> Since it’s known that Nostradamus misspelled Hitler as “Hister”,
Is it known? Because that's a pretty big leap. Hister refers to a river in Germany. In fact in his actual passage it refers to 'Hister' as a place, not a person.
Most are vague enough to be completely useless, I agree, but this is pretty clear. I guess your documentary wanted to have some sensationalist content, a-la 'ancient aliens', but no, it is not 'known' that Nostradamus predicted anything let alone WW2 after misspelling Hitler. In fact he references 'Hister' a few times in his writings, referencing a pretty large river in Germany.
