Having Hungary with its power to veto everything as a member, is probably the biggest mistake ever done by the EU.
The bigger mistake was not ensuring that the standards that must be met to even get into the EU also have to be maintained to keep your rights within. If that were the case Hungary may not have a say anymore and would not get EU money either until they fix that. After all it seems like the only thing or an cares for is his and his accomplices money.
