Germany isn't fully unified because Austria is independent.
Based on your description, I take it you are referring to the German people, not the nation. In which case, yes. Not all German speaking people are unified under one nation. The same could be said for a lot of demographics.
@Haroush, I actually want an independent Austria, if anything I like dividing up countries more than uniting them, simply because they tend to be more peaceful and more efficiently governed. This poll isn't trying to promote an agenda, I just want to see what people think since people often refer to Germany being 'unified' after the Cold war, but the natural questions that arise are: What about Austria? If Bavaria was independent in place of Austria, would we still consider Germany unified?
