Prof Jorjani has plummed aspects of 20th Century history that you never wanted to know about. Ford Motor Co, Rockefeller and Chase Banks, J.P. Morgan, and IBM all had deep ties to the Nazis. So did the British royal fmaily. American and British institutions were responsible for funding Hitler's rise to power, and also for creating safe havens and new identities for thousands of Nazi scientists after the War.
Jordani talks about a "breakaway civilization" that he speculates thrives (literally) underground today, using technology from Nicola Tesla and from Nazis research projects. This is a mind-expanding video, and I don't have the capacity to judge its credibility.
