I personally think that the EU could be remoulded if FN wins in France, AfD in
Germany and Meloni is in power in Italy. Until there is a strong national-socialist / fascist force (which are legitimate political streams) nothing much will happen to the Dutch EU membership. I strongly believe AfD for Germany will accrue even more power than the PVV, and if that happens eyes will be on France. Were the French elections to coincide with a strong inflationary flow and / or recessions who knows what could happen as then there would be a major block in the EU that would be a hardliner against migration.
There are easily exploitable sentiments so this bloc could come up with some kind of "united native Europe" ideology against foreign infiltrators. That everything non-European threatens the ancient and supreme European way of life. Most Europeans are in the end conservative. They don't want to give up their way of life and regional drinks and food is deeply entrenched in many of the European nations that are threatened by green energy policies / global warming by making them too expensive for ordinary people to enjoy. This will be one of the major developments to be exploited by nationalists, as well as inflation which can be casted as capitalism gone too far.
The fact that the Dutch elected the farmers party as #1 in the regional elections rhymes very much with the farmer as the perfect national-socialist, unburdened by cosmopolitics, capital to forego work and foreign influences. The supreme soul of the nation state burns inside him, ready to zealously toil for the benefit of the only nation he deeply knows. Also pay attention to the historically low fertility rates and how this could be used (we must multiply lest we are taken over by muslims).
Trying to take on the EU alone is never going to work, and a Nexit would be disastrous for business. In my opinion, if someone is annoyed by the EU rules, internal gridlock is vastly preferable over a full-exit.
Be careful what you wish for, national-socialism is at heart a deeply anti-capitalist force with as culprits of the propagation of capitalism the UK (which has left the EU and is a bit of an outcast) and the United States.
In my opinion one of the biggest failures of the EU is the inability to have united at least Western-Europeans across the lower-classes. Frankly people were more concerned about helping non-Europeans and now the existence of the bloc is threatened by sentiments against those very same non-Europeans.
