What if France won the Franco-Prussian War? Good question.

Now first, the desirable POD is this: Austria, wanting revenge from their defeat in the Austro-Prussian War, decides to join France in the conflict. Overwhelmed, Prussia is forced to surrender.

With hopes a united Germany gone, France remains a major power in Europe.

Any effects?
