The problem is the nature of the EU. A significant number of activities involve UNANIMITY of all their nations or at least nobody actually voting in opposition, sort of like NATO needing unanimity of approval for new members. It gives these relatively little and inconsequential countries a veto over many things requiring the rest of the EU to somehow buy them off with concessions in other areas or just not be able to act. Hungary has been working this scam for some time now. Czechia and Slovakia are now getting into the act as well apparently.
