After World War II, 50 percent of Americans polled said they didn’t believe Adolf Hitler and Eva Braun had committed suicide in their bunker in 1945, as captured Nazi officials claimed. Instead, they believed the dictator faked his death and escaped, perhaps to Argentina.

This wasn’t a crazy opinion: Joseph Stalin told Allied leaders that Soviet forces never discovered Hitler’s body and that he personally believed the Nazi leader had escaped justice.

At least two German submarines crossed the Atlantic and landed on the coast of Argentina in July 1945. Plus, there were numerous reports of top Nazi officials successfully fleeing to South America, where there was a large German colony.
