Germans have had the “nationalism” beaten out of them after two world wars, and especially by the global elites from the past 70 years or so.
Why can’t Germans simply love their own country and be proud of her (or his—it is the Fatherland, after all) accomplishments?
Instead, they have to whisper to each other, and yes, the occasional American (me) that they do, just like any other people do. Else they’re called imperialists, HRE evangelists, Teutonic knights or worse—Nazis.
Ditto the Nips.
No, it was not beaten out of them, thanks to the left in the USA who built them back up and facilitated the EU to make them dominant on the continent again. No chance for them to learn anything of what the US Founding Fathers conceived as a free society; the US left is in full agreement with people like Marx and Hegel, sadly.
There are lots of Germans who are as you describe, but it’s the leadership that lies to them and leads them down the wrong paths. Right now, Germany’s media broadcasts the most virulent anti-Trump propaganda, even more so than the US media.
