Hitler was a psychopath, he lost the war by taking on the red army to the east and us and America to the west
But there is little doubt he died in the bunker
As for many other Nazis they did indeed flee to Argentina etc , particularly mengele , the angel of death
Infamous.......butcher .......angel of death !!.......martyr to the kingdom of the dead .....angel of death........flying free !!
As the mighty SLAYER so eloquently put it
