No not really, I can say from an IE point of view, the reason the border at northern Ireland was such an issue for Brexit was because the good Friday agreement was because this was done outside of the EU. If the EU had the same authority as the Federal in the US as an example, there would be a hard border. General framework yes, for regulations, but how you run your government, absolutely is up to you. Just look to Ordaban in Hungary. Not exactly playing well with the EU, doesn't mean the EU can force him to do something. Edit : Again there are nuances with the EU. And there are issues, but overall it works really well. - Was going to correct Orban's name but he's worth less the effort than typing this.
