In the short term, this will likely be a good thing as well, because it stands in opposition to the hegemony of the EU, *and* to Germany endlessly bailing out the failing socialist EU nations.
And even if Germany again becomes a nation equipped with a military, hopefully they can pick up some of the slack the US has when there is a worthless Democrat POTUS.
Germanys recent wave of partiotism was not agressive in difference to the past. I am living here and I can not imagine that nazism ever could rise anymore. Nazism itself is a crackbrained concept and this is something that is well understood on our side of the Atlantic. Nevertheless Germany will define itself more self confident in the future. Such could mean that it will kick out US-spies and it will react on unfriendly actions also quite unfriendly. Not a occupied area anymore. Furthermore among the German public it is understood that Germany is economically the most powerful nation in Europe and that means a great responsibility. Together with the rest of the continental European Union Germany remains a key partner of the Brits (who never belongend to Europe) and the Americans that now has much more possiblities than in the past. The spying made Germans more flexible since that makes them free of old psychological obligations. Nothing will happen very fast but it could be quite sustained.
We will see what will happen after Putin and Merkel.
