Seriously I don’t know why Hungary hasn’t been booted yet. Corruption is rife, culturally different and Putin-hugging. Well perhaps only good things to come out are paprika and salami
It is almost impossible to boot someone out of the EU - there is no protocol, nothing in the contracts. The EU as a construct is pretty much child of 90s - end of history and such nonsense. There are no safeguards and it is not reformable, since a lot of small countries who have veto rights would all have to give it up.
