well its weird to say but honestly it lead to the early victories because of the belief that they were the best plus it lead to a unification of germany.
a counter argument would be that it was the down fall of germany because they became to cocky leading to the war on both fronts which ultimatly defeated them, but honestly it was only hitler that thought he could continue to take russia in winter leading to the down fall.
MY ANSWER
so i would say that the totalotarian state was the cause of early victories not defeat.
