At this point i don't know. Unfortunately a large portion of the population of most EU countries is still deeply entrenched in liberal European chauvinism and EU worship. The liberal delusions are still going strong. It might take a collapse-level crisis to shake them out of it. The problem is that it doesn't take a majority of the population to buy into the EU ideology for Brussels to maintain power. They just need a large enough minority so that they can rig and manipulate elections through media, NGOs, lawfare and EU funds.
