The 'OMG Scary Nazis, lets put everything under the control of a single unified state' idea doesn't appear to make any sense.
Surely if you're worried about Nazis taking over, you should be encouraging the existence of small independent nations, so that when they take over in one place, the damage is limited in scope.
Creating a federal European state is like giving the Nazis all the apparatus they need when they become strong enough.
Remember that in real life both Hitler and Mussolini came to power in countries that had been formed some 60 - 70 years ago from unifying smaller states into one.
