Which is an indication that the whole system is simply too weak. EU was originally founded to make trade easier. Even the temporary removal of borders for EU citizens was only done to fasciliate trade, the free travel amongst EU states was a nice side effect which could also be used to lure the citizens into believing the EU was actually more. The social apsect was originally only a side effect of fasciliatating trade. And now that it starts to show that the different member states have different political agendas, and not everything can be pacified by just making commerce happy, the system starts to crumble. I still remember the biggest fear of EU when brexit came up. That more member states could have a similar idea. That isn't particularily showing strength and confidence.
