You know, I had a funny thought the other day. What do you think the world would be like if the US decided to adopt Latin as it's official language instead of English back in the revolutionary days? It was possible, they could have done so to distance themselves from the English, promote a language that all immigrants could use, and be a reference to the Roman republic days.
