I doubt it would compare with Denmark, Danish nationalism is fundamental build in opposition to German identity, Denmark was always a poor rural puritan backwater dominated by the more cultivated German identity (which build it own nationalism in opposition to French), Netherland was different, a rich, diverse, cultivated centre which sucked immigrants from the entire Europe to it.
I did not mean the Dutch or Danish identity. I just meant that the Dutch Rhineland and the Netherlands would be in the same position as the Danish Schleswig-Holstein and Denmark.
