War with Germany would still have happened. The Weimar Republic was imperialistic, with designs of reversing the defeat of World War 1.
The Treaty of Versailles garaunteed that war would eventually have broken out. Germany was not willing to tolerate that treaty.
Also the hatred of the Jews did not come from Hitler. The German people were strongly anti semetic. Germans have ahd a deep hatred of Jews for centuries. The German people deeply supported Hitler and the extermination of the Jews. Read "Hitler's Willing Executioners" to find out more about this.
What are you talking about?
Weimar Republic was NOT imperialistic, where did you read that? That's not true, and more, they couldn't be imperialistic even if they wanted to, they were in the ass. First in 1923 the "hyperinflation" where you could buy one litre milk for millions, that destroyed the middle class in germany, because the money had become worthless. That's also why Hitler in the same year 11 october 1923 tried to get the power through the force ("putch"). But he failed and was in jail for not more than a year.
Then came the world crisis in 1929 and germany was poor again, for a second time in the same republic. So the circumstances were good for Hitler and the NSDAP, because nobody believed in the republic anymore, and poeple got radicalized, but not only to the right (NSDAP) although to the left ("KPD" = Kommunsistische Partei Deutschland) but in the left, they hadn't a leader like Hitler who could talk to the poeple and make them believe he could do it better. I think that no-one voted only because of the anti-semitic ideals he had. And of course nobody knew he would became a dictator, even he in his early speeches like "Reichskanzler" promised, that he would try his best for the next four years, that they should give him a chance, he asked only for four years.
You say that "Germany was not willing to tolerate that treaty."
The people blamed the Weimarer Republic for accept that shitty treaty totally unfair, the only thing that was broken of the treaty was that they didn't pay all the money, because they COULDN'T.
When Hitler had become Reichskanzler, then they started to not obey that shitty treaty.
And maybe if hitler hasnt been there, the communist would have come to power, and i don't know what's worse.
