go away, and the Chase Bank branch that stayed open in Nazi-occupied Paris throughout the war. Then we follow the pivot — how the same family that helped arm the Third Reich turned around and bought the land for the United Nations, placed Nelson Rockefeller at the founding conference in San Francisco, and spent the next half-century building the institutions of global governance through the Council on Foreign Relations and the Trilateral Commission. This is a story about what power looks like when it operates through foundations, banks, and international bodies rather than armies. And it raises a question that still matters today — who really built the modern world, and on what foundations?
