@Walter Hinteler,
I've travelled to Germany several times and enjoyed everything I saw. In many ways I found Germans to be very similar to us, with a wry sense of irony and amusing regional rivalries. ( I recall warnings from a Bavarian friend about the supposed poor quality of the food in Berlin.) My wife's grandfather was a Professor at Humboldt University and had a home in Charlottenburg, west of the Brandenburg gate in an area that is now parkland. Five Haeussler sons left in the early 1920s settling in Chile, Mexico and Puerto Rico and starting now large family groups in each. We've visited them all, and found that, even after two generations, they're all remarkably similar.
My impression is that most European nations are suffering from the influx of (so far) hard-to-assimilate immigrants from the Middle East & Africa. Reactions are underway, taking various forms across the Continent. Initial reactions here to the floods of Germans, in the 1850s, and later Irish, Polish, Jewish, & Italian were similar, however in retrospect a few generations later it all looks rather benign. My parents were from Ireland and I grew up in an ethnic stew in Detroit, where the boundaries of each national neighborhood were known and well defined. We all had epithets for the "others". (I was 12 when I discovered the term "dumb Polack" was really two words, and that they had a similar term for the Irish - by then it didn't matter)
I was surprised to see that Angela Merkel ( a former physicist) so assiduously took in the Global Warming frenzy, shutting down a well-functioning nuclear power system that then provided roughly 40% of the country's need, making them dependent on expensive imported fuels. My impression is that Germany needs inexpensive, abundant energy resources to restore it's now fading economic dominance. The initial capital costs for restoring it will be high, but the operating costs are low and it appears to be the only effective long-term solution. We need to do the same , and I believe the new AI revolution, with its enormous power requirements and widespread public appeal , it will happen.
