We all have our own reactions to these things, depending on what we are familiar with. Obviously I knew you were reading German, though the pronunciation (forgive me) didn’t make it easy to follow all of it (sorry…). When you got on to “zwei deutsche Staaten” I assumed this was a text from the Cold War.
As for the clip posted by Nineberry (from a man I greatly admire – Qualtinger, not Nineberry!): this was another moment of Verfremdung, as Brecht used to say, because it’s not Hitler’s accent at all: it’s Viennese (naturally enough, since Qualtinger was born and died in Vienna): he slips in a few things that Hitler used to do, pronunciation-wise, but it doesn’t change the general impression, of someone from Vienna doing a take-off of Hitler. Sounds like an American trying to sound British, and not doing it very well (or an Englishman trying to sound American and not really having a clue how, beyond inserting an R in unexpected places).
Someone who comes astonishingly close to the original, in my opinion, is Bruno Ganz, in Der Untergang.
Makes me wonder why Qualtinger did this. Qualtinger, for those of an English-speaking persuasion, was a theatrical performer of political satire: a “Kabarettist” (which has nothing to do with “cabaret” as the term is used in English: that is called “variété” in German). I saw his “Der Herr Karl” in Vienna (not with Q himself – bit before my time!). What did he think he was doing this time, reciting Mein Kampf in a non-authentic accent, but with a number of well-imitated mannerisms and idiosyncrasies? (If he was doing it for a local audience, the mannerisms and idiosyncrasies would have been quite sufficient.)
For me, it embeds Hitler’s words in normality: here’s someone talking in an accent in which I would expect to hear normal, everyday things: I had a business meeting just the other day with someone from Vienna; and here he is, spouting out this outrageous stuff.
If I see footage of Lenin or Mao, or anyone whose language I don’t understand, I have a reaction that is probably like that of a couple of the posters on this thread: it’s weird, eerie, troubling, demonic, and so on. The lightning conductor, that brings it down to earth and dispels all the diabolical atmosphere that has gathered around it, is when you understand the actual words and realise what a load of banal, stupid rubbish it all is.
