How much did the passage of the Treaty of Versailles affect Hitler’s rise to power/campaign?

Not to forestall further (comprehensive) answers, but there's some discussion of the harshness of the Treaty of Versailles in response to previous questions, including:

/u/DuxBelisarius on Was the Treaty of Versailles really that bad?
/u/kieslowskifan (in excellent detail, discussing hyperinflation etc) on Was the Treaty of Versailles too harsh?

Hope that helps!
