Is Stalin the Source of the Modern-Day Concoction Theory?

After the war there were all kinds of reports from all over the world that Hitler had been seen somewhere. The main conspiracy theory alleged that Hitler had escaped in some versions with AFA Brown and his sort of sidekick Martin Borman who died when he'd escaped from the bunker. CIA investigated any reports sent to them but they concluded unambiguously that all these reports were ferny and false now as listeners are probably aware there were quite a few senior Nazis who did actually end up in South America if Hitler had survived how plausible was it that he could have made that kind of escape obviously being a much more well-known figure yeah not really plausible at all.
