After 1812 he still believed he could conquer Europe and he even hasn't accepted his defeat. I wouldn't call that the vision of an enlightened ruler.
One can call the campaign of 1813 a necessity for the existence of France -I don't believe that. The results of that campaign were even worse than the ones of 1812, because he lost all his gains in Germany, assembled in all those previous years before 1812.
I would even go further - in 1813 the first seeds of the foundation of the German Empire with the unification under Bismarck were laid, with the subsequent wars between France and Germany as the ultimate result.
Unfortunately I don't have the time actually to study that period more thoroughfully - to much work (2 jobs and a postuniversitary degree to get).
My best wishes for a prosperous 2006.
