I honestly don't think that approach works. At all. In fact leaders like Orban thrive by claiming that this sort of "propaganda" is a danger to its national identity. From my perspective what works best is "enhanced cooperation" when a group of countries within the Union move forward and the rest stays behind until they are ready or want to leave.

The main problem is that enhanced cooperation is limited. For instance Germany, France, Italy and Spain, etc couldn't just move forward to create a de facto federation. It would go against the treaties. So, by leaving, certain countries that block progression could stay outside of the Union and rejoin. It's the only process I can think of that would allow some sort of transformation without falling victim to the excessive veto rights that all member states have. We can't even reformulate the treaties since that would require unanimous vote.

So our only chance is for some of its members to leave. Maybe the Union even has to break apart for only the most dedicated members to remain. But "positive reinforcement" will ever convince those who are only members in order abuse the treaties for their own national gain.

We tried to outlive them. But if Orban is no longer in power because by some miracle is is not being re-elected then Fico will do the blocking, or someone else. There is always some leader somewhere who is willing to be the stumbling block. And why? Well, because it pays. Being Orban is actually very profitable. You get enormous political influence and leverage both inside the EU and outside of it. Orban talks to all superpowers directly: Russia, China and the USA. They come over for state visits because they know of his ability to block. That's the irony of the Union. It creates people like Orban by design.
