What if in 1776, German was chosen as America's official language instead of English?
Would the US still have been on the allied side during WWI and WWII?
To echo the above posters...
Firstly, the United States does not have an official language, although certain states do. English is the de facto tongue, because the vast majority of the country speaks it, but there is no legislation to warrant this place.
Second, despite the urban legend floating around that the US considered adopting German as an official language, it never happened. It is a gross exaggeration of an instance when the House of Representatives declined to translate a law into German.
Thirdly, Even assuming that somebody brings this up at the constitutional convention (the continental congress have more pressing matters to attend to), the idea of it being accepted is ridiculous. Why? Because the thirteen colonies were, with the exception of certain areas (such as the region of Pennsylvania settled by Germans), overwhelmingly anglophone. Why are they going to adopt German, of all things, as the official language, especially when most of them don't understand it?
