Pretty sure it took two tries also
The idea that Germany was in any way the single country responsible for WWI is absolutely ridiculous.
The revolution in Bavaria would still happened. And still irk right wing. The democracy would still be rejected and Weimar Republic would still be one massive mess.
Hitler did not gained power just because of social issues.
(And also, less importantly, had Germany won the WWI, they had plans to ask other countries for large reparations. It is not like those were something unheard of at that time.)
