Three regions of Denmark preventing it to be a "perfect" nation-state are:
1. Region of Southern Denmark- The border between Denmark and Germany does not fully divide German and Danish nationalities
2. Greenland- It is Danish territory in the Atlantic ocean and it does not have Danish cultural characteristics. The names of the cities are written in a local Inuit language.
3. Faeroe islands- Just like Greenland, they do not share Danish cultural characteristics.
