With a world that is becoming smaller and smaller (with the help of communications and the internet) we need to find more easy ways to communicate with each other. The world being smaller in this respect is so good for so many reasons, like the issues of countries being humane or not. Instead of shrinking more and more into dialects its better to find a unified tongue. For example, English. However, with there being a few countries as German as their official language, they can only strengthen the language itself and encourage others to learn it by them all keeping it the official language. Otherwise they will be forced even more so to learn English.
