It's simply not possible. EU law has no provisions for kicking a malignant country out. It was simply not foreseen. They can only decide to leave themselves. Which orban will never do because his oligarchs make billions off EU subsidies.
If it were it would have happened already.
EU2: the no-Hungary club
It's not possible with the current rules. Ultimately if every EU country other than Turkey wants them out, what are they going to do?
Order is on the verge of breakdown I wouldn't be surprised if they just lose their voice/get kicked out.
Trump etc are tearing down international order. The ramifications of this will be decades long.
They cannot make them leave the EU, no. But Hungary can be:
- kicked out of the Schengen Treaty
- kicked out of the NATO
- fined under EU breach of contract proceedings
- withheld financial support as long as they do not pay these fines
- forced through customs policy, which is sole EU competence, to stop compensating lost EU support with Chinese money
Honestly, I'd be in full support of some above listed actions if the elections in April show the current will of the Hungarian people misaligned with shared EU values.
