Truth be told, Germany needs to again think of itself not as “just a member” of the EU, of NATO, of whatever, but as a unique nation.
After the Napoleonic wars, France also renounced its history and officially despised Napoleon Bonaparte in the nastiest of terms. So much so that there are entire libraries devoted to just him and his reign. Technically, he is the second most written about individual after Jesus.
It took almost 150 years (1815-1965) for the French to finally get around to thinking of Napoleon Bonaparte as a great French leader, even if he eventually lost and was deposed.
And eventually, the Germans will do the same with Hitler. It is almost an inevitability, once he and Nazism and the evil that they wrought, and their victims, are no longer in living memory. It has been 68 years, so it will not be long now where the process will *begin* to see history more objectively. Though generally speaking it is more likely that a 100 must pass before not just the victims, but their children, are mostly gone. This would be the year 2045.
But, in the meantime, Germans have to recognize that they are German, and that this has a cultural and historical significance as a people, completely apart from membership in any organization. A people with a benign purpose.
