Its important to understand the context. Germany, and Europe in general, is basically like a falling empire. It will be less and less significant and life won't get any better than it is relatively speaking. The same will almost certainly happen with the US, but first goes Europe.

Unfortunately citizens and therefore ruling elites of empires fueled by relatively extremely high standard of living for decades in comparison to the rest of the World always have very hard time swallowing their national pride. They have built very elaborate conceptual framework of linking their nationality to the level of relative success, fueled by politicians who want to make people feel good again about their nationality.

Just look at the news, almost everything directly or indirectly is linked to the concept "nation".

And in almost all cases of empires a natural consequence of their fall is war. So, it is very important to set expectations right.
