By what you've presented Wilders is Yet Another surviving example of the various ethno-nationalisms that were so popular in the Austro-Hungarian Empire around circa 1900 - Zionism being one - and then spread Euro-wise after WW 1: Italian and Spanish Fascism, the NSDAP in Germany and Austria, Oswald Mosley in the UK, Quisling's Nasjonal Samling in Norway, & etc.

There was a Dutch variant as well, tho' damned if I can remember what they called themselves.
