In a nation state, it’s easier to pull off authoritarian shifts, because citizens will not usually revolt over such things alone. But the EU relies on sustained support and a positive image. There are already at the very least 10s of thousands EU skeptics created from the last wave alone, and probably much much more to come.
Zooming out, I think this is the time when the EU is needed the most, given the geopolitical developments. Both Russia and China are drooling about a scattered Europe consisting of isolated small states. That makes it more infuriating. Someone, ideally the press, needs to dig into the people behind this and expose them.
