In Franco-German rapprochement in the 20s Streseman played a huge role - he was its main propagator on the german side. But even he didnt give up the revision of the Versailles treaty - using force if need be. If even the more moderate germans like him couldnt accept the treaty it shows that this treaties were really unacceptable to Germany and instigate it to go to war again if needed to revise them.
The Versailles Treaty was really bad and Germany was determined to its revision. I see the Great Depression more as a catalyst that strengthened this anti versailles feelings and made them more evident. But sooner or later a conflict was bound to happen because of german revision plans even without the Great Depression.
Stresseman played a major role admittedly. But even after Stresseman died there was still continuing rapprochement, to an arguably greater extent than when he was alive - this was the time when the first stirrings of a custom union and a joint agricultural policy began to emerge for example, as well as even some considerations regarding joint foreign policy positions on the USSR and Turkey. Of course, Stresseman's death did play a role in ultimately scuttling rapprochement, and nor should it be ignored that there would be adjustments ultimately made to Versailles, as they had during the 1920s on reparations. Rapprochement did not after all, end the conflict over equality of armaments vs. French security concerns. But it was not impossible that Versailles would have provided the gateway to a lasting state of affairs, ultimately integrating Germany into the European community. Of course there was resentment against Versailles, and of course it played a role in what happened, but at the same time it was in my opinion not entirely responsible and its implementation did not necessarily mean that a group akin to the Nazis was bound to emerge.
