And he was also too cowardly to own up to being a Nazi. He believes the Jews started WWI, and he believes the "Stab in the Back" myth. Two firm pillars of Nazi ideology. That, along with the aforementioned cowardice, is three strikes and you're out, Adolf.
To be fair to the OP, someone should have asked him if he would like to annex the Sudatenland to suss his views. Wouldn't that have been a bigger 'give away'?
[Tip of the hat to the MP record with the gameshow asking contestants what they would do if they were Hitler. Contestant #1's response was paraphrased above. I don't recall Contestant #2's response, because the radio was being turned off / smashed (?) by a pepper pot as a segue to another sketch. As she turned it off, she screamed, "Liberal rubbish!". ]
If I was Hitler: I'd have read celeb magazines, watched reality TV and soap operas, worn shellsuits and made prisons comfortable places to stay. Then all those things would be unpopular in the modern world
