With the risk of beeing seen as naive Iīll give my view on this matter.
In my belief Nordicism is about seeing and promoting a common ancestry, history and culture from a slightly different and wider scoop than the national state. Scandinavia and northern Germany has all these parameters, and I canīt see it as nothing but a logical consequence that friendship is sought, especially in times like these.
But as soon as it is done on behalf of the wider European interests, or starts to include non-European interests, itīs out of bounds.
But those are just my personal opinions and they may at times be a little naive.
