In 1870, Germany was widely considered inferior to France, hence why the international community was so amazed when the French lost the war. International historians today blame the French aristocracy's incompetence for losing that war btw, and not any specific German competence.
In 1914, Germany lost another war and was humiliated internationally. 1914-1870 is 44. Wow, what a long era of international dominance for Germany! From then on the USA was on the rise (and British Empire was still the world's main power), and English became more and more important as the world's dominant language, easily crushing German and French :'(
And are you somehow trying to take credit for America literally pillaging your universities and looting the burned husks of your research centers? From that point on the achievements of America must be recognized as American. And indeed, the few German scientists who did do great things flourished only when in America's own research environment! Going to the moon is far better than shooting a few rockets across the Channel!
And for more proof of French's historical dominance, look at the invention of German social sciences! Weber, Tönnies, and people like Norbert Elias? All these people who started the big German intellectual movements focused around culture, "what makes a German","what is German culture"? Sure they did great things and these German intellectual movements have produced interesting content, but you have to remember that they started because they felt inferior! The building block of German national identity and German social sciences was "why can't we be like the French? Should we even try to copy them mindlessly like our elites are doing? Why do they have all this great literature being written, innovative art, and soft power so great that royalty from Spain to Russia speak French at court?"
This feeling of inferiority didn't come from the long series of crushing defeats taken by Germany against France until it managed to unify properly into a country vastly more populated than France that would field bigger armies and had more industrial capacity. It came from the cultural, scientific and even political dominance of the French language and culture.
And to argue the beauty of the French language, all I'll say is the fact that "That feeling you can only say in French" became such an accepted sentence in English (the other dominant language) that
people started writing stories based on it. And of course, the phrase "lingua franca".
In a proper world the French would be proud of having kicked off such excellent intellectual developments in Germany. Except that once the Germans got a good thing going they used it to unite into a single nation where the military held ridiculous influence and respect, and then used that military a little too much for their kind neighbors to accept.
