IMHO, the rise of Hitler and the Nazis had more to do with fear of Communism and the Great depression than Versailles.
A great book on that is "The Wages of Destruction" by Adam Tooze.

One little known fact is that much of the reparations Germany was obliged to pay to Britain and France was financed by loans from the U.S. and the U.S. was fairly lenient in refinancing these loans. After Hitler came to power, he in effect reneged on these loans so it is not true that WW1 reparations put an enormous strain on the German economy.
The real question is whether Hitler would have come to power if the Russian Revolution had never happened.
