Can you share some of these degenerate cases?
Ah, no who am I kidding. These usually worry about the opposite. What if EU manages to resist to those projects and remains liberal democracies?
But I don't think you can just elect Hitler in every nation and then get them to cooperate. They will inevitably want more and when they do they become aggressive. At which point I guess people will reconsider.
Smells like a long-term attempt to break the EU from within TBH.
