He had invaded the following countries before embarking on his programme of genocide:
None of these countries had done anything anti-German or declared war on Germany or anything like that.
Neither, the Holocaust took place under Hitler's administration.
Hitler committed suicide at the last days of the war in europe.
it was an operation by Hitler just before the holocaust took place, look it up
WW2 started before the Holocaust.
Are you implying that the disabled didn't exist before the holocaust?
Neither, the Holocaust took place under Hitler's administration.
He died before it ended.
he just retained the power that he had before the Holocaust.
The Holocaust (and World War 2) ended a few days after Hitler committed suicide on 30 April 1945.
Hitler spent time in Vienna as a painter, and he also was part of the German Army fighting in World War One. That experience helped set him on the path to his role as Germany's leader, and the holocaust.
no it was during and before WW2 when Hitler started gassing Jews
No. He was the COMPLETE cause of the holocaust happening. He spread abusive and vicious propaganda about the Jews throughout all of German territory to get them to turn against all Jews. The Holocaust probably would not have happened without Hitler, but there were many more factors and influences that had to be in place before the Holocaust would happen.
There are people called "Holocaust deniers" but Hitler wasn't one of them, since he killed himself before the horrors of the extermination camps reached the popular consciousness.
560,000 Jews Lived in Germany prior to the Hitler coming to power
Yes the policy was documented by Hitler in "Mein Kampf" before he came to power.
Hitler committed suicide at the last days of the war in europe.
The simple answer is that he didn't. He re-branded an existing political party into the NSDAP. The Holocaust may have started before the order for it to start was given, of course it started because Hitler wanted it to, but that does not mean that he started it.
