If you divide Germany, the first natural goal of political leaders of the divided states will be to unite again. You know as well as I do that this will happen sooner or later and the German population would eagerly support the unification, which they believe is one of their crowning historical achievements. That would also destroy German-French relations forever and I won't even mention the fact that Russians would become a bigger threat... Therefore, I think that dividing Germany into several states would be a reckless action which in the end would do us more harm than good.
