Although up to now there is no evidence of an order to kill all Jews, but see above and you can see there were orders to exterminate Bolsheviks, Jews, commissars, etc.
I am not so sure about that account of history. Are you saying I can't trust what I've read about what Hitler did?
Yes, and of course the Jews were behind all this.
While it's good to read up on history it can become problematic when it turns into a conspiracy theory such as Jewish people being behind the Holocaust. Many Jewish people perished in concentration camps and people will be hurt and offended if they hear conspiracy theories denying that history. It would be a good idea to visit the Holocaust Museum, in-person or an online virtual tour, to see first hand the evidence of what occurred and learn about the actual events surrounding the Holocaust.
