In a correspondence in the the 1880s (or possibly 1870s) with German-American political activist Carl Schurz, Schurz warned Bismarck about Germany ever coming into conflict with America, saying an angered/mobilized US would be a mighty enemy and surely ally with France against Germany. Bismarck's comeback was that Britain would surely ally with Germany against any Franco-American combination. Bismarck mentioned it then, and possibly on a couple other occasions.
So the challenge is come up with a scenario any time after 1871 and up through the 1st quarter of the 20th century where a Franco-American coalition fights an Anglo-German coalition.
