User blog:Atewell/Universal Language?

I have a question maybe you guys can figure it out. A lot of people say the countries communicate using a universal language besides their nation's language, however England always complains about how America uses improper English (at least in the English anime dub and manga). How can he do that if they are not all speaking English and how does that work in the original (Japanese) and other translated versions? (sorry I am bored and that always bugged me lol)
