If you're not familiar with the Vatican ratlines, ODESSA, or the Rise of the Fourth Reich then this video will lead you right up to the rabbit hole. Be careful you don't fall in.
If you ARE familiar with the organizations that were formed around helping SS officers and other high Nazi functionaries to escape JUSTICE after the war, then this video will be equally entertaining if you like taking note of omissions and distortions.
The ODESSA (from Organisation der ehemaligen SS-Angehörigen) on Wikipedia - Ratlines were a system of escape routes for Nazis and other fascists fleeing Europe at the end of World War II, more on Wikipedia.
